Computer Turns Off??

post #1 of 7
Thread Starter 
Hey guys!

I have a slight problem with my sig rig. Whenever the computer comes under load, it just turns off. It only happens when there is large explosion in GTA IV or any other game.

The problem first started when I got my GTX 460, this did not happen with my 9800GT. The 460 is overclocked at 825/1650/1825, it doesn't seem to power down if it isn't OC'd.

I am beginning to think that this might be my PSU, it was some cheap dodgy one after all.

If it is the PSU, do you think a Corsair HX650 would be a good one to get?

Thanks in advance.

Check to make sure all your connections are secured and tight. But it does sound like a PSU problem. The 460 draws quite a bit more than the 9800GT. And yes the HX650 is a great PSU.

I doubt its the connections, it has been reseated about 3 or 4 times since January. Thanks for the suggestion though.

I will probably invest in the HX650, I need a modular PSU, cable management in the Thre Hundred is terrible.

Modular definitely comes in handy, makes cable management a lot easier.

Dodgy, yes. Cheap? That's a rip off. Get this. There's no combined +12V rating; but the absolute maximum you could guess would be 30A, which would be typical of a 400W power supply. More likely 20-25A. Meaning you've got a crappy 300W at best.


Just pitch it. 99% chance a quality 400W+ power supply will solve your problems.



Also that is a fake 80PLUS logo, Powercool is not listed on Ecos' website at all.

I agree with Phaedrus. Dump the poc psu and get a quality one and your problems should be solved.
