Except that power supply is barely even made to handle 500W, not including efficiency.
Hardwaresecrets says it is capable of delivering very close to the specified wattage, I'm just worried that he's already damaged his components because of the nasty ripple and noise levels in the voltages at loads above 80%.
That is true, but I would feel better recommending something with a better rating. I did have a Extreme Power Plus and ran a 256-bit GTX460, which had 2 6-pins. That being said I did not run it for very long as I was waiting for my Antec NEO power supply to use.
You could use it, but at your own risk. I'm not saying it would blow up or something but still.
thanks guy. i will consider to replace new psu.
a hx 650 is best choice for it it have 52 a and modular which means power efficient
