For a
system using a
single AMD Reference Design Radeon R9 270X graphics card AMD specifies a minimum of a 500 Watt or greater
system power supply. The power supply should also have
a maximum combined +12 Volt continuous current rating of 30 Amps or greater and have at least
two 6-pin PCI Express supplementary power connectors.
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.
