Power Supply Help

[jays_rule]

Hi, I'm building my computer for the first time. I want to know if this power supply will do with my system. PSU: OCZ PowerStream 520 Watts. Would the 420 watts do?

Intel P4 530 3.0GHZ
Asus P5LD2 Deluxe
1Gb Dual Channel PC3200
Seagate Barracuda 120GB SATA
LG DVD Burner
Gigabyte 6600GT Turboforce

You can try http://www.extreme.outervision.com/index.jsp or http://www.jscustompcs.com/power_supply/

The first one is more detailed, but it takes the longest to load.

If you could be more specific, it would help more. (fans, how many sticks of ram to make the 1GB, PCI cards, # of USB ports, etc.-basically anything in the pc that would take power)
