I think it has 2 12v rails at 18a each. I want to get a 4870 1gb to replace my current gpu. Will my present PSU be enough or do i need to get something more powerful?

You'll need to use a molex to pcie converter cable, usually comes with the card as a accessory Can't find your answer ? Ask ! Publish Related resources: ForumPSU Too Weak ForumIs my psu too weak ?
