I just bought an Antec 350 Watt power supply for about $65, and I'm now about to upgrade my computer a bunch and am wondering if 350 watts will be enough for the following setup:

AMD Athlon XP 2500+ Barton
(2) Corsair 256 Mb XMS PC-3200 DDR RAM
Asus A7N8X-X Motherboard
GeForce4 Ti 4600
40 Gb hard drive
CD-ROM and CD-RW Drives
5 case fans (2 front, 2 rear, 1 middle)
Logitech Z-340 speakers, a printer, and maybe a scanner (if those matter at all)

Any help is appreciated, thanks! :D
