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.
I upgraded cpu and motherbord a few months back so i will leave that as is.
Here is the full system when done.

Motherboard : Asus m4a78lt-m
CPU : AMD Phenom ii X6 1090t Am3 (983) with CoolerMaster V10 Heatpipe CPU/Memory Cooler
GPU : Nvidia GeForce GTX 550 Ti 1GB
Case : ThermalTake Chaser MK-I with 4 200mm fans and 2 140mm fans
PSU : ??????????????????
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.
