Hello Kukieli, and welcome to the forms.

A 400w PSU isn't enough information. What PSU model exactly? EVGA, Seasonic, Corsair? We need the model name too so we can diagnose the issue.

Example: Corsair CX450M, EVGA 400N1, Seasonic S12III 450w

I've honestly never heard of KMEX power supplies before. I tell many people to stay away from unknown PSU brands, as they are usually made with the cheapest materials and lack no protection what so ever. The fact that KMEX does not even have an 80 PLUS certification, tells me that it uses very cheap quality components.

Doing some further research, all KMEX PSU's don't even have PFC (Power Factor Correction). You can read more about that on this site -> https://www.sunpower-uk.com/glossary/what-is-power-factor-correction/

How long have you had this PSU, and what country do you live in? I ask this because many users on these forms are from around the world, and can't access some well known PSU brands.

That is a horrible PSU.

The fact that it's shutting down requiring you to unplug and replug the PSU points directly to a failed PSU.

Replace the PSU. This time with something decent.

Well considering it's a bad PSU and you had it for 7 years, it's time for something better.

If you have access to it, are you able to buy a Corsair CX gray labeled PSU? If you are tight on money, I highly recommend the gray labeled CX series from corsair. They are pretty decent and come with a 5 year warranty. For your setup, I would not bother getting anything higher than 450w. Unless you plan to upgrade your PC in the near future, with something much more powerful.

However, don't get the old CX green labeled ones, as those are plagued with problems.
