Power Issue HP Prodesk 400 G3 SFF

click here world, I am wondering if somebody has the brains to help me out!

I am having issues with my ProDesk 400. As soon as I plug it in the case fan and cpu fan spin for approx 1 second. The lights on the front also light up for 1 second. This is repeated over and over again. The fan spins, Stops, Spins, Stops and this goes on and on and on. I have tried to replace RAM, Checked processor paste in case of over heating this seems okay. Not sure what else I can try.. Has anybody ever come across this? It's as if the PC isn't even starting up. This happens as soon as I plug the IEC cable in. Without even pressing the power button this happens on repetition.

Any help would be hugely appreciated. THANK!!

Power Supply is probably on it's last legs

Thank you for this I will give this a check. I will try and source another supply to check. Multi meter is reading fine across rails but you never know.
