>even when idle, a UPS wastes energy
A UPS isn't just a battery; it's an AC > DC > AC converter running all the time. This conversion is never 100% efficient. Typical small UPS units run at 85-95% efficiency in "online" mode. That means if you plug in a device that draws 100 W, the UPS might draw 105-115 W from the wall just to feed it. That extra 5-15% is pure heat loss, and you’re paying for it.

So what I'm not a third worlder I literally set off my dishwasher on maximum heat program just to wash 1 plate and a fork sometimes and dont give a shit.

then you'll be a fucking homosexual in tech

>>106194880 (OP)
Most big UPSs are not inline but use a transfer switch. So you only lose a bit of energy and its a constant and not scaled with the load

Not all the time, only while charging. Shut the fuck up, retard.

>>106194880 (OP)
So the average PC runs 3-500W when in use, 10% loss for 15 hours a day, 30 days a month is 18Kw of electricity "wasted". My average bill is ~400Kw a month. So I add 5% to my power bill to ensure that my ~4-5k$ pc and peripherals are safe from random voltage spikes and in the case of a power outage I can save what I'm working on.
At this point I expect you to tell me you rush in and out of the shower to save on your hot water bill...

You can tell turdies are the majority on this board now when we have threads about how using like $5 of power a month extra is the end of the world. even an extra $100 a month on my power bill would make fuck all difference to me. If $5-$200 is a lot of money to you maybe stop worrying about computers and fix your life

>>106195281
if you're getting such critical voltage spikes, it might be a better investment in the long run to fix/improve your electrical wiring and prevent spikes in the first place

>>106195229
Depends on the unit.
More expensive ones tend to be ac > dc > ac because there is no failover time. The power is always coming from the battery dc > ac circuit so when the main drops it is completely unaffected.
Cheaper models will failover, and if the load is a little high, or the failover time is a little long, or the device is very sensitive (cheaper power supplies) then it can still cause the device to restart/crash.

>>106195634
Not that guy, but my UPS is 99% efficient and charges battery in intervals to preserve lifespan.

The majority of them *do not* work this way.

>>106195281
I don't know why normgroids believe that by saving a few goybuxx on leccy they will improve their lives in any way that matters. They're niggers who have to wagecuck for 50 fucking years because they lack connections and were doomed from the start so why the fuck care about a 5% higher leccy bill it's so insane. These gorilla niggers fell for the "work hard and invest" insanity that the psychopathic elites are throwing to the masses like dog treats, it's like they think that 1 goybuxx they saved by not washing their buttholes is going to make them billionaires just like bill gates or bezos or musk

>>106194880 (OP)
People globally waste far more electricity on wireless phone charging, which has no actual utility unlike a UPS. If you're gonna complain about wasted energy, complain about that instead.

>>106196068

It lets me charge my phone with a broken USB port.

>>106194880 (OP)
>it's an AC > DC > AC converter running all the time
nah. lots of entry level UPSes have relays that switch mains directly to the outlets, only breaking the connection when power fluctuations are detected. Gay retard

>>106194880 (OP)
The PSU in your PC does the same so the loss is more like 7-22%
It's fucking over for UPS cucks

>>106196728
Use case for not fixing your phone?

>>106194880 (OP)
A small price to pay to protect against brownouts and blackouts. Nothing's 100% efficient, that's a given.

Why would my UPS be idle you fucking retard? If everything that is attached to it is shut down then the UPS can also be shut down

>>106194880 (OP)
More than worth it for when the power flickers thanks to another fucking storm.

>>106197524
Your PC PSU does not do AC to DC to AC.
Only AC to DC.

>>106194894
Based
Same, not my problem

>>106194894
Only third worlders can afford that these days.

>>106195647
Tell me more about charging in intervals.
As a ups, it's entire task is to be there when the power has an unplanned failure.
Due to the nature of unplanned failures, anything less than 100% charge all the time is unacceptable I think. Unless you have regular scheduled time where the protected equipment is off, like at night, then you can do it then I guess

>>106194880 (OP)
Only expensive "online" ones, most consumer ones just switch power with relays, power draw when not in use is negligible.

>>106199696
Corporate-tier UPS come with all kinds of fancy software features that let you run automated tests, scheduled charging, outlet control, etc. It looks something like this.

>>106194880 (OP)
No even my 14kwh house battery is switched. There's a measurable drop when it kicks in and lights will flicker. Most electronics will survive the flip.

>>106199696
>Tell me more about charging in intervals.

Batteries are not technology. You want me to get banned, faggot?

You know what the difference in my power bill is when I run my PCs 24/7 compiling software and encoding video all of the time vs. turning them off at night while I sleep?

About $2 a month.

>>106194894
one plate and fork can be cleaned in the sink in matter of seconds.. vs waiting 30minutes minimum for a dishwasher (mostly like two hours or some shit)

>>106201753
the program is 2 hours and 45 minutes

>it's an AC > DC > AC converter running all the time.

This is only for dual-conversion UPSes that are expensive and generally pointless for home.

>>106194880 (OP)

maybe so but as landline is fuseless i want system as cold as possible there might be some charge in psu caps but you know what a cap is if you ever open anything

>>106200125

I just lost.

>>106194880 (OP)
everyone knows this but nobody cares. people don't buy a ups to save money but to have an uninterrupted supply of power in exchange for some money.

You know what's the fun part? PCs don't need AC, you could connect a 100V battery to the (modern) PSU and it would work just fine.

It's almost like doing work requires energy. My mind is truly blown Original Poster.

>This conversion is never 100% efficient
It's literally 50% efficient you dumbass do you understand what a rectifier does lmao!

>>106202162
>100V battery

The vast majority of ups affordable for a home user are line-interactive. Which means the inverter is only in play during power outages. Online is pretty dumb for home use in general.

>>106202378
8 12V

>>106195222
you brought up being a faggot first though (you said turdie)
>>106194880 (OP)
only fancy ones do that. The cheap ones are on AC and switch when outage.

>>106194894
Same

>>106202526
This man knows what he's talking about. The time it takes for the UPS to switch between AC and battery is short enough to not cause any damage to your PC anyway.

>>106194880 (OP)

Europeans afford a home AC, let alone a washing machine, or a UPS.

175K Europeans die due to not having access to AC

euros might have bolt on ac but they have no idea how to instal

Moved to South East Asia and my electricity bill is so fucking low, paying 4c/kwh

>The man who sleeps with a machete is a fool every night but one
same case for using a UPS, all it takes is that one time where a UPS saves you from a preventable catastrophic failure for you to believe in one

>>106207750
175K death annually suggests Euros cant afford it. We know Euros are half as poor as America, so its to be expected. But this number is still staggering. 175K each year in death due to heat is like dropping both nukes in Japan each year in Europe.

>>106194880 (OP)
So? I didn't buy a UPS out of some delusion that its more efficient than plugging into the wall, I bought a UPS because it adds a layer of reliability and keeps me from losing crucial data. 100% worth it.

>>106207813
>from a preventable catastrophic failure
What failure?
>oh no, I have to restart my pc to post on 4chan

>>106199696
>anything less than 100% charge all the time is unacceptable I think.
I disagree.
Critical system should have a generator with at least a month's worth of fuel.
The UPS only needs to power the system for a few seconds until the generators kick in.

I use a UPS with my NAS to allow it to shut down gracefully, it only needs to power my NAS for 5 minutes.

Relying on batteries to keep a system up during an outage is dumb.
But even then a healthy battery at 90% charge is better than a "fully charged" degraded battery that can only store half its original charge.
You're likely also going to forget to replace your UPS in time so when the battery dies after 2 years of continuous charging you're completely unprotected.

>>106207832
Only old people die from heat.
It's often what pushes them over the edge when they're about to die within months anyways.

And air conditioners at elderly homes do more harm than good.
They make the air dry which causes a lot of airways infections.
That's why we don't use them in mild climates, not because we can't afford them.

What is it with Euros and always wanting to rationalize their way into living in discomfort and inconvenience? I have family that moved to Europe and their experience was like

>why is there no air conditioning
>well, because the houses are old and units won't fit in the windows. Plus electricity is expensive. Just crack a window!
>no, the windows don't have screens, we don't really get bugs anyway
>i mean there aren't that many bugs
>i mean really bugs in your house aren't really a problem

She ended up basically stapling mosquito netting around the window at her apartment lol

power interruptions during a critical system update is one at the top of my head
