im relatively new to computer hardware and im wondering how i can calculate what power supply i will need?
the specs are as follows:

Intel Core i5-4430 Quad-Core Desktop Processor 3.0 GHz 6 MB Cache LGA 1150

MSI Computer Corp. Motherboard Micro ATX DDR3 1333 LGA 1150 Motherboards H87M-G43

Sapphire Radeon R9 280X 3GB GDDR5 DVI-I/DVI-D/HDMI/DP Dual-X OC Version

Corsair Vengeance 8GB (2x4GB) DDR3 1600 MHz

Western Digital Caviar Blue 500 GB SATA III 7200 RPM 16 MB Cache Bulk/OEM Desktop Hard Drive

Samsung Optical Drive SH-224DB/BEBE

please feel free to tell me if im missing anything essential to my first rig, this will be my first time building one

For a system using a single Radeon R9 280X graphics card AMD specifies a minimum of a 600 Watt or greater system power supply. The power supply should also have a maximum combined +12 Volt continuous current rating of 42 Amps or greater and have at least one 6-pin and one 8-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) rated at 45°C - 50°C ambient temperature, is the most critical factor.

Overclocking of the CPU and/or GPU(s) may require an additional increase to the maximum combined...

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.
