I'd say a high quality 550W would be more than enough to power your system. Do you have a budget, and in what currency?

600W- 750W to be sure and possibly future proof.

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.
