with a budget of £35 to £55, what PSU`s are SLI compliant and good for 2X 7800GT ? its not for me and ive never used SLI so i have no clue...

I'd certainly spend a bit more than that if I was going to be getting a PSU for an SLI rig. You'd struggle to get anything in that range that would definitely be powerful and stable enough for two 7800gt's.

If you can stretch to £62, the Hiper Type-R 580 watt should be fine. I think there's a few people here runnings SLI setups on it with no problems. The Enermax Liberty 400W for £50 also claims to be SLI compliant but I'm not sure if 400 watts would be enough.

+1 for the Hiper, great value for money. :cool:

well a 400 Watt PSU will do, i just wasnt sure about the brand. many people go out and buy 500+ watt PSU`s not realising that they will never use that much... for example

opteron 148 CPU
2X 7800GT
2 X opticle drives
2 X 80mm fans
4 X DDR sticks

peak usage is only 397 Watts.
