how much power does your system need? (lemmy.ml)

I wonder if my system is good or bad. My server needs 0.1kWh.

0.1kWh per hour? Day? Month?

What's in your system?

[–] GravitySpoiled@lemmy.ml 1 points 2 years ago (2 children)

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.

They said kilawatt hours per how, not kilawatts per hour.

kWh/h = kW

The h can be cancelled, resulting in kW. They're technically right, but kWh/h shouldn't ever be used haha.

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.

[–] tired_n_bored@lemmy.world 1 points 2 years ago (1 children)

Yeah but tbh it's understandable that OP got confused. I think he just means 100W

[–] kerrigan778@lemmy.world 3 points 2 years ago* (last edited 2 years ago)

He might, but he also might mean that he has a power meter that is displaying Kwh since last reset and he plugged it in and then checked it again later when it was all set up after an arbitrary time period and it was either showing the lowest non-zero value it was capable of displaying or was showing a number from several hours.

Which GPU? How many drives?

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