My current home server, a Raspberry Pi4 with 4GiB RAM is running out of memory and i wondered whether i could convert my existing desktop PC into a home server. The Pi4 with a SSD connected over USB consumes only 7.1W at idle and 9.9W at load. Before i replace the Pi with the desktop, i wanted to check if it could achieve low power consumption at idle.
Wolfgangs Channel on YouTube has some elaborate videos on reducing power consumption for home servers, including Google sheets with tests for several PSUs.
