This is a pretty nice unit-

It has all your specifications, fits the price, and is more than capable. It's not modular, but hardwired PSUs are better anyway.

6850 hd needs 550 watts i have one, and ni general when looking for apsu you look at the wattage the graphics card needs and add 100 watts and psu's degrade over time.

i have this for my 1055t, 4 gigs of ram, and xfx 6850 hd:

has every connector under the sun including 24 pin mobo, 8 pin cpu, 2 x 6/8pin pci e, 8x molex, 8x sata. so everythign you need and more i can highly recommend this psu probabably the best i have ever owned just make sure you have a spare empty couple of drive bays to fit the spare cables
