Corsair HX850
Reviewed by Keith B. Review Posted 01/08/2012
Excellent quality PSU, by far the best I've ever used. I expect no less from Corsair of course. One of the excellent features of this PSU is the semi-modular setup. Built into the PSU are 24 pin ATX, 2 x PCIe 6+2 pin connections and an 8 pin CPU power cable, all of which are delicately sleeved. The clutter of unused cables is a thing of the past. Also Corsair provide a plentiful supply of modular cables too. At 80+ Silver, Corsair guarantee maximum efficiency from this unit at most load percentages. Top class purchase!

Brilliant PSU
Reviewed by John Kenny. Review Posted 21/10/2009
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.

Excellent PSU
Reviewed by Martin Heelis. Review Posted 29/05/2012
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.
