Best PSU Ive had, was recomended this range for HD 4870 Xfire config. The single 12v rail is the key. even has extra capacity 4 another 4870.

If you are thinking of SLI or XFIRE then this is the perfect solution.

Good PSU with tons of cables. The only gripe I have is that there should be a couple of cables with a 90 degree angle PCI Express connector (I had to remove my side fan to fit my graphics card). Due to the increasing size of graphics cards this is a bit of a let down so I knocked 1 of the overall rating.
