Have you tried removing your PSU from the case and looking at the other side? Anyways it seems like you'd be fine with the three graphic cards that are on your choices, I'd look after the HD 6570.

MSI R5450-MD1GD3H/LP Radeon HD 5450 1GB 64-bit DDR3 PCI Express 2.1 x16 HDCP Ready Low Profile Video Card - Newegg.com

If your Power Supply handled your ATi X1300/X1500 without problems, It would run that card without problems (your old card pulls a bit more watt than the HD 5450).
