Computer shutting off when gaming?

post #1 of 56
Thread Starter 
I just purchased a GTX 480 and tried to play any game with it without success. The power shuts off the whole computer and it restarts. I checked to make sure my PSU was good for it and it is, it's 650w with 42 amps on the 12v rail. any ideas?

What is the make and model of your PSU?

What GPU did you have in your machine before

Can you please fill out your system spec's in the user CP

Thanks

If you have had that PSU for awhile, the capacitors have most likely degraded and the max power of the PSU is too low to support that card. How old is the PSU? Brand?

Why are you immediately blaming this on his PSU?

It's my opinion. You have your own.

Do you have enough airflow in your case? I believe the 480 series are known to produce quite a bit of heat, and that might be causing the other components to also heat up by quite a bit without the proper airflow.

Based on the symptoms.

If he had an ATI card in there previously it's a well known fact that old ATI drivers and Nvidia drivers conflict and cause these sorts of issues.

In short, until we get more information we can't pin point the issue.

most of the time it is the psu.
what brand?

it might be temps that will auto shut off.
(we need to know specs like what case u have and number of fans.)
bad cases will build up heat and at over 100c(around there) it'll auto shut off to protect itself.

It seems to me that when he tries to run a game, the computer restarts, which is a pretty good indicator that the PSU can't handle the power requirement.
