PSU gonna die?

post #1 of 13
Thread Starter 
Hi all, I've been monitoring my temperatures recently and I noticed something I didn't expect when looking at HWMonitor:


My 12V min is listed at 11.62, this seems awfully low doesn't it? These temps and voltages are after playing Crysis for about 2 hours. I was thinking about getting a modular power supply anyway when I upgrade to a Phenom II 940 in April, do you guys think this is a necessity now? Any opinions or suggestions would be great.

Might have just dipped for a few seconds. You are kinda pushing it with two 9800GT SLI and a overclock 6000X2, she will be fine i recond just watch it.

I don't think it matters how stable the voltage is as long as it continues to supply enough power to your components (I would say definitively with watts=amps*volts but I'm not great with electricity). Seeing that you didn't completely crash out, your PSU seems to be supplying enough power. Either way, I'd recommend this Corsair for active PFC (power factor correction).

edit: that 650w might not cut it
here's the 750w and 850w as well. great psu's

Software can't read out those voltages precisely. You'd have to use a multimeter or something like that.

I was thinking about getting a ~750w. However, I'd like to go modular as it'll help out my cable management quite a bit. Do you guys think that I'll be fine until early April (running this machine about ~10 hours a day), or should I upgrade sooner? Any suggestions on a nice modular PSU would be appreciated.

Edit: Also, any time I stress with Orthos or Prime, my 12V never gets below about 11.9. Could it be that during peak load times, my video cards are using too much power?

Don't trust software voltage monitoring. It's really inaccurate. You'll need a multimeter to actually test the 12v rail.

Ok, now regardless of the absolute accuracy of the program, I just played Fallout 3 for about an hour and a half, and now the +12V had a min of 11.26V. This seems way low, could anyone comment as to if I need a new PSU or if it can wait for a couple months? Thinking maybe a ~750W, but with my current 550W is it being stressed too much?

Looking for a modular PSU, price not extremely important but I don't want to drop more than $175 at the most. +Rep for helpful comments.

A Corsair HX620 could power that rig just fine, it's modular too.

I'm getting a Phenom II 940 and planning on overclocking to the limits.. do you think this would change anything? I wouldn't mind getting a larger power supply so I have extra space in the future for upgrades, do you think I should get a new PSU with the Phenom II in 2 months, or soon? Having a (supposed) dip to 11.26V is worrying, and if there's a chance that it could fry something, I wouldn't want to risk it.
