im doing a new build with either a 7870 or a 7950 depending on how much i can get so i want the psu to be able to run the 7950. Would the xfx 550w be enough for my system? If not what should i get? i dont really want to spend more then £50-£55 ($75-$85) on the psi.

i will be getting either a 3470 or a 3570k depending on weather i want to overclock or not.
i will not be doing crossfire if i want to upgrade in the future i will just upgrade the card. Because im not doing crossfire is it worth getting an m-atx board?

thanks for any replies.

I agree, the XFX 550 is a good power supply.

If you don't need the extra PCIe slots, microATX will work just fine.

It is up to you. I shop for motherboards based on features and cost.

As said above you can save a few bucks if you get an H77 motherboards. If you aren't planning to overclock it should suit you just fine. H77 DOES support SRT. see the wiki page below for the main features of each chipset.

Yes. that PSU should be just fine. It is of the higher end 550W PSU. Really the only ones that would be better are a gold certified 550W from Seasonic or someone else.
