Closed What PSU for HD 5830? Tags: Power Supplies Corsair Components Last response: September 27, 2010 9:26 PM in Components Share Bibanu21 September 27, 2010 10:44:50 AM I was wondering if a Corsair HX520W could handle a HD5830 at peak load on a i5 760, 4 GB RAM, 3 SATA, mild OC on the CPU and GPU. I see that the Corsair is a 3 rail design at 18A per rail. Wondering if 2 rails would be enough to power the HD5830 (it uses 2 PCIe cables). Thanks!
