ASUS DirectCUII Radeon HD 7790 PSU Requirements?

Hello all,
I'm looking at the ASUS DirectCUII Radeon HD 7790 Card,
http://www.newegg.com/Product/Product.aspx?Item=N82E16814121772
but I'm just wondering how much of a power supply I will need. I have three hard drives, four including an external one, and a 100W processor. Should my 500W PSU suffice for everything?

  1. You should be totally fine with a 500w PSU (unless your PSU is a really crappy one). May I ask what PSU you have?

    I've got an APEVIA power supply...

    That's not a great PSU, but I think that it will be fine for the GPU you're getting.

    Well now that they've got ridiculous sales on everything, I'm thinking of getting the Sapphire Radeon HD 7850. Will it still work?
