What Happens When You Plug A PSU Into A Wall Without Any Other Components and Turn It On?

Hi,

 

I was just wondering what would happen if I did what the title says. The reason for this is I want to test my power supply. My PSU has an rgb fan, so that would be my way of telling if it is working or not. I do not no much about electricity or how every component works, so this question my sound stupid.

 

-Thanks

Depending on the PSU, nothing, or it simply turns on. Some PSUs only agree to turn on if they detect a load connected to the 24-pin connector, others are happy to turn on without.

Hand, n. A singular instrument worn at the end of the human arm and commonly thrust into somebody’s pocket.

All ATX power supplies will turn on when these pins are shorted:

Nope. I have two that won't turn on unless there's a load, even if you did short those pins.

Maybe the design differs a bit from the ATX standard.
