0.1kWh per hour? Day? Month?

What's in your system?

Computer with gpu and 50TB drives. I will measure the computer on its own in the enxt couple of days to see where the power consumption comes from

You are misunderstanding the confusion, Kwh is an absolute measurement of an amount of power, not a rate of power usage. It's like being asked how fast your car can go and answering it can go 500 miles. 500 miles per hour? Per day? Per tank? It doesn't make sense as an answer.

Does your computer use 100 watt hours per hour? Translating to an average of 100 watts power usage? Or 100 watt hours per day maybe meaning an average power use of about 4 watts? One of those is certainly more likely but both are possible depending on your application and load.

You're adding to the confusion.
kWh (as in kW*h) and not kW/h is for measurement of energy.
Watt is for measurement of power.

Lol thank you, I knew that I don't know why I wrote it that way, in my defense it was like 4 in the morning.

Which GPU? How many drives?

Put a kill-o-watt meter on it and see what it says for consumption.
