Afriad not. Your motherboard only supports 95W cpus. Any more and it wouldnt work. Even if you upgraded the PSU, it doesnt matter. Its about how much power the Motherboard can supply the CPU.
AFAIK the AMD Phenom II X4 945 is 95W. Any higher number pushes it into the 125W mark. Have a gander at the supported CPU list for the motherboard. It should give you a good idea on what to look for.
Unless anyone else can give better advice
