I have a Supermicro Redundant Power Supply with two units in it. I also have two UPS units, one for each of the Power Supplys. I was watching the LCD on the UPSs for the watt usage. The total watts equal about 400 Watts. This is where it gets strange. I observed the following, something that i have not seen on any of my 30 other Supermicro Redundant Power Supply setups.
It starts with...
UPS1 200 Watts UPS2 200 Watts.
Stays the same for 3 seconds and then changes with in a second to...
UPS1 0 Watts UPS2 400 Watts.
Stays the same for 3 seconds and then changes with in a second to...
UPS1 200 Watts UPS2 200 Watts.
Stays the same for 3 seconds and then changes with in a second to...
UPS1 400 Watts UPS2 0 Watts.
Stays the same for 3 seconds and then starts the cycle over again.
The wattage is sloshing back and forth 200 Watts at a time from one UPS to the other. I know it has been doing this for at least 6 hours now and i am not sure how if it was doing this before or not.
Does anyone have any ideas of what may be going on. Maybe some things i could try?

What type of behavior do you expect?
Compare your BIOS settings to the other servers and modify the configuration to match the existing systems in your environment.

All of the 30 other Supermicro Redundant Power Supply setups split the load evenly. I would expect this setup to have the load be UPS1 300 Watts and UPS2 300 Watts.

With the maturation of engineered obsolescence, even supposedly reliable equipment, such as enterprise-grade modular UPS systems, fails within a few years. Rather than a redundant PSU, try having two redundant servers, each with a regular PSU. Any component could fail, not just the power delivery.
As for the root cause of the phenomenon observed, I suspect the beat between the inverters with slightly different output frequencies.
