Hi!

I've got a AMD XP 2500+, 512 mb ram, Epox nforce 2, Radeon 9700 pro, audigy player, raid card with 2 slots, 1 cdr/rw rom, 1 dvd rom, 4 hd (ata 133) and 2 chassis fans. Powersupply of 300W

I clearly that i need to upgrade my powersupply, but the problem is how much would be enough?

thnx

Bigger is better.

Ditto, bigger is better. IMO I wouldn't go smaller than a 450w and preferable higher since you have a lot of components going. You should be able to find the wattage requirements for all your components, add them all up and then get a PS that is significantly bigger. It might cost a bit more but you will be happy you did. Spend the $$$$ for a good brand PS also, their components will be overspec'd and not prone to failure.
