600W Power supply enough?

[iamkoza]

MY plan is to build this

-DFI LANPARTY UT nF4 Ultra-D Socket 939 NVIDIA nForce4 Ultra ATX AMD Motherboard
-AMD Athlon 64 4000+
-OCZ 2GB (2 x 1GB) 184-Pin DDR SDRAM Unbuffered DDR 400 (PC 3200) Dual Channel Platinum System Memory
-eVGA 256-P2-N527-AX Geforce 7800GTX 256MB 256-bit GDDR3 VIVO PCI Express x16 Video Card
-Western Digital Caviar SE WD2500JS 250GB 7200 RPM 8MB Cache SATA 3.0Gb/s Hard Drive
-SONY White 16X DVD+R 8X DVD+RW 4X DVD+R DL 16X DVD-R 6X DVD-RW 16X DVD-ROM 48X CD-R 24X CD-RW 48X CD-ROM 2M Cache IDE DVD Burner, Extra Black bezel included



I guess I don't understand how to calc the wattage I will need
I know the video card says 450 watts minimum....

I want to get the "OCZ PowerStream 600W"

Not sure if the 600W is enough

Should be plenty.

This is the best 600 watt PSU on the market.
