System Power Supply Requirements for a single AMD Reference Design Radeon R9 280X
• AMD specifies a minimum of a 600 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 40 Amps or greater. (Some non-reference design cards will require more)
• 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.

Toms E5620 pulled 220W at stock, 316W at 4.2ghz. Toms 280x pulled 260W. Not sure if you've overclocked at all, or if you're going to add a second graphics, but 48A (that load) would have those numbers just under 90% load for a 650W/54A, under 80% load for a 750W/62A. If you're going with a 2nd graphics card in the future, go with at least an 850W/70A.
