Power supply

Hello Guys,

I currently have an Intel E8400 running on a gigabyte EP45C DS3R with 4 GB of DDR2-800 ram ,two harddisks , 7600GT and an Antec Earthwatts 500.

I plan to upgrade the graphics card to an MSI Hawk 5770 1GB card.

My question is whether the PSU is sufficient to run this graphics card in my system?

Thanks in advance..

  1. It should be, the HD 5770 is relatively efficient. The HD 5770 only consumed less than 400W of power in a Core i7 975 3.33GHz system. and the E8400 uses a lot less energy.
  2. No worries, it is enough
  3. It is more than enough. You can run a 5770 even with a good quality 400W PSU:)
    And you have a good quality 500W PSU!! ;)
  4. Yes, It's more than enough.
  5. The Antec Earthwatts 500 power supply is one of the psu's that is often recommended at this forum. You should not have any problems powering a system equipped with one ATI radeon HD 5770 video card.

    Here are the ATI recommended power supply requirements for the ATI Radeon HD 5770 and 5750 video cards:

    450 Watt or greater power supply with one 75 watt, 6-pin PCI Express® power connector recommended

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

    The recommendations are for an entire pc system..
  6. Thanks Guys ,

    So the MSI Hawk it is then..
