Power Supply Question

This is what I have planned for my bro's system:

Athlon XP 2200 (or 2400 possibly)
512MB DDR RAM
80 GB 7200 RPM H/D
Creative Sound Blaster Live 5.1 PCI
Radeon 9600 Pro 128MB DDR Low Profile AGP 8X DVI/ CRT/TVO

Possibly a 17" monitor. And he wants a DVD-RW.

There will also be a scanner/printer combo hooked up to it, and a digital camera on occasion.

Is a 400w power supply good enough or should I go a little higher?

400w is plenty. If you have loads of drives, hd's etc. then go with a higher watt one.

Cool. I figured I'd play it on the safe side. I mean I only have a 900Mhz with 512, but have 2 hard drives (80/45), an internal 100MB Zip, a CD-RW and a 64MB card. My PSU is only 300w and it's been running without a problem for 2 years or so, and that's nearly 24/7.

He's only gonna have 1 h/d and possibly a DVD-RW. But with the larger CPU and all, i thought I'd bump it up a bit.

400W is plenty. Plenty.

Just make sure it's a good quality PSU, since a bad one will lead to oodles of problems.

Go with Enermax, Antec, PC Power and Cooling, Allied, Sparkle, and Vantec.
