You need a 500w psu with two 6 pin pcie connectors.
$50 will not usually buy you a good psu.
Look for a tier 1 or 2 unit from this list:

Start with Seasonic, XFX, and Antec.

I have no problem overprovisioning a PSU a bit. Say 20%.
It will run cooler, quieter, and more efficiently in the middle third of it's range.
A PSU will only use the wattage demanded of it, regardless of it's max capability.

A little higher than you wanted to spend, but not that much higher, and is an excellent PSU.

The first two tiers on that list are the best units for any spec. Those are the ones you want to get, you don't want to skimp on a PSU. Lower quality units tend to not deliver everything that's listed on the box and your mileage may vary, sometimes they last forever, sometimes they last a month, the thing is, with low quality PSUs, the chance that it will take out all your other components with it when it goes is much higher.

The PSU I linked is a nice one. After the 20 dollar rebate, it's actually a pretty good deal.
