System Power Supply Requirements for a single Radeon R? ???
• AMD specifies a minimum of a 550 Watt or greater system power supply. (Minimum system power requirement based on a PC configured with an Intel Core i7 3.2GHz 130 Watt TDP processor.)
• the system power supply must also have a maximum combined +12 Volt continuous current rating of 38 Amps or greater
• the system power supply should also have at least one 75-Watt 6-pin and one 150-Watt 8-pin PCI Express supplementary power connectors. There are some non-reference design cards that require two 150-Watt 8-pin PCI Express supplementary power connectors (e.g...

There are some non-reference design cards that require two 150-Watt 8-pin PCI Express supplementary power connectors (e.g. ASUS Radeon HD 6970 DirectCU II, MSI Radeon HD 6970 Lightning).

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Sufficient Total Combined Continuous Power/Current Available on the +12V Rail(s) is the most critical factor.

Overclocking of the CPU and/or GPU(s) may require an additional increase to the maximum combined +12 Volt continuous current ratings, recommended above, to meet the increase in power required for the overclock. The additional amount required will depend on the magnitude of the overclock being attempted.

Antec Basiq Series 550 Plus (BP550 Plus)

• Ambient Temperature Maximum (i.e. without derating): 50°C
• Semi-Modular Output Cables: Yes
• Passes Official Intel Haswell Compliance Test: No although Antec claims Haswell Ready
• 80 PLUS Standard Efficiency Certification
