The latest CPC recommends the Be Quiet Purepower L8 530W. Similar price to those you're looking at and modular. Looks nice too. http://www.ebuyer.com/283835-be-quiet-pure-power-530w-modular-psu-bn181
Thanks for the replies guys, I've thought about it, and I think I might go with the CX600, because the XFX isn't in stock at CCL (checked their site, my other components are cheaper there). I was looking at the OCZ ModXStream series though... http://www.cclonline.com/product/18...-ModXStream-Pro-Modular-Power-Supply/PSU1077/ How does this do compared to the Corsair? They're both 80+, unsure on the amps/rails though. I was also wondering if there were any cheaper CPU alternatives? EDIT: Or there's the OCZ ZT series...http://www.cclonline.com/product/73.../OCZ-ZT-Series-550W-Power-Supply-UK-/PSU1259/
Going to buy what is essentially the build in the OP, but with a WD Caviar Black 1TB HDD, all from CCL tomorow.
