hey man looks good i bought a xclio power supply a year ago running with a overclocked core 2 duo, 8800gts superclocked, 2 gigs ram and it works flawlessly for half the price of the psu ur getting.
Xclio is a branch of Antec's company so the quality is all there but your saving yourself a lot of money too!
