power supply:500w super flower with +12v rating of 30a.

In asus pc probe at idling it give 11.07v on +12v rail & while gaming it goes down to 10.7ish the lowest it went was 10.31.

I experience crashes in crysis but strangely in directx 10 mode only & also bioshock-But I believe that has to do with virtual memory issues in 32 bit os & bioshock needs a patch.

I need to know is whether the power supply is contributing to my problems in anyway?

This is how crysis(directx10) & bioshock crash:

Going strong--loking good-5minutes later-screen lockup but game audio in loop-release-running again-rinse repeat 2 times-then...mega crash-ctrl + alt+del dont work-hit reset.

The software programs doesn't always give the correct values. The BIOS should give a more accurate reading as per slicessoul's suggestion.

I checked my voltage in bios:

vcore voltage: 1.24v
memory voltage:1.87v
1.2v HT voltage:1.24v
MB voltage:1.23v
Sb voltage:1.52v
CPU VTT voltage: 1.26v
DDr2 termination voltage:0.94v
3.3v voltage: 3.18v
5v voltage: 4.78v
12v voltage: 11.07v

is it bad?

30A 12V rail Recomended 30 to 32A, bottom of range but should work,
check the voltages in BIOS.

I see you did, 11V is low doesn' look good.

My guess, and this is just a guess, that is a low quality PSU.

Thanks for the heads up you guys I am goint to get a thermaltake toughpower 750w.which gives 60a total through 4 +12v rails.

Lets say I add another gtx later on,will it hold? or do I rather get the 850 watt thermal take which gives 62a through 4 +12vrails? it will cost me 30$ extra though(for just 2 amps) & I am a bit tight on cash these days.Is it worth it?

Thanks a lot once again you guys.

The 750w would be more than fine. You would be getting 24watts more on the 12v rail if your went with the 850watt.

okay-more trouble of sorts

I got the 750w thermaltake

when I had it up & running: iget this voltages in bios & probe:


3.3v-3.20
5.50-4.76
12.0-11.46

But it stays the same even in load.I decided to run 3dmark & to my surprise my avg score jumped by over 400 points :s

update:
i did two changes-
1)Used the sata power connector to power my drive instead of the 4pin connector.
2)Use the thick power cable that came with thermaltake.

Changes:
3.3v-3.23
5v-4.95
12v-11.58

Did I crysis run-normally it crashes when you get to aztec-recovers & crashes 3minutes later(always done that)

*drumrolls*

Yeh baby!!!!!!!-it kept going woot!-bye bye crashes.
