That's a crappy PSU and I'd just recommend replacing it with this one (depending on where you live you can get it cheaper after rebate, $25 on newegg).

But if you don't want to upgrade the PSU then I'd get the sapphire 7750 as long as it's a GDDR5 memory version, stay away from any 7750 with DDR3 memory.

If you are getting a new PSU then grab the 7770

If you'r worried about power but not upgrading the PSU get the 7750 as mentioned above

the 7770 also requires a 6 pin PCI power lead (i had one a little while ago, but got pissed off with crap drivers for it and went nvidia!) some GPUs that require PCI power will have a molex adapter so you can draw the feed from there, but i would agree with andrewcarr and get yourself a new PSU to go with. i'd say buy the nvidia card, just make sure you get it from somewhere that supports the Step-up program and you can upgrade it for the cost of the difference between cards if you play your cards right!

What is your budget? You might be able to build a much better computer that.
