but will it work good with my PSU ? chieftec 450w.. my cpu is E7500. 10x!
If your Chieftec 450 Watt power supply unit has a combined +12 Volt continuous current rating of 24 Amps or greater it should be able to run your system with a single Radeon HD 6850 graphics card.
What is the Series and model number of your Chieftec 450 Watt power supply unit?
