For a system using a single Radeon HD 6770 graphics card AMD specifies a minimum of a 450 Watt or greater power supply. The power supply should also have a combined +12 Volt continuous current rating of 25 Amps or greater and have at least one 6-pin PCI Express supplementary power connector.
Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Total Continuous Amperage Available on the +12V Rail(s) is the most important factor.
The BREEZE 500W (ARK500/8), with its combined +12 Volt continuous current rating of 14 Amps and with no PCI Express supplementary power connectors, is grossly insufficient to power your system configuration with a single Radeon HD 6770.
Yeah, I knew the Wattage wasnt a problem. The amperage I figured would destroy me.
Probably getting a rosewill Green series 630W ATX PSU. It has a single 12v rail with 50A on it.
Some guy on Newegg said you need 40A for the 6770. Just needed a second opinion.
