Hi, I want to buy a second radeon hd 5870 for crossfire, but I'm not sure if my power supply is enough, here are my current specs:

AMD Phenom ii x4 965 3.4 ghz (might overclock)

XFX Radeon HD 5870

ASUS Crosshair iv formula

WD Caviar Black 1Tb 64MB cache dual proc harddrive

2 dvd drives, dont know model lol

XFX Black Edition P1-750B-CAG9 750W CrossFire Ready 80 PLUS SILVER Certified Power Supply

is 750w enough? I also might overclock the graphics cards as well, here are links to power supply and graphics card:

Yes it can power two 5870s.

The newegg calculator is retarded; if you add a GTX 460 it adds 200 watts when it only consumes 160/150 watts.

the newegg psu calc is total BS. as are all psu calculators.
a high quality unit like an XFX will have no problem with those two graphics cards, even though its only 750w!
