  1. It's overkill!

    Here are the official power requirements for the brand new ATI Radeon HD 5850 and HD 5870 video cards.


    ATI Radeon™ HD5850 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 75W 6-pin PCI Express® power connectors recommended.

    600 Watt and four 6-pin connectors for ATI CrossFireX™ technology in dual mode


    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 75W 6-pin PCI Express® power connectors recommended

    600 Watt and four 6-pin connectors for ATI CrossFireX™ technology in • dual mode

    The power supply recommendations are for an entire pc system.

    Corsair, PC Power & Cooling, and Seasonic are some of the brands that have a reputation for high quality power supplies that consistently earn high marks in technical reviews. They are reliable, stable, and come with a 5 year warranty. Lately we've been seeing a few other brands offering some high quality units.
  2. A good 550 watt PSU will work for a single video card. Unfortunately, there aren't many PSU's smaller than 750 watts with 4 PCI-e power cables.

    And, yes. A 1 kw power supply is overkill.
