Here is the official ATI power recommendation for a pc system with an HD 5870 video card:

ATI Radeon™ HD5870 System Requirements:

PCI Express® based PC is required with one X16 lane graphics slot available on the motherboard.

500 Watt or greater power supply with two, 75 watt, 6-pin, PCI Express® power connectors.

600 Watt or greater power supply with four, 75 watt, 6-pin, PCI Express® connectors for ATI CrossFireX™ technology in dual mode.

The power supply recommendations are for an entire pc system.

One video card, not an X2, a Corsair 550VX (41 amp 12 volt rail)

With that video card, I'd put in a Corsair 650TX (52 amp 12 volt rail)

But then, I tend to deliberately overspec PSU's.
