I pulled this board from a Dell Dimension XPS P133c last week, and cleaned it up. Unfortunately I cannot get it to power on, so there is no way I can identify this board using a BIOS string. Plugging in Intel AA-649849-602 into Google does not yield any information either. Any information would be greatly appreciated!
Given the era and Dell, I can pretty much guarantee that the power connector is not a standard ATX power pin out. I think you would have to find the original Dell manual somewhere to find the pinout for sure, or maybe someone else here has a resource for that information.
The brown slot above the CPU socket could be a voltage regulator module, which would be required to power the CPU, although given that it's Socket 5 (which doesn't have split I/O and core voltages), it is probably more likely that it's a cache module, so may not be required to boot.

I was wondering if that may have been a proprietary power socket, although this is an Intel manufactured board. I mistakenly threw out the original PSU not thinking to check first. The brown slot you see is the COAST slot, and I have the giant cache card that goes with this board.

My guess would be it's a CoaSt slot. But will an unknown Dell there's no guaranteed way to tell 😜

It was pulled from a Dell Dimension XPS P133C. I have the cache stick with me.

I have some PSUs from PIII Dells that seem to fit your board. Not 100 percent sure, though.

Thank you. I might take you up on that. There is one other thing however, I realized I forgotton to mention: there's a 3.3v connector on this board as well. I don't know if that is what is preventing the board from powering on, or if it truly is proprietary.

I have seen that connector mostly on Intel/OEM boards with PCI slots, from Socket 3 up to Socket 5. This is what the manuals say about it:
PCI 3.3 VOLT CAPABILITIES To maintain strict compliance with the PCI specification, the baseboard provides a connector which can […]
PCI 3.3 VOLT CAPABILITIES
To maintain strict compliance with the PCI specification, the baseboard provides a connector which can be used to route
3.3 volt power to the PCI slots. The connector may be used with a separate 3.3 volt power supply or with a custom
designed voltage converter. Note: The on-board 3.3 volt regulator provides power for the CPU, PCIset and L2 cache
only, not the PCI slots.
I don't think it's necessary to use that connector, but who knows?
I have the same connector on my Dell Slot 1 board. Think I forgot to attach it once and the system didn't power up but may be wrong about that.
The Dell PSU's were good quality but you can get adaptors if you want to use a standard ATX power supply as well and will have the 3.3v connector as well, or the pinout is well documented now if you want to make your own

i have a dell socket 7 intel 430vx board with Coast module. It does indeed need a non standard atx psu with extra 6-pin connector for the board.
I have the original psu with it and it is this one: PS-5201-1D

Here are the connectors of my Dell PIII PSU. I suggest you purchase the ATX to DELL ATX converter if you haven't done so. Or, if you think my PSU would fit your motherboard and want a DELL PSU and are willing to cover the shipping cost, I am more than happy to send it to you. I am in Pittsburgh, PA.
It's the Intel Advanced/CM (Comanche) board. Apparently more than ten years ago someone pulled one from a Micron PC, although I couldn't find any info about it on the old Micron website. It's an odd board - AT style with ATX style power connectore.
