PC starts for a second and shuts down then PSU blows

[ovidiudascalu.timisoara]

Hello! Today, I started my PC and it started for a second then shut down. It did it multiple times. Earlier I heard a little pop when I plugged in the PSU cable, so I thinked it was the PSU (and 500W FSP) and I put my old PSU (180W Lenovo OEM) and it blew up with a bright spark. I have an I5 4460S, GTX1050. Thanks!

you installed a 180W psu in a pc that requires more power than that what did you expect XD.
remove that 180w psu.
the pop you are hearing from your older psu is the psu cutting off electricity to prevent damage that happens when there is a shortage for example, or other issues with the PSU.

follow the instructions in this video to check your 500W psu.
you can see if it's dead or not. if fans are spinning make sure you install it again correctly.

Thanks! I will try out this method and let you know. If the PSU passes the test what should be the problem?

Wait until you've tried new PSU before posting further questions.

The PSU works. Is it the motherboard that is faulty?
