Power Supply Suggestions?

For a system with a single Radeon HD 6870 graphics card a 500 Watt or greater power supply with a minimum combined +12V current rating of 30 Amps is recommended. The power supply unit must also have at least two 75W 6-pin PCI Express supplementary power connectors.

For a system with two Radeon HD 6870 graphics cards in 2-way CrossFireX a 600 Watt or greater power supply with a minimum combined +12V current rating of 42 Amps is recommended. The power supply unit should also have at least four 6-pin PCI Express supplementary power connectors.

The two power supplies recommended by Silvune are able to handle a system with two Radeon HD 6870 graphics cards in 2-way CrossFireX. Both units have Seasonic as the OEM so they're top notch in quality.
