Need a PSU for my MSI N9400GT. Help A n00b out.

Hello peeps. I just bought this card since it's cheap (37 bucks after mail in rebates). I'd like you guys to recommend a decent PSU (preferably under $50) that will keep up with my card.

Right now I have a Gateway GT5670 (crappy,I know) with 2 hard drives connected to it (Master: 350GB and Slave:1.5TB) 4 GB Ram, and the rest came with the computer.

Yes I know my PC is not the best, nor is the card I just purchased, nor will it keep up with the latest games, but in all honesty I don't plan on playing too much on my computer. If I can play Oblivion at high settings then I'm a happy camper.

Thanks in advance.
