My computer switches off during benchmarks =(

post #1 of 34
Thread Starter 
Hello , i have myself a 6950 flashed to 6970 . In some benchmarks when overclocked 920/1400 my computer will just turn off like i pressed the power switch .. Now im assuming my 665w generic psu cant take the beating im giving it with all my components and my cpu overclock ... Would it be wise to get myself a new psu ? do you think it would solve my problem ?

This is my psu , it claims to be 665w but it says max is 550w
http://www.jw.com.au/widetech-650w-s...t-pci-ex-p-674

At default settings , it runs fine but a little overclock and my whole computer turns off :s i dont understand .

Help please , rep given .



full load i think my cpu does 192w + 270w+ for the gpu .. that doesnt leave much for the rest of the compnents i have .. all the fans , leds etcc

Because your computer shuts off ONLY during stress testing, AND it shuts right off, I'm sure this points to your PSU. You don't have visual anomalies on screen, and it only happens during stress test.

As you said yourself, it's a generic, so it most likely doesn't put out enough amps on it's 12v rail.

As for a new PSU suggestion, I would recommend any Corsair, SeaSonic, XFX, or Antec PSU in the 600 - 650w range, just to give yourself some headroom for future Crossfire / overclocking.

Also, I wouldn't trust the software voltage readings. The only true way to tell your power draw is with a volt meter.

Again, sounds like 100% the PSU is shutting off due to over current protection.

Assuming your overclocks are stable and nothing is overheating, i'm fairly confidant that your psu is to blame. I've lost count of the number of generic psus that have been professionally reviewed and found to be able to only supply half of their rated wattage.

That PSU is a piece of crap.


Got a budget for a replacement? You only need a quality 550W at most--yours is probably a 300W or less.

It sounds like the PSU hits it overcurrent protection and shuts off. You are probably only getting 300W max out of that PSU.

You should probably buy at least a 500W PSU for your rig. 550W should be more than enough. Get a good brand/model too.

Intel burn test says im fully stable at 4.2ghz under 75c load so that isnt the problem ..

it only cost me $60 i think for the psu , money isnt an issue i think ill go buy a decent $150+ psu for my rig .. My psu is the cheapest thing in my case and i admit i have alot of things running off it uncluding the push fan on my h50 overvolted to either 17 or 24v not too sure .. whatever the blue - wire is on the 24pin

Thank goodness it's shutting off and not taking your components with it to the grave. Seasonic, Corsair, Antec, any reputable manufacturer with at least 500W will be a good place to start.
