Try to update or reset sensors on "Hardware Status" tab in vCenter.
Or run the below command on your ESXi: services.sh restart
This seems to be a hardware problem. You may try the steps below.
1. Try to reseat the power supply one by one and then reset the counters.
2. You may try to file for a support ticket to your direct vendor to check for the problem.
