I was told my coolermaster 620w real power will power it aswell

Yeah, I'm using my power supply, case, harddrive and dvd drive from my current computer.

Thanks for the quick response

Ive pretty much decided to go for the xfx 5870 instead, Its only 50 pounds more, will my 620w still be alright to do the job?
