The "$400 Spirit of Mini-ITX" build earlier this year found that a system with a Pentium G860 and an overclocked HD7750 drew 113W from the wall. That system contained a 150W PSU.
If you can afford it, and it is available to you, get this: http://www.newegg.com/Product/Product.aspx?Item=N82E16814202002 (the one they used) although it is out of stock at Newegg right now. You might see if this one will fit: http://www.newegg.com/Product/Product.aspx?Item=N82E16814161418 noting that its cooler takes up more space, so check your case. If you cannot get one of those, here's a HD6670: http://www.newegg.com/Product/Product.aspx?Item=N82E16814102958 that will fit. Note that ALL of these cards use GDDR5 memory. Particularly in the case of the HD7750, DDR3 versions are slow abominations and rip-offs. Any of these cards should run on your PSU.

I had a Radeon HD 6570 with a 300W PSU, and AMD recommend 400W. So you might have to change your power supply.

AMD recommends a 400W PSU in the attempt to account for the liar-labeled junk (e.g. Diablotek, Logisys, Apevia, etc) that is not good for any more than half what's on their labels.
Dell OEM PSUs aren't junk; you'll have no problem with any of those cards.
