by the way praeambulus do you have a micro atx chassis or a full atx? there would be a difference in psu size. from the looks of it, your mobo is a micro atx, but im not sure what you have it sitting inside of...

Edit: no it just looked like a micro atx from the pic. I checked the specs and it is an atx.

either way, just make sure you get the right form factor

First, I would remove the UPS from the system and test.

Then, try another power supply in your system or try your power supply in another system. Do you have access to another PS you could test with?

Another thing you can try is to disconnect all external devices, all drives, and any other power draws that you can and see if the system will boot with just basic components: PS, MB/CPU, RAM, Graphics.

If we can eliminate the power supply as the cause (prove that it is good) then we can move on to the other potential causes.
You knew what the problem was before it was cool
