I suggest this PSU: OCZ ModXStream Pro 700W Modular High Performance Power Supply compatible with Intel Sandybridge Core i3 i5 i7 and AMD Phenom. available also in Newegg and cheaper, that what I'm using. The CPU is okay but it cannot be overclock. Take a look at Micro Center website. The intel i5 2500K is cheaper and can be overclock. It's only $179.00. I am using it right now and I overclocked it at 4.7 GHZ.
