HI guys, just looking for a bit of help on my rebuild, im not sure what size PSU i need.
im not doing a full upgrade just PSU, GPU, a new case and possably water cooling or a few fans.

Just need help on the PSU Guys, just take in mind i may go SLI in the near future.

Much appreciated in advance for your help

instead of the 550, get a 5770/6770, they are cheaper, perform the same and use less power. For the psu get a 500w+ unit from Antec, Corsair, Seasonic, XFX, OCZ or PC power and cooling. Dont go with unknown brands unless you find a good proper review of it.

Yep, 500 would be plenty. You could run on an Antec 380, but it wouldn't be efficient, as PSUs lose efficiency toward the top of their load capacities.
