    PSU needed for ATI HD 4890

    What will be good capacity PSU to run ATI HD 4890?

    Will a Corsair 550 watt be enough to run this? Will it be adequate to run 2 HD 4890 in crossfire?

    ATI Radeon™ HD 4890 Graphics System Requirements
    1. PCI Express® based PC is required with one X16 lane graphics slot available on the motherboard
    2. 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)
    3. Certified power supplies are recommended. Refer to http://ati.amd.com/certifiedPSU for a list of Certified products
    4. Minimum 1GB of system memory
    5. Installation software requires CD-ROM drive
    6. DVD playback requires DVD drive
    7. Blu-ray™ playback requires Blu-ray drive
    8. For a complete ATI CrossFireX™ system, a second ATI Radeon™ HD 4890 graphics card, an ATI CrossFireX Ready motherboard and one ATI CrossFireX Bridge Interconnect cable per graphics card (included) are required


    So you can consider going for a Smps Corsair 750 Watts which will handle your needs more efficiently.

    its hard to just guide based on your graphics card.
    it can vary a lot depending on your other parts
