Intro :

During the night or when going to work, and you decided to leave the PC on for some afk fishing for example. During this this, your pc drawing power. The power drawn from the PC leave while afk will be vary based on hardware and how you set up on the PC Power Management.

Basic:

While Balance/High Performance is best power management druing gaming where the game is hunger for "juice", when you going afk and leaving the PC the extra energy is a waste (unless your'e a Sultan). Picture below for example are power drawn when using AMD High Performance Power Plan :

Leaving this for let say 10 hours during the day going to work will accumulate quite high bill to pay at the end of the month. So basic thing to do when you going out/ going to work or leaving PC on overnight, change your Power Plan to Power Saver. What does Power Saver do? It limit the CPU usage to 20W, change the active core to minimal and shut down unnecasary power usage ( for example extra Hard Disk on your PC). Picture attached show Power Saver limiting the voltage (Intel CPU minimum voltage is different from AMD and so is previous generation)

And this is the power consumption :

That a 30W cut from 100W idle from Balance/High Performance Power Plan. You notice I put my screen into the Pearl Shop Tab, while you afk and put the screen on active game screen, Graphic Card still utilized. while it tiny amount of power, multiply it for few hours the effect does multiply too. Putting it on Pearl Shop Tab make it stay in idle state thus lowering power consumption.

Advance :

Basic step above should be enough for you to save some those high bills. Now what if you want to go further lowering the power consumption?

What you can do is change the Fan Management on BIOS setup. For example, I have 2 Chassis fan and 1 additional fan for CPU Water Colling Radiator. When the cpu is on Power Saver Mode, the temperature will drop to around 30+degree celcius. The extra power from the fan contribute the power draw. During this time, you can basically turn off the chassis fan and for my case, the extra 1 fan on my Water Cooling setup.

This is the example of the setup for the fan curve I customize on BIOS:

Chassis fan and secondary fan for Radiator. Set the Fan to DC mode and enable fan to stop.

As for AIO (Water Pump for Radiator) and another fan on the radiator, above is my setup. My fan power around 2.4W x 2 to 3.6W x 2, so as the fan powered down, it bring another 10W down with it.

From 100W~ going down to around 60W~ for about 10hrs is a quite big deal for me while staying competitive. This method will need you to sacrifice your RGB glory though, so you been warned.
