My PSU won't turn on after I change something

Hi guys this is my first form post I just made a new build about a month ago everything's been working fine except my PSU it's an EVGA NEX 650G and whenever I change something on the computer the PSU just stops working at first I could fix it by unplugging all the cables and then plugging them back in but that doesn't work anymore so I guess I'm wondering if anyone's had the same problem or knows what I could do

 

have you check the fuse in the plug? 

What is a fuse plug?

 

what country are you in? 

US

 

 

igore my post then, you guys dont have fuses in your plugs over in the US of A 

Try jumpstarting your PSU using a paperclip to make sure it is the PSU that is fulty.
