Which CPU does it use?

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.
