Have you considered GTX470SLI instead?
You probably only need a decent 750W/850W PSU with overclocking included, and the GTX470 price to performance ratio is better![]()
Thanks. And if I did you 480 SLI then I would need around 1000W aye?I have narrowed my choice down to either the Corsair HX1000 or the beQuiet Dark Power Pro 1000W.
Anyone here who can recommend which one is better, or are they both very good PSUs? I just want something good, reliable and solid![]()
Maybe someone from OcUK would be able to help, as they deal with these PSUs all the time in builds 
I wouldn't call £150 a fortune for a good PSU...
