hi , tomorrow I will get this rig : Core 2 Quad Q9650 , Sapphire HD 6950 , Asus P5G41T-M LX3 , HDD Seadate 750 GB , 8 GB Ram 1333 Mhz , so what PSU should I use for this ?
For a system
using a single Radeon HD 6950
graphics card AMD specifies a minimum of a 500 Watt or greater system power supply. The power supply should also have a maximum combined +12 Volt continuous current rating of 32 Amps or greater
and have at least two 6-pin PCI Express supplementary power connectors
Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Total Combined Continuous Power/Current Available on the +12V Rail(s) rated at 45°C - 50°C ambient temperature, is the most important factor.
