Unfortunately TrueNAS Scale does not support C-states, but it does down clock the CPU to 1.2GHz when idling.Zero spend and 14w saved, have a look at c-states and consider tweaking the BIOS power settings, fan profile (if not already tuned), disabling any unused controllers etc. and you should be able to improve on that by a few watts if you feel the need Realistically £12-13 odd a month isn’t huge for a server.
I have gone through the BIOS as per your suggestion, and disabled on-board LAN and HD Audio, but it has not yielded any noticeable power savings.
Fan wise I had 4 Noctua industrial 140mm intake fans running at 5V, which I have just discovered have unplugged themselves when I changed the power supply.
This is likely to be the source of my power savings not a super efficient PSU lol.
Update
Reconnected the 4 fans and idle usage just went up to 86W so the replacement PSU is apparently more efficient.
