Keeping tradition with doing things backwards, I’ve finally got a UPS for the rack (mounted in the bottom of the stack). Got a PowerWalker VI 2200R. Its a 2U unit which is all the space I’ve got left in the rack. Decent price and decent I/O with USB, serial and a slot-in for network expansion + 4 IEC outputs. Its powering everything in the rack and connected via USB to my main server which runs a NUT server that other machines can connect to. A calibration run (100-80%) puts the runtime at about 20 min. Long enough that I’m comfortable setting things to shut down when 20% capacity remains. Summary, I sleep better now.

I was so confused about a package delivery. I opened the thread, saw Self Hosted, and suddenly everything clicked.
Cheers to nice cable management. Don’t look at the mess below my desk.
I prefer my power delivered by FedEx myself
Had to replace my UPS battery just a few days ago after a power outage reminded me that a replacement was well overdue. I share your feeling, now I can sleep knowing a power blip won’t knock out my servers and mess up my data.
Any suggestions for good UPS that doesnt break the bank? Maybe ill just mod my old ones and use car batteries.
+1 for UPS. So many PC gamers on reddit crying about their build getting fried by a power fluctuation. I never understood somebody that would drop 2-3k on a graphics card but not $300 on clean power delivery
Never heard of anything like that. Do you know anything where I can read up on it? Is it dependent on the country you live in and the stabliness of the powergrid? Because I do not even remember the last time I had no power, probably 5-10 years ago.
Same, over 25 years without issue. But I know once I get a UPS, Im going to have to babysit the thing and change the battery out in it ever few years. So it makes me wonder if its something I really need for just a gaming pc?
Depends on how much you spent on your PC, and how reliable your grid power is. Ours is decent, but we get windstorma that create variation in the transmission. 13 years ago I didn’t bother with UPS but then we had a power failure, back on, failure , back on, all within a second or so. Killed my Dell Powersupply and graphics card blew one hdmi port. Since then I have had one. had to change the battery last year for $80. It has saved me from brownout when a crow vapourized itself on the transformer outside our place. And every few months the logs show voktage correcrion for overvolting AC. it is cheap insurance that your syatem ia getting clean power. Last month my laptop charger power pack shorted internally, so UPS immediately shutdown power. Even if it wouldn’t have overloaded the laptop, it possibly prevented a fire since the short was not enough draw to blow the panel breaker
A great investment! Just a few nights ago my power died three times for a few seconds while my NAS was in a degraded state and resilvering. My UPS saved my ass.
Nice rack btw!
Great setup! I’ve heard that it is best practice to keep a little distance between servers/drives and the UPS just to be safe from vibrations or EMI. Does anyone know if this is still something to worry about?
What in your UPS is vibrating? You mean the fans?
Back when I built racks, our “standard” was UPS at the bottom, all drives at the top…but mainly for accessibility. Hadn’t even thought about vibrations or interference!
Drives at the top? Hell no. SANs are heavy, they go in the bottom half too (assuming a mixed rack). Especially if you have those disk shelves that slide out so they hold 3.5" drives three deep. Top of the rack is for network hardware and such.
