■500W (or greater) power supply with one 75W 6-pin PCI Express power connector recommended
◦600W power supply (or greater) with two 75W 6-pin PCI Express power connectors recommended for AMD CrossFire™ technology in dual mode.
◦NOTE: Minimum recommended system power supply wattage is based on the specific graphics card and the typical power requirements of other system components. Your system may require more or less power. OEM and other pre-assembled PCs may have different power requirements.

A reliable 450W is more than enough.
If you wish to upgrade in the future, then a 550W would be useful.

Make sure to get a decent unit!
