Hello !
This is my config :
Asus P7H55
Intel Core I3-540
2*2Go Kingston Value
Leadtek GTX 280
Thermaltake Smart SE 530

I used to have a no-name kind of PSU (650 watts) but it finally died on a hot evening, so i ordered a new alim, i figured that 530 watts would be enough as the PSU was rated 87%.

My PC works fine as long i'm not playing any game, but when i launch a game, it will crash and then reboot after 2 or 3 minutes.


I have logged the temps and voltages and nothing seemed to be bad.
My GPU temp was about 85C°, CPU @ ~60C°

I have tried another hardrive with another windows installation but I have got exactly the same problem.

Everything was working perfectly before my noname psu fried.


Someone has any idea of what could be the problem ?


Thansk, have a great day.

it is probably that the computer has to little power since you downgraded from 650 to 530 watts if not its probably the graphics card.
its about 4 years old and may not be able to handle games anymore

Update: I swapped the PSU with a 650 noname one and it still crashes.
I swapped the GTX280 with an old fart 7600GT and it works "fine"

Do you think the gc is dead ? How could i check it ?

No shit sherlock ? Of course it doesn't handle much over the GTX280.
But the pc doesn't crash so i now know the problem is really between my GC and my PSU, but since it doesn't work with any of 2 psu, it looks like it most likely the gc that is faulty.

Update: I test my 280 in a friend's setup with a 700 watts psu and it works fine... So i guess 530 watts (even with 87% of eff.) is not enough !?
