Best way to test my PSU?

Barso · 3 May 2010 at 23:05

I have a gtx295 and an EVGA classified MB running a cori7 920.
My PSU is a tagan 1100w piperock.
But I think I may be having problems running the GTX295.
Is there anyway to test my PSU and make sure it's supplying enough volts?
Thanks.

I'm no expert but I believe the GTX 295 uses about 300 Watts at 100% load.
300 watts on 12 volt rail is: 300/12 = 25 amps

I'm assuming that your PSU has multiple 12 volt rails with 20 amps on each?
That may not be enough, each component can only draw power from 1 rail (I think?).
I think that's why people prefer to go for PSU's with single 12 volt rails.

This is just my guess though... I may be completely wrong :confused:

Assuming there are is no fault, that PSU should be more than capable of runing pretty much any PC running pretty much any graphics card. 2x295's in SLI might be pushing it, but apart from that you shouldn't need to worry.

What is the rest of your system spec? what issues are you having?

I am having really bad sound skipping and framerate stuttering in crysis 64bit.
32bit runs fine but not 64bit.
Thanks for the help.

Possibly a driver issue, especially as it runs fine in 32bit.
All drivers up-to date.

What is your full pc spec.

I would be inclined to agree, do you get this issue with other games? if not then its either drivers or that particular game - Crysis whilst impressive, is not the most polished software ever produced.
