Case with power supply at the base?

souljas · Post by **souljas** » Thu May 08, 2008 10:55 am

Hi, I was wondering if anyone knew of any other cases (normal size) which have the PSU located at the base of the case? I have seen the Antec P182 and actually really like it, but it is a little too high for me as it will be in an enclosed space. If anyone knows any other gimme a shout.
Thanks

That Lian Li is quite deep and not as short as you'd think. After seeing that I went looking for a similar design in microATX with fewer drive bays (that'd allow it to be shorter) and didn't find anything. Nothing with a 12cm fan, anyway.

Most Lian Li designs use the power supply in the base.

The P18x seems about average height for an ATX case. Are you looking for a micro-ATX case for space issues?

If so then there's the CoolerMaster Centurion 541. The PSU is at the top of the case but the motherboard is inverted BTX style, so technically it's at the bottom of the motherboard.

Hi guys..thanks very much for your suggestions!

I looked at the Lian Li PC-A05B but it was a little too deep for my needs as the comp wont fit in the metal tower holder without sticking out, plus im a bit unsure about the backwards cooling?
psyopper- yeah I kind of need a midi ATX about: 20x42x50, and the P18s are a little tall, I looked at more coolermasters after looking at the centurion and found this : Coolermaster CM-590 Case Plus CM eXtreme 500W PSU

it is just about the right size, with 120 fans, and bottom PSU!

It's even deeper than the Lian Li

the new antec 500 or 400 or 600 or whatever number it is is a copy of the 590

Coolermaster 690 also has PSU at bottom. Both 590 and 690 are supposed to use 120mm fan PSU which should face downward to suck air from hole in the bottom of the case. Although I'm not sure if there is any filter included there.

Antec Three Hundred has PSU below aswell..

thanks for your input guys... I found a better case than the coolermaster IMO : its the ANTEC mini P180.

Looks like a very solid build, quite small, and lots of cooling...here is a link to SPCR http://www.silentpcreview.com/article810-page5.html

From the picture the reviewer used the ninja but didnt cool it with a fan, but the back external case fan is so close to the ninja that maybe there is no need? anyone know if that cooling of the ninja would be sufficient to run a relatively intensive CPU?

Plese define "relatively intensive CPU" ?

edit: in the review mike used

Intel Pentium D 950 Presler core. Rated TDP is 130W. Under CPUBurn x2 load, we measured 78W DC draw through the AUX12V socket, which includes efficiency losses in the VRMs.

That CPU is quite hot. with 200+120 fans right there its probably gonna be good with todays CPUs.

thanks for the reply...how does this setup sound:

Antec Mini P180 MATX Case

Scythe Ninja-PLUS Rev B

Corsair VX450WUK 450W PSU

2 x Scythe S-Flex 120mm Case Fan - 800RPM

AMD Athlon 64 X2 5200+ Socket AM2 (2.7GHz)

Will this processor be too hot for the ninja with just 2 fans? I am going to cover up the top 200mm fan and just use the back fan as the exhaust

This is a perhaps wayward question for this forum, alas I dont know where else to ask where someone might know the answer:

Is it possible that putting a PSU on the other bottom side of the motherboard might cause unexpected exposure to EMI and such and thereby cause problems? Foremost I am thinking about noise in audio output if you have a PCI soundcard directly above the PSU.

That's why real PSUs have metal casing...
Unlike junks like these which radiate EMI regardless where they are.

Tell you what..... configure all your computer components to draw <200W, and you can stick a PICO in there as the PSU. That way you can use any case you can find without even considering the location of the PSU.

With current relatively low power CPUs, and the avoidance of hi-power graphics, a computer drawing less than 200W is easy.

Hehe.. woohaa. One could think that the market for internal computer components focus on elderly women with weird sense of color.

Anyhow.. I was thinking about 120mm fan PSUs. That makes a big hole where EMI get out. Shouldent think it would be a problem but one never know.

You can have a metal barrier between a bottom PSU and the motherboard area.

Artic Cooling made a case with the PSU in the bottom front and the fans inboard-blowing exhaust out the floor via the PSU weith the intake in the rear.

If you are gonna use 2 case fans....and have a 200 mm..use it and just 1 120. At equal RPM the 200 moves more air...or moves equal air at LESS rpm. You get more efficiency with 2 fans in exhaust ( or 2 as intake) than 1 of each. Let the frontal intakes be passive inlets

EMI tends to be an issue with generic "no name PSU's. Most good brands...and I don't nessicerily mean deluxe-expensive,are sheilded well.

Overclocker overkill? I'm not a gamer but it seems the current CPU's....stock...have more performance than the "Extreme OC" of just a few years ago. Is it worth it to squeeze that last little bit out? A very OC'd CPU and "extreme" Vid card can put out WAY more heat. Where's the sweet spot?

I want a 180 mph dragster that gets real good gas mileage and is quiet....oh yeah,I'm on a low budget. Sorry....but there's tradeoffs.
OC everything till it glows and you need FAN RPMs to keep it from burning up. You can do a MILD OC and use a very efficient BIG cooler,have big slow fans,use all the silent PC tricks and have a VERY powerful-but rather quiet puter.
