Welcome to Tom's Forums!

Hopefully, one of three things: 1. Short or 2. Bad PSU or 3. Poorly mounted CPU.

First and simplest, to test for a "short" unscrew ALL of the MOBO mounting screws and pull away from the I/O shield and dangle the MOBO and try to start {also you can pull-out the MOBO and breadboard}.

If none of these suggestions do it for you, a distant fourth possibility is a short in the HSF. I recently fixed a computer where the same problem you had was present. After doing the obvious tests on PSU, mobo, and ruling out shorts, I replaced the HSF and the computer started up w/o problems.

^ MOBO {manufacturer and wholesaler of cellular phone accessories?/urban music award show?} -> motherboard
