I worked good out a whole ago, so here’s a copy and paste:
I have a power monitoring plug on this setup, so I can tell you exactly how much!
CPU: 2 x Intel® Xeon® CPU E5-2680 v4 @ 2.40GHz
RAM: 512 GiB DDR4 Multi-bit ECC
My disk layout is like so:
This draws a fairly consistent 650W, including a POE router (15.6kwh per day). My current electricity price is 39.38c/kwh… HOWEVER I have a cheap rate of 8c/kwh between midnight and 6:00am, and free power between 11:00am and 2:00pm. I also have solar which tends to cover ~10:00am to ~2:00pm, but its dependant on sunlight so I’ll ignore it for now.
So:
12:00am-06:00am = ($0.0800/kwh * 0.65kw) * 06 = $0.312
06:00am-11:00am = ($0.3938/kwh * 0.65kw) * 05 = $1.279
11:00am-02:00pm = ($0.0000/kwh * 0.65kw) * 03 = $0.000
02:00pm-12:00am = ($0.3938/kwh * 0.65kw) * 10 = $2.559
Total = $4.15AUD per 24 hours, or $1,514.75AUD per year
My Merross plug is showing that I’m currently averaging a daily consumpion of 15.021kwh, and I’m not accounting for the hours of solar offset so the actual dollar value will be a little lower. But still. Fair few bucks.
