Two PCs stopped working after electricity cut off

[YonathanZ]

Hi,

 

In my brother’s store, electricity got cut off two or three times. Two PCs with identical hardware won’t turn on, but a third pc with different hardware survived. 

 

I’ve used the pin method to check the psu fan and it works. What else should I check and how?

 

Thanks

boot lights if the PC's have those. it would be very nice if you can say what brand or and model they are.

I don’t understand your question. You want the model of what?

The things you were talking about... The computers.

They are pre built by a local company. The psu is a Zeus PS520GW and the motherboard is a gigabyte GA-H110M-S2H. There’s no dedicated gpu.
