PSU won't work

Ok so I had a powercut (i get them every few weeks and theirs a switch in my garage that i turn back on and the power comes back) and my power supply blew up in this process, as soon as the powercut happened i went and turned the power back on, when i came back to my computer i could smell a sort of burning smell, and realized my power supply was fried.
So i got one of my older PSU's out which im 100% sure works, and I disconnected the broken and one and connected my older one, but the problem is that the PSU which is not connected won't work when I press the power button, I have neon lights inside my case and they turn on for a split second then off again. So its almost as if the power supply is working for a split second but doesn't seem to want to start my computer properly.

Help is very much appreciated.

your PSU might have taken out other components as it blew up.

I just tried unplugging everything about from the motherboard and it still didnt turn on for more than 1 second, not a good sign.

if you are 100% sure that your other PSU is working it's evident that the mobo fried, very likely in fact... :/

Generally speaking, that indicates that there is too big a load on the power supply. That usually means there's a short circuit somewhere. It may even be that the original PS is not burnt, it could be the motherboard.

This whole thing about having a power cut and you turning a switch back on, sounds kind of sketchy to me, btw. Sounds more like something in your place is overloading the circuits (not good). Some day there could be an even bigger burnt smell.
