Check Ventilation, Cooling, the Antminer is probably overheating and to prevent more damage to the system.

the temps are always 45-55 c

Most certainly it's a PSU problem, try swapping with a diff one.

It looks like a damaged PSU. I recommend a good CM(Cooler Master)V1000 up to 1000 watt and I am sure you will not have any more problems if the temps are like you are saying.

However I am curious, where do you live because S5 is profitable only with free electricity ?

Since you have 4 antminers, I presume you have more than 1 PSU?

Give another PSU a shot, if it's just cutting out and you're not able to power it back on, I'd say PSU is at fault.

Worth a try?
