Is this PSU enough to power my system?

[OCS911]

Specs:
Abit IC7 Max3
Northwood P4 3.0Ghz at 3.75Ghz
ATI Radeon X800 Pro
Audigy 2 ZS Platium Pro
Plextor CDRW Preminum
WD 120GB 7200RPM 8MB Cache
Hitachi 250GB 7200RMP 8MB Cache

The PSU I'm looking for is OCZ PowerStream 520W, do you think it will handled all of that w/ stable rails or any alternative PSU?

 

[einstein2]

that will be enough. im running a 300W, and im guessing im going to need a new one, since upgrading my graphics card. I saw a 650W today around £50, but that for me is overkill. what would anyone recommend for my system?

 

[thegreek]

that PSU is perfect

Original Poster: That PSU shouldnt do too badly for that system.

einstein2: What brand PSU is that? A cheap 650W PSU usually means trouble. I have a 520W Hiper PSU (~£50 from Komplett.co.uk) and it has had no bother powering a dual XP system with 1GB RAM and two hard disks, and three optical drives etc.
