Hi I'm looking to upgrade my graphics card to a HD6850 or a HD7770 I was wondering if my XFX 450w core edition psu would handle the hd6850/hd7770.

My current setup is:
AMD Athlon ii x4 645 3.1ghz
4GB ddr3 2x2GB 1333mhz
300GB HDD
DVD Drive
ASUS M4A78LT-M LE motherboard(running onboard graphics atm)
450w xfx core edition psu http://www.ebay.co.uk/itm/360867933521?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649

I won't be overclocking the cpu/gpu at all and only thing else I'd probably add into the pc is another HDD later on.

Do you guys think I would need a new psu or would it be fine?

Thanks a lot :D
