I'm planning on a build soon, but I was wondering if a CX500 alone can manage to power all of this without shortening its life. Here are my specs:
AMD Phenom X4 960T at 3.0 GHz, planning on unlocking to 6 cores
Sapphire Radeon HD 6850
Corsair Builder Series CX500 500W PSU
G.Skill 4GB RAM @ 1333 MHz
Western Digital 750GB HDD @ 7200 RPM
Rosewill Challenger ATX Mid Tower Case
and a 1600 x 900 monitor
If someone could also make sure all of these components are compatible with each other and fit in my case (especially the video card), that would be great. If the HD 6850 requires too much power, would an HD 6790 suffice?
For a system using a single Radeon HD 6850 graphics card AMD specifies a minimum of a 500 Watt or greater power supply. The power supply should also have a combined +12 Volt continuous current rating of 24 Amps or greater and have at least one 6-pin PCI Express supplementary power connector.
The Corsair Builder Series CX500 V2 (CMPSU-500CXV2), with its +12 Volt continuous current rating of 34 Amps and two (6+2)-pin PCI Express supplementary power connectors is more than enough to power your system with a single Radeon HD 6850.
