It is repairable, but not fun doing so - first locate a good, used PSU (from any source), then steel yourself for a good afternoon

Check the PRAM battery voltage or simply remove and boot. Try removing all the memory and re-inserting it. Then start up. Remove all memory and clean the memory card contacts with a clean eraser, very lightly. Then re-insert them and start up. Remove all but one DIMM and boot. Repeat with each
