Friendly reminder to get a UPS.
I just lost an entire day's work because I'm a stupid idiot.

>>106129491 (OP)
Did you kick the cable?

I tried to run without UPS for like a week, had my computer shut down from brownout. Never making that mistake again.

>>106129491 (OP)

I have a whole house UPS and solar panels. Sucks to suck yuropoors!

I've had multiple for years. My big one I got for free since the person who bought it originally didn't realize you can just change the battery and was throwing it out.

sorry third worlder, I will NOT buy a shit house fire generator from Xi's china shit shop

>>106129501
I unplugged the wrong power cable while running maintenance. I've been using a 4-in-1 USB charger for my mobile devices but it was defective. Every time I plugged my phone in to recharge, the other three would disconnect from the power spike. I bought four separate chargers so this wouldn't happen and thought it would be a good idea to power off the entire power strip before getting to work. It was entirely my fault.

>>106129539
Buy an american made one then.

A customer ours tried to hot swap the hotswapable batteries of his UPS and shut down the whole system destroying their SQL Database.

>>106129809
I did, he said he didn't care and didn't want it. It's ran for about 15 years now just fine. Swapped the batteries two or three times now. It takes two large 12V, 18Ah SLAs.

>>106129836
should have plugged the ups into another ups

>>106129836
lolwut
can't it run on AC while he's hot swapping?

>>106129717

Once the battery dies

>>106129936
I tried this once with a cheap scrap UPS and nothing happened
Then I tried the same after making a cable with reversed live and neutral and it blew up

Last week I accidentally git checkout . in the main project folder instead of the sub folder that needed reverting.
Lost half a day's work how would a UPS save me?

>>106129671
Been thinking of getting one of these for a while. How safe are they? They're so fucking expensive now.

>Working on a thinkpad connected to a monitor and mechanical keyboard

>Then I tried the same after making a cable with reversed live and neutral
I wonder what this does electronically. At first I thought you were shorting the backup circuit. But maybe something else happens?

>>106130017
they make crystals anon dont do it america is not ready for power strips because of the jews

>>106130026
electrons go wrong way

>>106130063
Electrons flow very slowly, what actually moves is the field.

Let's think about this.

If you reverse the phase of your wall plug, the ups will still work. the basic schematic is it's a power supply (ac to dc) and then a charge circuit that switches out seamlessly (how it does it seamlessly I don't know).

The output side is dc to ac from the batteries to your devices.

Why would combining these be a problem, in terms of the circuit you are forming?

>>106130063
no I have it lmao

ok so you have a ground.

The ground and the "positive" are electrically the exact same, or they're supposed to be.

You probably didn't swap the ground.

I want to plug my €20 Amazon Basica kettle into a bunch of American plug sockets just to blow their breakers.
Just for a laugh.

>>106130026
It connects live to neutral so that's a short.

>>106130200
Would that even cause any issues?

American circuits are lower voltage but can handle almost the same current (15A in America vs 16A in Europe)
I think the water will just heat up slower due to the lower voltage and that's it or am I missing something?

>>106130200
I have a kettle like this and I noticed the power cable gets REALLY fucking hot. I know it's drawing a fuckton of power but I worry one day it'll actually melt

>>106130219
"neutral" and ground are supposed to be the same.

>>106129491 (OP)
my laptop does not have this problem

>>106130269
>but can handle almost the same current
as per the spec yeah, but consider who is building american homes. hint: it's americans

>>106130269
That kettle will attempt to draw 230V 3000W and it will blow the breaker.
An American socket is only good for 1850W unless it is one of the HV ones they use for appliances like electric ovens. That is normally not a socket anyway, but hardwired in.

>>106130269
Since these things use just a simple resistive heater they will only draw half the current because of the lower voltage.
So yes nothing will happen.

>>106130200
>>106130269
BTW: Americans can get 220V by connecting two 110V live wires together that are opposite phases.

So if I were forced to live in America I would get two US plugs and a European socket then wire the live from one US plug to the live of the European socket and the other US plug to the neutral of the European socket.
Then find two sockets with opposite phase and boil my water at full speed (and faster than an American microwave can) - Problem?

>>106130289
>just buy a spec home
>your spec home

>>106130285
He said he swapped live and neutral, not neutral and ground.

>>106130334
I know we think of "ground", but that's literally just a bonus neutral.

>>106130325
completely false
it wants 3000W, so it will attempt to draw that on 110V.
The kettle is now drawing 27A
what do you think will happen?

>>106130315
>That kettle will attempt to draw 230V 3000W and it will blow the breaker.
Nope.
You have the constant resistance of the heating element, so you get something like
R = 220V/16A = 13.75 Ohm, P = 220V*16A = 3520W
Plug it into an American socket you get
I = 110V/13.75 Ohm = 8A, P = 110V*8A = 880W

Fucking nothing

>>106130377
>it wants 3000W, so it will attempt to draw that on 110V.
lol no
that's not how a kettle works

>>106130366
>yeah that third prong doesnt go anywhere really, it's wired to "neutral", it's just +120 and 0 v :^)

DO AMERICANS REALLY

>>106130326
Some redditor did this, got a 240V 20A dedicated socket installed in his kitchen just so he could plug a UK kettle in and boil water in 30 seconds:

>>106130395
You don't understand the problem.

That's fine. You'll really enjoy a Mac computer.

>>106130397
That's just an official socket I think many Americans have to power electric ovens and such.

I was thinking a portable device with two wires plugged into two existing sockets.
Saw Electroboom do this once to power a hair dryer.
It would not just be to get extra power but also to trigger Americans who have been missing out for their entire life when the simple solution was just under their noses.

>>106130438
>I was thinking a portable device with two wires plugged into two existing sockets.
It would need a long enough wire to reach into another room otherwise you're just using the same circuit and will be limited by the same current.

hotswap means you can replace the battery while the device is on AC
if you take out the battery and the power goes down it means the device doesn't support hotswap
maybe not for a gaming pc, but definitely mandatory for a server rack

tits to get your attention

>>106129871
maybe it was an older one where you have a switch you have to actually hit before it switches power over to wall AC directly instead of being on battery/conditioning

>>106130471
Depends if the sockets in the room are all on the same circuit or on two circuits to distribute the load like they are in Electroboom's kitchen.
https://youtu.be/OiwWaIvIeao?t=491

But even if I'd have to plug into a different room that's what extension cables are for.

>>106130491
I mean ok bro, but last i checked America was like 40% white once you remove so called “white hispanics”, and when you take into account the caveat that in America, race is a self-declarative thing like your gender, as opposed to something assigned at birth.

>>106130514
I'm guessing the really professional stuff has redundant batteries so even if the AC goes out while swapping a battery (or more likely between the time a battery has died and someone could get there to replace it) it would still have plenty of power?

I do have to question systems that can't handle a few minutes of downtime though.
Unless it's for an air traffic controller or something it's probably better to have a system that you power down somewhat regularly and know will come back up with everything working again and no data loss.

>>106130514
Booba

>>106130701
If AC goes out while swapping batteries you're fucked. That's infrastructure-tier critical, hospital or some shit. Do such high level contractors even really browse /g/ or am I getting trolled?

Who the fuck in this thread needs hotswappable UPS? What kind of shit are you running?

I have one, saved me PC when my buildings neutral wire failed and burned all my shit. The other day it didn't trigger when I accidentally the cable. Thanks for reminding me to send it to check soon.

>>106130825
i think you're larping because actual mission critical shit has generators and the battery backup is just there to either give time for the genny to kick in or for the server to gracefully shut down.

being able to hot swap batteries is more of a convenience thing, so you dont have to switch over to some other power (or god forbid have the server be down for a whole five minutes!!) source before doing that kind of regular maintenance

and yes /g/ is mostly larpers who buy this stuff (assuming they aren't poorfags) more or less to make themselves feel better and/or flex on reddit. for the most part, a home desktop computer's PSU is entirely sufficient for power conditioning and if you have such regular brown/blackouts that you need a battery backup you should either move out of hooverville or get a different hobby.

>>106130026
>I wonder what this does electronically. At first I thought you were shorting the backup circuit. But maybe something else happens?
I think it probably had a shared pole and all the relays and current sensing only manages the other pole, as soon as i turned it on and the relays clicked it went bang and blew mosfets and battery fuses

But I'm in the reddest of red states. One of the redder counties too.

>>106130825
>If AC goes out while swapping batteries you're fucked.
That seems odd to me.
Go through all that trouble and still have a single point of failure even if it's just for a few seconds.
Assuming you need quite a large battery pack I see no reason not to split the pack into two or three modules so replacing each module one by one leaves a working battery at all times just with lower capacity. - also in case one module fails.

Shit sucks but equity is equity assuming you own the land your putting it on.

Every month paying the landjew is money permanently lost.

How are people losing data with power outages? I don't want to jinx it but I've had power outages before and even pressed the Reset button on my PC case many times and I've never lost anything because I use an SSD and Linux with fsck. Is there no fsck on Windows? Do you guys not have earth wiring? No RCCB breakers? What's the deal here? Am I lucky or are you guys unlucky?

I still make backups, just curious.

I am planning on getting a UPS but not for power loss just for clean pure sine wave power.

depends. if you have a very cheap SSD, it will be DRAM-less, so there is nothing to worry about. if have buy a mid-range SSD, it will have DRAM but not enough capacitors to write the data to the flash memory in case of a outrage. if you buy a high-end SSD, it will have DRAM and enough capacitors.

An ATS, automatic transfer switch, usually they're used to switch between grid and a backup generator, but you could also put 2 UPS

>>106142289
>if you buy a high-end SSD, it will have DRAM and enough capacitors.
No consumer SSD has actual power loss protection.
Also DRAM-less SSDs that use HMB aren't really protected anymore. Anything in host RAM but not on the SSD gets nuked anyway.
The only consumer SSD that you can say is protected against power loss is DRAMless SATA or Optane.

Actual power loss protection requires a significant amount of energy, bear witness to the amount of tantalum capacitors on the end of the PCB on a more enterprise class SSD

>>106129671
100% placebo

>>106136097
If your SSD corrupts itself during a power outage it has a faulty controller. Full stop. You may lose data which was in transit, but it should always be in a consistent state.

Probably unless it has a 200W GPU you're not mentioning.

i always understood it as V*A is the power it draws at the wall socket, whereas the watts is what it can output to your plugged in devices after the efficiency losses etc

>>106144815
A lot of businesses will just offload them the day the warranty on the unit expires because they don't want to deal with potential problems or risk it coming up in a lawsuit that the reason x failed was because of a faulty backup battery
you can get the units dirt cheap and just swap the batteries which are cheap and ubiquitous. its literally opening a latch on the underside and takes 3 minutes

>>106144815
Not really but often normies will get rid of cars before literally any major work is needed.
Most cars are only good for 100K for general maintenance, afterwards it's major maintenance like spark plugs, timing belt, trans filter, etc
That's about the time when certain parts also fail and need replacement, like water pumps, alternators, CVs, wheel bearings etc.

It's not guaranteed things will fail but anything over that 100k mark is unironically considered to be high milage and thus more prone to need repairing. Some people don't want to bother.

>>106144848
It's for stupidity purposes.
There is nothing wrong with it, but normies are stupid.

Not all surge protectors are rated for the same amperage as the wall outlet and not all surge protectors have working breakers. Too much draw can melt or start a fire in the weak link. It's easier just to say don't daisy chain to reduce that chance of being overloaded than it is to teach normies basic math.

>>106129491 (OP)
My computer has a built-in battery.

>>106144786
3-5 years. The big ones, 1000VA or larger, take 2 batteries in series and run at 24V. The smaller ones take 1 battery. Batteries are usually a standard sealed lead acid variety and cost about $20 each.

>UPS
If your whole house doesn't have battery backup you suck LMAO

>>106144897
Well you understood wrong and you can read the power factor article on Wikipedia if you want a formal explanation.

Efficiency is already included in the wattage figure. Watts is how much the battery and output transistors can source, DC. VA is how much the transformer and cabling can handle, AC, with power factor from strongly inductive or capacitative load applied.

>>106144925
>It's easier just to say don't daisy chain to reduce that chance of being overloaded than it is to teach normies basic math.
so if i calculate the draw of all my devices and it falls under the rating (so for instance the surge protector is rated at 2400 joules and the total watts and amps add up to less than that), then i should be good right? this shit is so confusing.

You can daisy chain as many power strips as you want. The danger comes with too much load being pulled from a single plug. I have several power strips plugged into my large APC and it doesn't give a shit. That said I try to make sure each strip is pulling less than 500W at full usage.

>>106145027
Whole house backups never switch over within ATX spec limits. Always stack UPS on site battery on generator.

Skill issue. Have you tried saving more than once a day?

>>106145076
I only buy the larger APC units. It costs way more but it's worht it to not have to replace my entire network of hardware due to a power chimpout.

>>106145070
They're all lowest bidder chinkshit. The only difference is some pay for bigger heatsinks or fancier inverter.

>>106145060
okay i think i understand. so if my ups is rated for 900w 15a, i can plug a surge protector into it so long as all of the devices connected to that don't draw more than 900w 15a total? what about the protector itself? will a 4,000 or 5,000 joule protector overload the ups on its own?

>>106145120
The joule rating is how decent a job the strip does at dissipating a surge. The UPS has a better surge protector built in so the strip it doesn't really matter the joule rating.
I would make sure you don't pull all 900W from one plug. Balance it as much as you can. For example, all your monitors could be plugged into a strip that is then plugged into the UPS, while your PC should be plugged in directly. This about how much power each device draws, the more hunger the device, the more you should try to give it its own plug. If you can't, then put it on a strip with other devices that have very little draw.
Also if you can, run as much stuff on the not battery backup ports as you can. They still offer surge protection but no battery backup. Lights, fans, and other shit that don't need backup can be plugged in to those ports.

>>106145120
>will a 4,000 or 5,000 joule protector overload the ups on its own?
No because the amount of current a surge protector can pass is limited by the hookup cables. They're all equally ineffectual.

>>106134394
>LiFePo4
what's a good brand for these? are they as cheap as the lead ones?

>>106145341
actually... I just watched some video and realized that, maybe, the battery might not be dead. should I check the fuses or something?
also, can I put a bigger battery in these units?

>>106145017
bruh that's a counterfeit battery

>>106145028
>Watts is how much the battery and output transistors can source, DC
ya, from the battery to your shit
>VA is how much the transformer and cabling can handle, AC
ya, from your wall to the ups. that's literally the same fucking thing i said

>>106145481
That's just a standard type of battery made by some other company. It's like calling a AA "counterfeit" because you never heard of whatever brand made it.

>>106140727
What's the TDP of your setup, including monitors and speakers? That's kind of important.

>>106145486
>from your wall to the ups
No, from the transformer in the UPS to your load.

>>106129491 (OP)
that's why my only computer is a laptop

>>106145481
Usually you just have to peel back the sticker on those to see the real OEM's sticker underneath. UPS niggers won't even pay an off-brand run before marking it up 120%

>>106145481
That's a standard battery form factor.

>>106130438
I did that for over a year charging my car. I built this combiner which is basically two relays, each relay is powered by the opposite input to connect it to the output so that if someone unplugs one end, it immediately shuts down the power from the other end.

>>106146094
yes its a standard form factor, but that one has different terminals
dont cheap out too much on noname garbage though
typically a same oem battery will be like half the cost of a APC branded one

>>106146119
not OP so I have no idea which of the two terminal sizes it uses but it's probably these guys?

Nah that's a NEMA 6-20 240V plug for small appliances. It turns out the only reason Americans don't run 240V everything is they don't give a shit.

>>106146298
Actually, the real reason 240v isn't widely used in USA is because they didn't give a shit about making a 15-20 amp range 240v plug that is backwards compatible with 120v equipment and maintains the overall size and duplex receptical abilities.
It's basically impossible.
One option you could do at home is run 4 wire to every outlet and wire the top and bottom outlets to opposite sides of the split phase so each outlet has 240v potential between top and bottom plug.
There are no official dual end plugs but I'm sure you can build one plug which inserts into both outlets for 240

>>106129521
What's the difference between a brownout and a blackout? Or is it like a regional thing.

I'm perpetually salty that UPSes are all bullshit SLA batteries with horrible endurance and shit lifespan, and that LiFePo4 power stations, if they even have a UPS mode, all have a switch over time that's too long for electronics.
Why does nobody fucking make a UPS with LFP batteries? This is some kind of fucking racket, market collusion, there's fuckery afoot that's preventing this from happening. Why can't I just have a nice thing that doesn't need replacement batteries every 3 years?

>>106146539
brownout is a voltage drop
blackout is total power loss

>>106146539
brownouts lead to undefined behavior

>>106145076
You're not supposed to plug / unplug during operation. That's entirely the guy's fault.

>>106146900
Whatever happened in there sounds entirely preventable though.

Are these units SUPPOSED to make a racket after a while? I read that its supposed to be the current regulator but fresh out of the box the two units I have never made a peep but after some months they're audibly buzzing. Well less buzzing and more of a vibration sound, like something inside the unit is hitting the walls and making noise. Gently whacking the thing on a certain side or rotating them sometimes stops or reduces it, so it seems like that component in particular is getting loose and it can be shaken back into place.

If it helps, I put some junk heatsinks on top of them. Are they supposed to get hot so that their bodies expand and don't cause this?

>>106146886
lol

>>106145076
lol

>>106141253
So, what's the point of paying taxes again?

>>106146910
Yeah, by not using the device without a grid connection, like the manual says. You NEVER test UPS by unplugging. The software has a batter test and if you need hardware get pic related. It's not a mobile battery bank.

>>106146900
The reason you're not supposed to do that is that you remove the safety ground connection and you leave the devices connected to the UPS powered up (from the battery) but unearthed, which may be a shock hazard. It's not supposed to be actually dangerous for the equipment, it's safety advice to prevent electric shocks, the UPS isn't supposed to fucking catch on fire if you plug it in while it's running on battery.

I have weather resistant 15 amp industrial grade tamper resistant outlets in my entire house. Is that enough?

>>106149023
why only 15A?

>>106129521
>house air conditioning kicks in
>the sudden power draw dims the lights for a second and kills the computer

>>106149031
Romex is only rated for it. I would go all 20 amp but that requires a total rewire and new circuit breakers.

>>106145064
nta but switch over? Kek that's for poor people. Whole house double conversion

>>106149986
>not running off grid diesel
get a load of klaus schwab over here

I have 3 UPS units.

Two of them are quite good
APC SUA1500I. Purchased this one retail with 2009 GFC stimulus cash. This keeps the internet connection and WFH desk alive.
APC SUA1500RMI2U. Purchased for $25 secondhand. This keeps everything in the rack going.

The other is an almost no-name UPSONIC. Acquired for free when it was marked "defective" at work. They didn't know that the batteries could be replaced. They threw it away, I got it from inside the dumpster. Everything on the secondary office desk is protected by this one.

All are from the mid-late 2000s. Batteries in each unit last between 3-8 years.

Still are all serving me very well!

>>106130332
You can heat/cool that foam house with the power from a single low power American socket, it's going to be Passivhaus level insulated. The fiber reinforced shotcrete is strong too.

My only problem with it is that it's build on slab, but that's true for most American homes.

Anyone have experience with this one? CyberPower CP1500AVRLCD3 Intelligent-System Outlets: https://www.cyberpowersystems.com/product/ups/intelligent-lcd/cp1500avrlcd3/

>>106147964
There isn't one. There never was.

Give me one reason why I should get this instead of doing monthly backups to my hard drives? I've never had any issue after like a decade of doing this and I've got a few 22TB hard drives full of documents, music, movies, shows, pictures, webms etc. All I do is make sure I have a couple backups of the same data in case one drive corrupts.

Consider saving more often.

>>106154234
You should do both unless you're straight packrat computing and have spares for literally every part.

You've got to be a special kind of retard to think saving or backups prevent power loss. The point is to protect your hardware, not your data.

>>106154234
Do both, faget.

>>106129491 (OP)
Learn to save your work dumbass. What could you have possibly lost that couldn't have been saved in 5-10 seconds?

Imagine living in a country that still has power outages. I haven't had one in probably 15 years. A UPS is probably more likely to malfunction and cause my computer to lose power than the grid going down.

europoors always want to take credit for the weather
says a lot about their recent accomplishments

>>106144878
during normal operation (no power surge)
is it loud? any coil whine? does it produce heat?

>>106130200
retard

>>106130326
>Americans can get 220V by connecting two 110V live wires together that are opposite phases
No, it's 240V single phase with 120V center tap. They're shifted 90 degrees not 180. Hence the term 'split phase'. Only very large houses see both 120V taps. True dual phase power only exists for ancient industrial deployments in Boston afaik.

>>106129534
Give it back Jamal

>>106158049
mine produces a coil whine when the screen is on. no heat. no noise.

>>106158208
Black people don't use UPS's, they just run an extension cord from their neighbors house because muh re-puh-ra-shuns 'n sheet.

>>106158049
The fans spin up when it's in battery mode. No power surge mode means completely silent.

>>106158286
>coil whine

Mine doesn't have coil whine but I believe it.

>>106129491 (OP)
I lost an entire day's work because I sat around doing nothing.

>>106158286
>>106159642
thanks.
i'll get the one from costco since its my first ups.
its been kinda annoying having to turn off my nas when it gets windy.

>get a cyberpower one
>battery ages after a mere 3 years and still says OK condition in software
>starts rapidly turning PC off and on like a strobe light without failing gracefully
>replacement is a PITA

I have this in my server rack.

>>106145341
Cyberpower has a replacement battery finder tool on their website, I'm sure APC does too.

>>106129491 (OP)
My power never goes out unless my power company decides to do a SURPRISE! restart with no fucking warning. I swear this shit should be illegal. I've got where I save all my work every 3mins because I never know when they're gonna do this shit. One time they did this it fucked up my TV, microwave and caused one of my PC monitors to start showing artifacts.

>>106158188
Most houses are actual 240v split phase.
It's 240v with the neutral tapped from the center of the transformer. You get 240v as measured from both live feeds as a result of the 180 degree phasing and 120v as measured from neutral to one of the other taps.

>>106129491 (OP)
Why no just save multiple copies often?

>>106160321
Get a better one.

>>106129491 (OP)
almost all code editors and other editor type programs from cad to video... have some kind of an auto-save/incremental update system losing a day's work in any situation seems insane to me

>>106129491 (OP)
Unironically what's the point of these in 2025? Isn't failing to save a skill issue or just non-existent today with things like Google autosave? I've had many a power outages, used one of these before, and it made no difference besides my wallet becoming lighter and an extra two minutes to be annoyed that my power went out before my PC shuts down. It's never "saved my electronics" or whatever people claim. Haven't used one since.

>>106162616
do you have a home server?

>>106162640
Nope

>>106162644
then there's little reason to get one.

>>106162691
That's what I'm saying

>>106162698
no, you asked a question and i just answered it

>>106129491 (OP)
I had a power surge three weeks ago and it was no issue to any of my electronics (PC and phone included), except for my microwave's clock resetting. I only have a surge protector (6 AC/2 USB C). No UPS

Getting the breaker tripped by lightning isn't fun.

>>106161194
I had to look for videos on youtube to find a replacement
thanks for nothing, /g/

>>106162867
You need to subscribe to the Gold Memeber service package, to get the Neman Marcus treatment, my uninformed chap.

just use a laptop lmao

>>106141813
Retards not using EXT4.

>>106165521
ext4 just loses data without interrupting the end user

>>106162616
It prevents unnecessary equipment wear from panic parking HDDs and removing power from SMPS under load. In theory neither is supposed to be a problem if you don't do it all the time, but in reality this is often when things decide to break. If you're gigapoorfag living out of a laptop there's no point.

>>106161194
Don't buy OEM branded batteries retard. Literally pissing money away. Find out what size it takes and buy one from a reputable company like CSB or Interstate for less than half the price.

>>106166478
Yes, and you can use a battery finder tool to determine what size the battery is.

>>106166478
>>106166840
Listen to these guys. Battery is battery.

>>106162616
We use journaling file systems and copy-on-write these days so the risks of corrupting files because you lose power during a write (and OSs and modern programs write CONSTANTLY). However typically the file system's response to an incomplete journal entry is to discard it. You think you saved, but the journal entry was never committed. Maybe if you're running linux or BSD you'll be able to google how to view the journal entries and see random blobs of binary shit that might be your data, but you likely won't. So is it worth it for you to avoid losing the last 10 mins worth of work since the last autosave? When it happens to you at the worst possible time, probably.
And that's why we do such things. Because a few hundred bucks with a replacement battery every 2-3 years isn't that big a deal compared to how much money you could lose when you're stuck doing a recovery operation 30mins before a deadline.
Many people use laptops which are basically just better UPSs in practice.

>>106166478
True, but also watch out for scummy sellers. Off brand batteries may be perfectly fine, but only if you're actually buying an off brand battery and not some wanker reselling fakes and recycled trash.

>>106167170
Amazon and Home Depot stock appropriate batteries. Even a zoomer can figure it out.

>>106159751
Got a CyberPower CST150UC-FC
Currently have my NAS plugged in alone and it has estimated 16725 seconds of runtime (around 4 hours), though I really doubt those numbers.
No noticeable noise so far.
Heavy as hell and looks like a tumor on my setup. might get something smaller.
