>PSU mounted on top / bottom
Which is better?

>>105740562 (OP)
Top because heat rises

i would never understand why it would be at the top

Bottom because a good PSU weighs a ton and having a top-heavy case is retarded.

>>105740562 (OP)
Bottom because heat rises.

>>105740562 (OP)
There's a reason modern case design moved to the bottom. You can have bottom intake fans that blow on the video card with with large inlets in the power supply shroud area instead of the bottom of the case with low clearance. You can have a power supply shroud to hide cables and storage. Power supply cables up top get in the way of top exhaust and you can't shroud it if you want top exhaust at all. Also modern power supplies try to use a low fan speed and don't make a better exhaust than a normal top fan that runs as fast as you need it to.

>>105740565
This only matters outside your case to reduce recirculation of expelled air, but it wont matter if your room has poor circulation and the PC is effectively a space heater either way. Inside your case the air is going the direction the fans point it. Stack effect is very slow.

>>105740562 (OP)
sideways
just like the good old 286 days

>>105740567
>>105740599
because the heat coming from your PSU is rising up onto the GPU chipset and making it even hotter than it needs to be. stop being retarded.

>>105740562 (OP)
Power supplies are heavy, it would make your case easier to tip over. A more obvious reason, the hot air from your pc components makes the psu perform worse. Both efficiency and output cleanliness wise.

>>105740810
You mean the heat from your GPU chipset is rising up onto your PSU and making it even hotter than it needs to be.

>>105740562 (OP)
Mine's mounted outside the case

>>105740810
Your PSU has a fan in it and exhausts outside of the case. There is no heat rising from it.

>>105740851
The power supply fan is mostly stopped.
Power supplies only consume 10-20% of the power of the rest of your components generating much less heat.

>>105740565
>Top because heat rises
Correct. The PSU acts as a secondary exhaust fan. It's very efficient. In addition, it sucks hot air directly away from the VRMs. If you are using a down pressure fan then this works extremely well.

Bottom PSU mounting is not very robost. It's good in theory but the air intake is from under the case. This requires case mounts and a gap between the case and the surface it is placed on. Very vulnerable to obstruction just added daintiness to the overall design.

>muh dust covers doe
Pretty bad for thermals actually.

Top PSU with additional dedicated exhaust fan is tried and tested gold standard.

>>105740826
>Power supplies are heavy
You know what's heavier? I big motherfucking metal case. You RGB zoomzooms with your lightweight glass Chinesium greenhouses don't know anything.

>>105740562 (OP)
I wish I kept my high quality top mount case from '09. Had no stupid window either.
The current stuff is either a vacuum cleaner with a window, or a flimsy cheapo tin can finger slicer with bad mount options.

*yawns*
Yeah... whatever...

>>105740567
So its fan acts as one of the exhaust fans, there are pros and cons regarding the solution.
Back in the day on any usual PC setup the PSU fan was the only exhaust fan in the case.

>>105740562 (OP)
Bottom, as heat rises.
You don't want 500W+ of heat being dispersed into the power supply...
Freeing up the top allows for natural exhaust or with fans.

>>105740993
I'd rather have a big metal box that drains 500w and can survive a nuclear blast than a fragile plastic 5w shoebox that crumbles to a loud fart.

Reliable, neverdie technology is a quality from a bygone era that many limp wristed permachildren will never appreciate.

>>105740916
Why would you make your computer perform worse? Put the power supply at the bottom and feed it cold air. Not only will your components get cleaner current, your power bill will be lower.

>>105741019
>You don't want 500W+ of heat being dispersed into the power supply...
Actually you do. PSUs can handle the heat just fine.

>>105740562 (OP)
Why the fuck would you ever want it at the top other than because it used to be that way? It just sucks up dust along with the hot air from the rest of the parts.

>>105741032
read any psu review with hotbox testing
sounds like you don't even have a computer and you're just here to argue

>>105741026
>Why would you make your computer perform worse?
Why do you use a case at all then?

>>105741032
If you want to risk it then go ahead.
Having it at the bottom means it pulls in cool air and the rest of the components have extra exhaust at the top of the case. So a cooler, quieter, more efficient system..
You are just contrarian.

>>105741047
Sucking air from under the case is retarded. It means you need to put your computer on legs. That's dainty and gay.

>>105740875
Then it isn't generating much heat.

>>105741047
>If you want to risk it then go ahead.
See this is the problem. Computer parts shouldn't need to be treated like fine china that can break and fail so easily. Bottom PSU mounting embodies the attitude of fragility. Top mounted PSU embodies robust and knockaround construction.

>>105741082
In this case a top mounted psu would assist in removing heat from your VRMs, wheres a bottom PSU does nothing for your overall system thermals.

>>105741054
So just flip the power supply? It just sucks away air from the GPU instead.
>>105741076
Okay but even still, having more (and natural) exhaust points is far more beneficial anyway.

>>105741099
>It just sucks away air from the GPU instead
Sucks from the wrong direction sorry. Remember FPBP.

Mr Stockton Crush, please do not buff out the wrinkles in your carbon fiber wrap.

>>105741113
Nah this is just rage bait. Nobody can be this stupid.

>>105741122
It's a fact that it's less efficient the suck heat from below.

top like in the original ATX spec

>>105740562 (OP)
Top-front

>>105740562 (OP)
Bottom because the PSU is heavy and it keeps the cable out of the way.

the vrm is taken care of by the rear and top 140mm exhaust fans

>using my DNS server as a daily drive desktop
Why would you do this to yourself?

>>105740562 (OP)
Any decent modern case has the PSU isolated from the main compartment and drawing air in from outside directly. It's a solved issue unless you're a dirt poor turd worlder.

>>105740562 (OP)
Doesn't really matter since every design I've come across vents outside the case. Some pull air from in the case and vent that out and others pull their air from outside. I guess bottom would be better for keeping the center of gravity lower though.

>>105741876
>4000 fans
The top mounted PSU fan is the most efficient solution. Just citing the ability to add more fans to everything is a silly cope.

>>105742610
no it isn't as explained multiple times in this thread

>>105740993
Poor excuse of a computer even compared to a laptop.

>>105740562 (OP)
Neither, use a rack chassis like a man

>>105741099
>just flip the power supply? It just sucks away air from the GPU instead.
GPU fans are pushing air up. Trying to pull air in the opposite direction will do absolutely nothing. This is why top mounted psu is great, it's a free exhaust fan which actually helps overall system thermals.

I remember being about 19 with my first gaming PC and it had bottom mount PSU. I put it right onto my carpet floor..

Top so it doesn't have to pump electricity against gravity.

>>105741571
that looks like one of those inside-out cube optical illusion

Top, so when water leaks from my AIO there isn't a Hiroshima bomb going off in my bedroom where I keep my anime figurines.

>>105740565
Right into the PSU, yes

>>105740562 (OP)
why not in the middle? best of both worlds.

top because gravity helps the electron flow

>>105741697
that's a clean build

>>105742805
why do you have an AIO? Heatsinks are better at this point

>>105743009
Cooler and quieter.
Cheaper than Noctua but Thermalright is cheaper

>>105743106
I do appreciate AIO but they're only cheaper if you don't consider rebuy, maintenance and risk.

>>105740562 (OP)
outside the case obviously.

>>105740875
You defeated your own premise. But even if I ignored that, you'd still be wrong. You can choose for the PSU fan to always be on. That's usually a button that you have on the PSU.

bottom front, fan removed, no gay enclosures

>>105742895
>heat magically avoids the middle rear exhaust fan and goes straight into the psu
retard

>>105744862
I'm not the guy feeding my psu hot air

Bottom. It's relatively heavy and lowers CGI.

>>105741697
this shit looks so fucking gay.

>>105740562 (OP)
I want my PSU at the top because I dont want the PSU fan vacuuming all the dust and dog hair from the floor into my PC.
But everyone else in this thread should have their PSU at the bottom because you're faggots.

I recommend putting it where the motherboard has the correct screw holes. Otherwise, it may get in the way of other components.

The best option is mounting it externally, to keep the heat away.
