Will this PSU work with my setup?

[Calibretto]

K well I got a PSU that I'm doing nothing with so I decided to replace my stock HP PSU. The HP PSU is running at 12V@12A which is crappy I know. But the one I got is 15A. Here's my setup:

P4 1.6GHz
768MB PC2700 RAM
40GB HDD
CD-RW Drive
no video card

I wanted to ask if the 15A PSU will handle it and will it handle a DVD-/+RW Drive?

Don't tell me to get a better PSU! I don't have an abundance of financial resources right now.

3A shouldn't make much difference. But it looks fine. What is the wattage?

It's a 400W PSU. The HP PSU is 200W.

Should be fine.
