Power Supply?

I'd consider getting a new power supply...probably 500W minimum.

I kind of like to think of it compared to minimum requirements for a video game. Sure, it'll work...but it might suck badly.

Try out newegg to look for good ones; it has tons of great reviews.

10-25 dollars
25-50 dollars

I ran through a little PSU wattage calculator, and everything, including the card, at 100% load would only use up 250W. That is of course, assuming the calculator is credible, which it seemed to be.

But taking your advice, and just to put my mind at ease, I found a 400W PSU for $20 which had all 5-star (egg? xd) reviews, so I think I'll get that one as well.

Thanks!
