It depends on the PSU! Not all 500watts are created equal. Total system power draw goes close to 400watts http://www.anandtech.com/show/7400/the-radeon-r9-280x-review-feat-asus-xfx/20 so the PSU has to have a strong +12 volt rail since that is where most of the power is used.

It says that it can consume up to 300w in the specifications of the card on the Asus web site. That would make a 500w power supply a very risky proposition. I would be more inclined to have a 600w or 650w PSU in my computer for that card. I realize that you have a computer with a 500w already in there but that's cutting it close. If you went ahead and got that card with the realization that it could need a larger PSU then you could go ahead and get it. But it's going to be up to you, me personally I would be getting a 650w PSU along with that card.
Okay, so I'm no absolute expert on GPU's but it seems as though the Gpu you want only draws about 400-450 watts on full load. Depending on the total power consumption of the rest of you PC, you could get away with it. BUT, I would make the card pull less power buy underclocking it, and or making it run cooler/quieter. Also, if you have an overclocked CPU, you may want to go down a bit on the speed. Just a suggestion, no idea if it will work.
