I want to buy another ATI Radeon HD 5850 to install with the other video card of the same brand and model. The one that I have now is using two cables from the PSU already, I think its two 8 pin's. Thing is, I don't have anymore of those, so I need to get another PSU, I'm just not sure which one...any help?
Which is your CPU.? By how much have you overclocked it (if in case).? 679W should be enough power but i do not trust PSU's which output lesser than their advertised wattage.. Get a Corsair in there.. The TX 650W should do the trick..
