How much power do I need to run a ASUS DirectCU II OC RAdron HD 7790

I just bought a Radeon HD 7790 and it turns out I don't have a 6 pin connector in my PC. I have a Dell Inspiron 531. The current psu is 300W. Will this run it or will I have to get a new psu. If so then can you reccomend me some budget psu's that is both compatible and can run my GPU.

  1. The HD 7790 is an 85W card maxed out. That's about 7.1A on the +12V rail: http://www.hwcompare.com/14285/radeon-hd-7790/
    So you don't need much more than the slot's power (75W) for the card. But yes, you do need to connect the 6-pin power header on the card. I would look at something like this: http://www.newegg.com/Product/Product.aspx?Item=N82E16817139027
    You don't want to go cheap on a PSU. Cheap ones tend not to last and usually take out something else when they go.
  2. I'd also recommend the Antec VP-450. I have 2 of them, and they run great:

    The one above is of higher quality, but this one is a good unit as well.
