Computer Instantly Shut Down (Power Supply Problem?)

[jaruki12]

Recetly I upgraded my gpu from GT430 to GTX 560 ti.

But sometimes when I'm playing games the computer shut down randomly.
And I can't turn it back on until about 1 hour.

I have a cheap 500w PSU from Cooler Master.

The graphics card required a 500w PSU which mine barely make it and it's not from a quality brand.

BTW currently my case have a quite bad air flow because of the untidy wire.
And my processor can hit 70C when playing games.
I don't know if this temp is normal or not.
I'm afraid it shut down because of the high CPU temp


core 2 quad q6600 2.4 ghz
4gbx2 ram
gtx 560 ti
eXtreme Power Plus 500W PSU

Please read this review: http://www.hardwaresecrets.com/article/728

In the review it states that your power supply is in fact a 450 watts PSU. For the graphics card that you have you need a minimum of 500 watts and a good brand like Corsair, Seasonic, Antec, XFX.

I recommend between 500 watts and 650 watts; good brand. Watch the sales and promos at Newegg.

Allright then so it is my PSU after all. Thanks

Yes; and get a good brand. Sometimes a 650 watts PSU will be on sale for a better price than a 500 watts PSU. Watch for sales and promos.

64-bit
I push the power button and nothing happen. The light on my lcd is also gone. So I suspect it's the PSU
No special game

And as I said this happen after I replace my GPU from GT 430 to GTX 560 ti
