I've found out that apcaccess is my friend. When used with attached UPC via USB, it tells a lot about the UPC:
https://linux.die.net/man/8/apcaccess and the line RETPCT : Battery charge % required after power off to restore power is the key. My UPC has a max power of 900 watt. RETPCT shows 30.0%. So: 900w x 0.30 = 270w 270 watt is the actual power draw of my server.
