Is my PSU too weak?

I have an Antec BP500U. 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?

  1. should be enough, though it only has 1 pcie 6pin connector and the card needs 2. You'll need to use a molex to pcie converter cable, usually comes with the card as a accessory
