PSU at top or bottom - Page 2

post #11 of 25
Yeah it can be quite a reach. I managed to get all the cables neatly in place in my 900 though a full tower could possibly have made my life harder. The other nice thing about bottom PSU is that it's cooler down there.

Well the case is only a mid-tower. I like the idea of keeping the PSU farther away from the CPU area, and I can mount an extra fan to the top of the case if the PSU is at the bottom...
I'm leaning more towards bottom .
edit: what about having the PSU at the bottom but flipping the motherboard?

Well, flipping the motherboard would force you to think out a new I/O location and expansion slots as well. I had a look at your Acrylic case and to me it looks like a fulltower or something in between?
I'm all about bottom mounted PSU's since they don't get in the way of hot air rising inside the case. Yes it can be a difficult reach for your cables but open the right holes and there shouldnt be any big problems. If it does, extend.
Since youre building the case from scratch my bet would be to just decide on what location and work my way from there. Your creation looks promising nonetheless.

Depending on the type of PSU, at the bottom you also have the option of drawing in air from under the case venting it out the rear. Thus eliminating most the heat from the PSU in the case.

the only reason to put the PSU LOW (IMO) is to conserve space and at that moment I place the PSU down and front. good for space and cable management but otherwise its good to have it up high. It helps with hot air exhaust.

Alright thanks guys, it's decided.
Bottom!
I can extend if I need to .

Bottom is the best for the PSU. It won't have to exhaust any of the hot air rising in the case and thus would operate at lower temperatures, increasing it's life span and improving performance. But as others have said, cable length may be an issue unless you go with a reverse-atx setup (like some Lian-li cases).

yeah I'm still debating going reverse atx. I haven't made any cuts into the acrylic pieces yet (just getting them sized perfectly still) so I can change my mind, until I start cutting.
Do some motherboards have an issue running upside down? I remember reading a few years ago that some just wouldn't work (it may have been a heat-pipe issue though).

Yeah, it's a heatpipe situation. I know some heatpipe designs don't like working in certain configurations, but I would guess that heatpipes on mobos are designed to work no matter the orientation.

Be sure to put a filter under your PSU intake fan if you're drawing from under the computer. There's a lot of crap that can get sucked up through a bottom-feeding fan. Gunk and dust are bad for PSU temps.
