[Raymond Cockburn]

not sure what info you need but im buying a pc and then adding my own parts to it not sure is my power supply is big enough though here is the pc im buying http://www.currys.co.uk/gbuk/computing/desktop-pcs/gaming-pcs/pc-specialist-infinity-trion-barebones-gaming-pc-10114603-pdt.html

im adding my hd6770 and my 2tb hard drive

how much power would i need?

That PC has a 350W power supply and the HD 6670 draws around 90W. Another 25W or so for the hard drive. I think that's cutting it close, but it may work.

Edit: The AMD page states that the recommended power supply is a 450W.
