it would be useful to have the CI server for Libre-SOC (as well as my other equipment such as router, switch, desktop, etc.) have a battery backup. luke suggested it: https://libre-soc.org/irclog/%23libre-soc.2023-08-10.log.html#t2023-08-10T00:14:36 after looking around a bit, I think I should get: $309: https://www.apc.com/us/en/product/BR1500G/apc-backups-pro-1500va-865w-tower-120v-10x-nema-515r-outlets-avr-lcd-user-replaceable-battery/ and $219: https://www.apc.com/us/en/product/BR24BPG/apc-backups-pro-external-battery-pack-for-1500va-backups-pro-models-formerly-backups-rs-1500/ which together last 40min at 500W my other choice that doesn't last as long when the power goes out and may not be supported as well on linux: $545: https://www.cyberpowersystems.com/product/ups/smart-app-sinewave/pr1500lcd/ there's EUR 400 left of bug #774, I'm fine with paying the rest myself since I'm getting a bigger than strictly necessary UPS since I want to use it with my desktop and other stuff too. (note to self: planning on also getting CORSAIR RM1000e at the same time)

I bought: $336.96: APC BR1500G Back-UPS Pro 1500 VA 10 outlets Uninterruptible Power Supply (UPS) $228.26: APC BR24BPG External Battery Pack for Back-UPS RS/XS 1500VA (plus the power supply and some other stuff which I'm paying for)

(In reply to Jacob Lifshay from comment #2) > I bought: > $336.96: > APC BR1500G Back-UPS Pro 1500 VA 10 outlets Uninterruptible Power Supply the UPS arrived and works (I didn't setup linux integration yet tho). I maxed out my desktop (with minetest and running openpower-isa.git pytest on 32 threads) and the build server (running 8 for loops in parallel in bash) at the same time, that comes to about 650W which is well within range. all the computers on but not doing much is about 300W, though if I turn off my desktop's monitors then it gets to about 180W (since I now have 3x 1080p 165Hz monitors). > (UPS) > $228.26: > APC BR24BPG External Battery Pack for Back-UPS RS/XS 1500VA didn't arrive yet, and UPS (the shipping company) says they never got the package yet...I'll wait a few more days and submit a claim to newegg. > > (plus the power supply and some other stuff which I'm paying for) the PSU arrived and works well!

(well, they go to sleep, which is what I meant and what the 180W is measuring)
