NEED HELP WITH POWER SUPPLY

There is no such thing as a Micro ATX form factor power supply. Several venders sell several differently sized power supplies under that label. The most common small power supply is the SFX, followed by the PS-III (looks like a full sized power supply from the back, shorter front to rear inside the case), then there's TFX and so forth.

If you could take a picture and post it somewhere of the exact power supply you have, I could make a recommendation.

FOR CRASHMAN...

Thanks for your reply to my question. About the picture you requested I can only send it to you via e mail or otherwise U can look at it right here

And I think U R right..my so called MICRO ATX after measurements is only smaller by fractions of inches..but even in that case, my DELL computer provides a special SLEVE where you slide the power supply IN to put it in the proper position and that SLEVE has no room for anything bigger.
Thanks.

CRASHMAN...this is the power supply I will like to purchase.

The critical dimension in this ATX PSU to fit in the aseembly sleeve of my computer is the width (the one that goes from the label side you see to the other side) and it seem's to be the same width. Only 39 dollars versus 99 dollars if I buy it from the previous site whose link I sent you before.

That's a full sized power supply. Most Dell Micro ATX cases did use the full-sized power supplies. As for the brand you're looking at:
1.) I don't see Fortron Source on the label
2.) The thing doesn't have an FSP model number
3.) I don't trust it to have anywhere near the quality of a real Forton Source (or the Sparkle Power version).

Some Dell's had part of the back blocked so you would need to make sure your power connector is in the same location (as in, top or bottom of the supply). You've already confirmed a full-sized supply fits in the sleeve, and the one you've chosen from Sparkle Power is a good unit.
