Hi guys, so I have this new Seasonic M2II Evo 520W, I followed the guidelines in the user manual as well as some tips from the internet but it simply won't work. I think it's dead, I connected all the cables I need into their proper place. Whenever I plug in the power and switch it on, there are no signs of power, there are no chassis fan spinning, there are no sounds and lights in the power supply, there is even no heat produced.

I already checked if the power cable is working, I used it to power a monitor, then on another computer, and it worked.

The first time I test to switch it on, it is only plugged on a charged UPS.

How can I assure that the PSU is dead? Is it really dead or just taking a nap, can you give me a list of things to check? BTW This is my first build and I'm really frustrated.
