Used to use Tripp-Lite. A better alternative, I think is this: ZeroSurge based in New Jersey. Look at their website. They got their start building boxes for the military down in Florida. I have never, ever had an issue with ZeroSurge boxes.
it is not possible for not using extension cord / socket for a mining rig…
as you need 2 x PSU at least…
Hopefully it is because of the poor extension socket.
I have changed to a schneider extension cable with 4 sockets.
hope problem solved… fingercrossed
