Comment on Servers go Brrrrrr
xthexder@l.sw0.com 1 day agoI’ve been measuring my server rack’s power usage, and it usually sits at around 500W with a 1U + 2U server (and GPU). My plan for the 1U has been to colocate it, but it’s an extra $25/month for each 100W increment, so I’ve been trying things like lowering the CPU power limit to save some money. Apparently turning my 200W EPYC CPU down to 150W barely makes a difference in my workloads, but that 50W is enough to save me quite a bit.

Man what are you paying per kwh? I’m averaging ~$0.21 AUD using a supplier who offers a variable market wholesale price.
I’d thought my rack was a bit of a hog with a z390 9900k and erying es system, but checking my current usage it’s vibing at 180kwh~
At 9:20 pm my rack has set me back $0.80 for the day (excluding misc connection fees and so forth). Most of my daily use would be in heating / cooling with two split systems & the wife WFH.

I’m in the PNW and pay about US$0.17/kWh at home, but for the data center rates, they charge based on peak usage because that’s how they size cooling and generator backups. Guaranteed redundant power and networking is just a lot more expensive than residential power.
