iBUYPOWER Gamer Power 955 Core 2 Quad Q8200(2.33GHz) 4GB DDR2 500GB NVIDIA GeForce 9500 GT Windows Vista Home Premium 64-bit - Retail

Had ZERO problems with the 580 W ps? No problems after a month of owning, runs quiet and there is no need for a higher voltage

none really

This is average performance machine. It runs quiet

I will not recommend buying this type of machine because mine had a cheap power supply that broke down within two weeks. It is not worth to send the machine for replacement by paying delivery charge and wasting time just for that cheap power supply...
