Was thinking of upgrading to an hd 4850, seeing as my current 7900 gt is struggling to keep up with today's games. Though I'm worried that my power supply isn't capable of handling one, it has 500 watts which is fine, but only has a combined total of 34 amps on the two 12 volt rails. Would this be capable of powering a 4850?

Current system:

Q6600

7900 gt

2GBs RAM

2 cd drives

1 floppy drive

1 HDD

X-Fi sound card

2 case fans (they are enough to keep the card cool)

It should be fine, the HD4850 doesn't use more than 12.5a, and I believe it's closer to 10a.

More than enough.
