Four Solarpanels are already in place to reduce our overall power consumption. Changing the hardware would also mean less computing power. I also use the server to recode stuff to x265.
Nevertheless, i just bought a used LC-Power LC6460GP4 for 16€ (plus shipping). 460W, 80+ Gold Rating. I think i will give that a try, maybe it is at least as efficient as the SuperFlower so i have a good replacement plus it is semi modular.
Thanks for the hint, already knew that list. I bought the MWE 400 following that list, which is also not as efficient as the Super-Flower.
Like i said, tried the PicoPSU just yesterday with a rumored fairly efficient powerbrick an the PC needed 1-3W more than with the Superflower.
I dont have a specific goal how low i want to come. My Server is an i3-10100 with five HDD an one NVMe. I know that the 20-25W on idle (with disks spun down) are good. But i have also read that there are people which manage to run similiar setups at 15W using really pricey platinum PSU’s. But i am really surprised that i didnt find any PSU which is more efficient than my 14 year old and dont cost a whole lot of money. Nevertheless the PSU is 14 years old so it would be nice to have a goold replacement at hand, in case it dies.
1W of 24/7 saved power equals approx. 2.5€. I dont have my PV System in my calculations, but it really does not matter that much. Fact is that i will need a new PSU. Maybe in 3 months or in 3 years, and for that is search for one which is highly efficient and on a budget. I know that it makes no sense buying a 100€ Platinum PSU to save 2€ per year.
