A PSU for a DC Gaming Rig

[Blitz KriegeR]

I've been reading and researching for weeks now, and i'm ready to buy my Rig, but i know nuthing about PSUs. Can anyone help me out here?

Here is the Rig:
AMD 64 X2 4800+ Toledo Dual Core CPU (~165w load)
DFI LANPARTY SLI-DR Mobo
eVGA GeForce 7800GTX (~285w load)
OCZ EL PC4000 VX Gold [2x512] (~3.4v)
PLEXTOR PX-716SA/SW 8M Cache SATA DVD Burner
[RTPE: DVD-RW]
Maxtor MaXLine III 7L300S0 300GB 7200rpm /w 16mb Cache (SATA-150) HD
Western Digital Caviar 200GB 7200rpm /w 8mb Cache (IDE0133) HD

Right now, im wondering is a OCZ PowerStream 520W Power Supply enough?

Thanks for the complete lack of information.

Depends on the rest of your system. Generally you want at least 450W so you'll have an upgrade path for the future.

The OCZ PowerStream 520W is a great PSU for that rig.
