The 8300 is standard ATX.

This is the symptom that usually accompanies a failed power supply.
If you have access to another (PS) you could try as they are standard in the
8300, it would confirm this.

Just a quick update, the computer is actually an 8400. I tried two
other power supplies and they did no match up with the mother board.
The connectors on the other power supplies had 20 pins while the Dell
connector has 24 pins. I'm guessing it's proprietary to Dell. I'll
check Dell or ebay to see what I can find unless you guys have other
suggestions.

Be very careful when wildly replacing things. Some may appear to be
identical - only to create more damage later. Just another reason to
first take those two minutes to collect simple measurement rather than
'hope' a shotgun approach does not cause more damage. Some connectors
with same number of pins may put one voltage on the wrong pin. Color
and pin numbers for standard ATX supplies must match.

That simple measurement procedure would help confirm whether a new
supply is compatible as well as save time. How long did it take to
swap a power supply? Collecting numbers with a multimeter should take
about two minutes.

Pictures of standard connectors that may also help - to avoid more
damage:

The Dim8400 has a (24-pin) BTX power supply. These are now becoming
industry standard. The Dim8300 had a standard (20-pins) P1 connect.....
