I'm looking for a PSU to use with my new board which will probably be a MSI P6N (NOT Platinum one), a Core 2 Duo processor and a PCI-E graphics card.

I like the Hiper 580 Type-R, Corsair HX 520, Antec TruePower Trio 550W and the Coolermaster eXtreme Power 650W.

Although the Coolermaster is the most expensive, at nearly £35 more than the cheapest of the others, it's the only one that actually has a review saying it's Core 2 Duo compatible.

EDIT: I have just found a OCZ GameXStream 700W for a bit less than the Coolermaster and one of the reviewers is using it with a C2D processor. However, it's out of stock and I want to build the PC this weekend so unless it comes back in tomorrow I probably won't be able to get this one.

Are the others compatible with C2D and my board? (The board has a 650i chipset if that helps)

Do some reading about PSUs. if you list your specs, I can calculate for you.

I went for the Corsair in the end as I've read very good reviews and it was the only good one in stock anyway. However, I'll post my specs so I know if I'm going to get any problems and alos for others who might read this in the future.
