ok ok , i've decided for the 520W version of the Corsair HX620 (Corsair HX520) i just don't want to have to buy another PSU in the not to soon future.
i did the calculator thing on a website and according to the things i want it did suggest 520.
Thankyou fo r your commetns and more suggestiosn are welcome the tfull listing of things i want is here:
AMD Athlon™ 64 X2 5200+, 2.6 GHz
ASUS M2N32-SLI Deluxe
e-GeForce 8800GTS 320MB Superclocked x1 (upgrade to SLI later))
Corsair Memory XMS2 1 GB PC2-6400 DDR2 RAM x2 (upgrade possibly)
Western Digital (WD5000AAKS) 500 GB SATA Hard Drive x1 (will add another later)
DVD / CD optical drive (mabe two optical drives)
sound card
so is 520W still over kill, as from what you gusy say 600W is,...
thanx again
