I actually have no idea what brand PSU I have, it came with my premade cyberpower, which I bought when I knew nothing about computers and thought it was actually good. I upgraded my ram and GPU, but later I found my cpu and motherboard was lacking.
My motherboard is ASUS M2N SLI NVIDIA nForce 560 SLI Chipset, which I'm fairly certain can't CPUs without a am2+ socket.
I don't expect your PSU to have any problem since it's been running that OC'd video card and OC'd x2 5200+.
Just to be on the safe side I'd roll the GPU back to stock clocks for the initial install and testing period.
