specs -

AMD Phenom II x4 3.2ghz

ATI Radeon HD 6850 1gb

8gb ddr3

500 watt power supply

I just ordered another HD 6850 to put in crossfire and a new hard drive.. will my 500w supply be sufficient or should i invest in a new one?

Usually for 2 GPU minimum should be 750W... I may be and surely get corrected soon. But I strongly think that it's 750W minimum for 2 GPUs.

Please take this to the hardware forum.

Thank you.

(also yes, for crossfire you'll need 750+ watts)
