Not a chance.
Your Dells Micro ATX PSU is smaller.
The Cooler Master eXtreme Power Plus 500-Watt Power Supply measures 5.91" x 5.52" x 3.39".

This one will work for your computer.
This one will too and costs a bit less.
Whatever you plan to do with that Dell that makes you want a 550 watt PSU, it might not be up to the task.
 

Yes it will fit. The original power supply unit should be a standard ATX12V 2.x form factor.

But the real question is, "Why?" That's a crappy, overrated PSU. A 380W Antec Earthwatts would be a much better choice, and they're only $40 right now.
And no, you don't want Athena Power either. If you're limited to the smaller size, here's a unit by FSP that is efficient, stable, and has gotten good reviews at jonnyguru and hardwaresecrets: http://www.newegg.com/Product/Product.aspx?Item=N82E16817104075

Looking at the manual here: http://support.dell.com/support/edocs/systems/dim5150/en/om/WD846A02.pdf it looks like a standard ATX size, but the screw placement looks "off." I can't help but wonder if, as old as this one is, it may be one of the last systems Dell built that used proprietary connectors. If that's the case, you would need to contact Dell for a replacement (and likely pay through the nose).
