Power saver mode after an outrageous electricity bill

While I was not playing games recently, I decided to go full power saver mode with my home PC with the lowest possible configuration as humanly as possible.

After paying the latest electricity bill, I found myself swearing to the very foundations of stupidity that makes modern day Turkey as it is. While it is comforting to know people who vote for the wealth-hoarding selfish government suffer far worse fates than mine, I still pay an immense sum for a little electricity consumption. My bill went from 90 liras to 220 liras in two years. So called energy market is not well regulated in Turkey, natural gas is only supplied by one company and for electricity you can only pick the company which does the billing: Worst parts of so-called free market economy in motion.

Anyways, as I do not want to spend much more on electricity, I wanted to cut back on the bill. I removed all the unnecessary (read, entertainment oriented) equipment from the chassis. I removed my Vega64 GPU, replaced Ryzen 7 3800X with Athlon 3000G; removed my three slow spinning and dead silent 140mm fans from the front, reduced my Noctua NH-D15’s dual fans to a single fan, which only rotates while the CPU is over 50 degrees Celsius (which is generally not).

Noctua NH-D15 with single fan; not spinning much with an AMD Athlon 3000G.
System is actually running.

My power supply unit can report live consumption of system and net power drawn from the mains. So here is my ultra-efficient system in all its glory! Wall power tops 51 watts but it is generally around 30 watts while system consumes only around 18 watts. It is a pity that efficiency falls rapidly with the lowered consumption. It is important to remember that even my Corsair RM750i PSU is 80+ Gold certified one, efficiency certification tests are done at 50% or more load levels. With a load level around 5% we are far from 80-90% efficiency levels.

I agree that 61% efficiency is a shame, but no fans are spinning;
no bill is growing beyond imagination.

If you take a closer look on what HW Monitor reports, no fans are spinning during normal operation. Athlon 3000G hangs just below 40 degrees, needs to be over 50 for the single fan to begin spinning. Corsair RM750i’s fan will not spin until the load exceeds 40% (300 watts! it never spinned to be honest).
