I need a temporary replacement for my system. Athlon x2 7550 dual core 2.5ghz and a EVGA GTX 460 Fermi. What is a cheap psu that will run this? Has to be from newegg for they are really close to where I live and can get parts next day. I have $160 and I am already buying a HDD $93 grand total, I need a psu for like $50-60 grand total.
