How much electricity does an average PC use per year?
A typical desktop PC consumes between 80W and 400W depending on usage. Over a year of daily use, that equals roughly 200 to 1000 kWh, which costs between €30 and €180 in electricity in Europe.

r/Windows10 on Reddit: Monitor pc power consumption
November 12, 2023 -
Is there a way to take in account how much watts my pc consumes in a month and store them in a log file or a excell that i can look into? I am on windows 10/11, i know a software called hw monitor that displays a rough amount of instant power consumption but i don't know if i can store it in files automatically. Would be quite useful as i have 5 pc running 24/7 and i wanted to start taking in account how much electricity they consume, even if it is a rough estimate, without using external wattmeters.

The only way I know is to buy a device called Kill A Watt and plug it in between a machine and the wall. It will tell you exactly what the device pulls in a set period of time.

there isn't. you can check cpu power and gpu power, but that isn't the whole system power or even the whole graphics card power for example. to get the most accurate easy to get system power, so the total power from all the applications you are running, you need a power meter. a power meter will tell you the power , that you pull from the wall, BUT that is NOT the power, that the system is consumer, but rather the power, that the powersupply is using. you then need to multiply that number with efficiency of powersupply at the load and THEN you get the best estimate of your powerconsumption. example to follow: 750 watt psu, computer running prime 95 + furmark = 500 watt from the wall. psu has 92% efficiency at 400-600 watts. so 500 *0.92 = 460 watts. so 460 watt usage of the system and 500 watt from the wall (psu wattage used) the powermeter i got was i think like 20 euros and is good enough.

r/buildapc on Reddit: Safe way to monitor gaming pc power consumption
January 18, 2022 -
Does anyone know of a safe way to monitor the power consumption of my gaming PC and display it in display software like https://grafana.com/. I am aware of software solutions like Open Hardware Monitor these have their downsides. I was planning to use a tp-link p110 smart plug to do this, but a friend of mine said that this is one way to get your house burned down when using a high voltage PSU (i.e. corsair 750w 2019). 🔥😅 I am also aware of the corsair ICLUE 4 software, but the performance PSUs seem to be incompatible with this software. Does anybody know a safe way to get the real-time or weekly power consumption of a gaming PC? Maybe a kill-a-watt switch is better suited?

You're fine with P110, it's rated for 2990W/13A, which is well beyond consumption of 750W gold PSU. Gold would be 87% efficiency at 100% load, so 750/0.87 = 863W drawn from the wall, or less than 1/3rd of P110's rating.
