How many drives do you have in your server? Or do you just have very high power costs? I thought drives consume ~7-9w unless they're very high RPM. Maybe consider upgrading to a few high density drives? Hard drive costs have corrected recently after the Chia craze last year.
My estimate is that it's idling at ~250w. I'm admittedly fudging the details a bit, right now archive-team-warrior is using a lot of CPU because it's archiving telegram, and that's pushing the number up.
Calculating it again the actual number is a bit lower than that, and it wasn't in US dollars.
