Power-Meter is an OpenHardwareMonitor client that calculates approximate electricity cost and consumption. This program is not for exact calculation. If you need exact consumption metrics, consider buying a kill-a-watt device.
Firstly, install openhardwaremonitor and make sure remote web server on port 8085 enabled. If you change the port, do not forget to change in global variables too. OpenHardwareMonitor should be running background.
You need to set your device sensor paths and other variables for proper calculation. You can split children with underscore. This means that Cpu Package under Power under AMD Ryzen 7 3700X on OpenHardwareMonitor GUI.
You can add positive or negative offset watt for ram, motherboard and other peripherals that don't too much fluctuate power consumption according to your usage.
- Around 3 W of power for every 8 GB of DDR3 or DDR4 memory can be allocated.
- Around 30 W for regular motherboard, 65 W for high-end motherboard can be allocated.
- According to these; I've 32 GB DDR4 ram with high-end motherboard; so I've set (3 W * 4) for ram and 65 W for motherboard.
