I want to buy the Sapphire Radeon HD 5770 (Juniper XT). I have using a computer that is using a AMD Phenom II X4 945 Processor. Power supply I am using is a Rosewill RP500-2 500W ATX12V v2.01 Power Supply. I read this post http://www.guru3d.com/article/radeon-hd-5770-review-test/11 that says I need at "least 40 Amps available on the +12 volts rails" so I think I'm in the low end of the spectrum. Can I use this graphics card on my computer or do I need a new power supply (I prefer to not buy a new power supply if possible)

EEEh, it MIGHT work, though barely, it meets the power requirements-500 watts, but not the amperage, your PSU has two +12v rails, the first has 18 amps the second 16, which only gives you 34 amps. That PSU might work, but I wouldn't trust it, its a very low end PSU. Youd be better off with something like this

The power supply Patriot suggested is a single rail and has 40 amps which is should do well powering up the 5770.
