PSU quick question

hey /g/ got a quick question about a PSU !

http://www.overclockers.co.uk/showproduct.php?prodid=CA-048-CS

About to buy this, my system is, a 65w c2d, ATI 69502gb, 6gb DDR2 and two HDD's

Will this run? or will it not have enough power to work with the GPU?
current PSU is 550w THermaltake which cuts out when 3d use starts with a 6950, although it's years old now

i'm really a huge n00b with PSU's so any help would be great, Thanks !

Yes, it should work, but 700 watt PSU might be better for future upgrades.

650w will do aswell..
Gives room for OC'ing too.
