then why did my friends Kill o Watt meter just now read 436 watts. i started dirt 3 after we hooked it up and thats what it read right before it shut down. you have to take into account my drives, mobo, and case cooling/lighting. i know my current psu wont actually put out 500w, obviously it won cause it shut down at 436. really 300 watt to power an oc'ed quad core and two oc'ed 6770's i think your math is a bit off. my cpu pulls atleast half of that 300 watts when oc'ed i'm gonna stick with my previous decision to go a little overkill with a 750w. if it pulls that much with just one card i want to play it pretty safe when i get my second card i know my system will only use at most 550 watts at a full load not even that while gaming. but having a 750 enables me to do future upgrades as well. plus this is still my daily use system my new i7 system is mostly for testing purposes only.

Maybe because you're running a ~250W PSU with ~60% efficiency at full load!?.. Think!!

Read my post again, I was refering to your current system, and as far as I understand from your posts the CFX setup is a future project.

did some reaserch on the psu that is in it. it is supposed to be 85% efficient thats not an in house rating either otherwise i wouldnt trust it

i apologize for the mishap but even at 15% points lower it is still pulling over 300 watts true pull off my system. i understand you are just trying to help but i'm just gonna trust my gut on this one.

Trust your gut.750w with most of them on a single 12v rail would be my suggestion.

Please give the exact product name/code on the PSU.

found the problem that causes it to shut down . its only got 22amps on the single 12v rail. 40amps on 5v and 30amps on 3.3v. that makes no sense but i guess they added amps to the lower volts just to get it to 500w. 22a is about equal to what a 350w psu should be(correct me if i am wrong) so i stand corrected i dont need more than 500w but hey i got a 750 so i know i can upgrade for a while. also the model number is ky600atx, it's a rebranded winsys(yikes). it is supposed to be 85% efficient at full load.

So much power on the 5v and 3.3v rails indicate a very old design meant for computers from over a decade ago when more components ran on those voltages. But yeah for modern computers it really is only a 350 watt PSU at best.
