Start by carefully inspecting the capacitors on the motherboard. Capacitors are at great risk for failure. (It's possible like one of them is opening up). Make sure you don't have any stuck cooling fan. Check the 20/24 pins ATX main power supply connector. You may chase out all of the PSU wiring for short-circuits/bad connections. Many times when the smoke escapes it generally leaves a mark. Did you see the mark?
If all motherboard components/connectors/cables are OK so it’s probably a bad power supply unit... Replace with a new one.
