Fellow homelabbers, especially those of you with mini PC clusters…:

Do you run a UPS?

How does one go about sizing?

Thanks @madpilot @ivarch @DrRac27 @deb4sh @shertson

I have outgrown my existing APC Backup-UPS BX1600MI... This powers a NAS, a POE network switch and ten HP EliteDesk Minis...

The minis are all HP EliteDesk G2 Desktop Mini PC i5-6500, some have a 90W power supply, some 65W (spec: https://www.hp.com/sbso/hpinfo/newsroom/HPElitePC2015/AMSHPEliteDesk80035WG2DesktopMiniPCDatasheet.pdf)

How would I go about calculating the size of the UPS neeed?

ChatGPT is saying these devices would need a 2000 VA UPS with ≥1600 W output with options such as Eaton 9PX 2000 VA / 1800 W (9PX2000) or APC Easy UPS / Smart-UPS SRV 2000 VA / 1600 W... These are rather pricey!

Would a cheaper option be two more of the existing APC Back UPS 1600VA - BX1600MI..?

The battery on my existing APC unit is not supposed to be user replaceable (although they are youtube videos on how to)… Any recommendations on what might work instead?

Thanks!
