Im new to these forums, but I've been building computers for over 10years now, and I am going to list this directly from XFX's website to reinforce QI's suggestion.
XFX RECOMMENDED POWER SUPPLY REQUIREMENTS
* Non-SLI: Minimum 500W or greater
* SLI: Minimum 600W or greater
Now you need to add in that your using better than normal RAM, which will boost your power requirement up some more, and your raidmax PSU while being 500W is a low-end 500W PSU and the power its putting out across the 12v rails isnt sufficient to sustain your GPU properly. I suggest upgrading to a 700W-850W PSU.
In my system as you can see by my sig ive got
http://www.newegg.com/Product/Product.aspx?Item=N82E16817159085 which is a low-end 700w PSU, but the power distribution on the 12v rails is enough to power my 4870 across both PCI-E connectors.
When building a computer the PSU is one thing you never really want to skimp on your cost. In the Win98 ERA you could get by with a cheap PSU, but not so much anymore. If you are working on a budget, you should look into cheaper RAM. However if you do need to skimp on the PSU, make sure you have 200w-300w over the recommended level for your GPU.

Yours is simply a case of "it says it so it should take it."
Just because you have an AM2/AM2+ board doesnt mean you can slap any CPU into it. You placed a Phenom II X3 socket AM3 into an AM2/AM2+ only board.
Supported processors :AMD phenom, Athlon 64 X2, Athlon 64, Sempron ( AM2 and AM2+, hyperTransport 2600 MHz)
