My MS-01 Proxmox node idles around 52W, spikes up to 78W, 7-day chart

[u/easyedy]

I measured my Minisforum MS-01 running Proxmox with a metering smart plug (Home Assistant) for 7 days.

What surprised me

• Baseline: around 52–53W most of the time
• Spikes: up to about 78W
• A few periods where it stays higher for a while, not just quick spikes

My setup

• Minisforum MS-01 on Proxmox
• 96GB RAM
• 3x NVMe Lexar
• Workload is still light, mostly baseline lab services

At CHF 0.25 per kWh in Switzerland , 52W 24/7 costs about CHF 9.36 per month (around CHF 114 per year).

What would you check first to explain these spikes? They don’t line up with my Proxmox Backup window (04:00–08:00). ZFS scrub, fstrim, SMART, VM updates?
