Power supply for 6770

[miladpourkhorshidy]

Hi Guys, I had created another topic before but I didn't get the answer. I have reached to several guesses, Manufacturer site says the psu should be 450 W minimum But i had 380w psu. I had green and red dots when I started windows after a while since i had shut it down and when the pc was cool On my desktop and other programs. After a while they dissapeared. I brought my pc back to the Store which i had upgraded it there and he said he would test it with another psu. What do u think? Can it be the problem ??

Yes the PSU can be a problem. If the PSU is a cheap one, than he can't deliver those 380W because in most these cheap brands eficiency is lower than 80%.

A Corsair 530w PSU is good enough
