Psu needed

hey im building my pc

here are my specs:

core 2 duo e7400

nforce 630i mobo

xfx 9800gtx 512mb card

3gb ram ddr2

250gb hd

the question is that is this psu enough for my system even on load i.e(95% cpu usage) .

and also is this pc good enough for latest games like crysis,gta4,fallout3 etc.

This PSU is more than enough for what you are using. No need to worry. And yes, it will run latest games which u mentioned, but I would recommend at least a 680i motherboard for some future proofing
