Bridge rectifier decided to turn into a fuse across mains. Neat. Thanks #CyberPower

Had a power outage tonight. The APC UPSes did fine. Most of the CyberPower UPSes decided to not do fine. No warnings. And when power came back, they all claimed to have a huge battery reserve (that didn't even last seconds in reality).
This is going to be an expensive lesson for myself, never trust #CyberPower

PowerPanel service for Windows (#Cyberpower UPS monitoring software) will crash when starting ... if there is an Android (perhaps specific model or perhaps other USB device) connected to computer at the time it is starting (probably a problem with enumerating USB ports). Reported years ago and it still isn't fixed. Engineers at Cyberpower can't even reproduce ti nor they care about it. 🤷♂️

also, snarl. My #CyberPower rackmount #UPS is beeping at me AND WON'T TELL ME WHY.

in 2016 I paid $94.95 USD on #Amazon for a #CyberPower CP1500AVRLCD #UPS, now the same unit costs $185, that's almost double the price! It's successor is $175. Has #inflation really increased that much?

@perry_mitchell Today, I ran a monitored test. I cut the power at 7:38 (visible through the drop in input voltage in white). For 12 minutes the UPS claimed to be at 100% (blue). Within 7 more minutes, it was down to 90%. After another 19 minutes it reached 50%. In total 50% battery charge, gave me 38 minutes.
Load was 80 W on average (about 12% of the UPS rating).
Monitoring ran on Unraid (nut-influxdb-exporter, #VictoriaMetrics, #Grafana) and was shut down by the server at 40% remaining battery level.
The #Cyberpower PR750ELCD contains two 7 Ah 12 V batteries in series. Your APC Easy UPS 1500 has two 17 Ah 12 V batteries in series, which should give you significantly more run time. Of course depending on your load. I haven't found exact specifications, but you should be able to replace the batteries with something like this (40€ per battery) https://hobbyhall.fi/fi/tietokoneet-ja-pelaaminen/tietokoneen-lisalaitteet/ups-laitteet/green-cell-agm09?id=2604838. https://www.youtube.com/watch?v=nZEG_-NgNqg Or go crazy and replace them with 60+ Ah car batteries https://www.youtube.com/watch?v=K_S55zITqxI .

A recent power failure (tripped fuse) convinced me to finally get a #UPS (Uninterruptible Power Supply). It can supply the home server, modem, router, switch and access point with power for about an hour. Protecting HDDs and services not correctly starting after a power outage were the main reasons. Uninterrupted internet access is a bonus.
I wanted something with a low self consumption and easy connectivity. I got a used #CyberPower PR750ELCD for 40€ and replaced the batteries with third party ones (Kung Long WP7-12(28W)-M/F2; I should have gotten the Kung Long WP1236W instead for a longer runtime). It has a self consumption of 6.1 W and uses USB-HID for communication. Luckily, I still had a USB B to A cable in my box.
It works flawlessly with NUT (https://networkupstools.org/). I use it through the NUT Plugin for #Unraid. I tested the CyberPower PowerPanel Business in a #Docker container, which worked (at least v4.4), but didn't give me any useful additional functionality.
When the power goes out and the UPS takes over, the home server keeps running until the batteries are at 50%. Then it cleanly shuts down to prevent any data loss. The internet connection is kept alive until the batteries are empty.
I don't expect issues with the electrical grid outside the house, but want to reduce my worries and work when something trips a fuse or the ground fault circuit interrupter cuts the power.
Sidenotes
- Why are there few reviews for things that are targeted at organizations? Does everyone do their own tests? (€ https://www.heise.de/select/ct/2022/6/2200610011263054853 was helpful.)
- A home battery doesn't help with a tripped fuse and I believe that, in houses, they are a waste of resources (better on a neighborhood level).
- Identifying the correct replacement battery was hard at first. Then I learned that nearly all of them are produced at the same two factories. Relevant fixed factors are voltage (12 V), physical size (95 mm height) and connectors (F2 aka 6.3 mm FASTON). Capacity (7, 7.2, 9 Ah) is flexible.
- Feel free to add your own USP stories or add useful information/corrections.
- I'd like to soon focus on other things again, thanks. -
Got myself a #CyberPower CP900EPFCLCD #UPS, one that doesn't use the battery unless necessary and thus prolonging its life significantly. Also pure sine wave. Looks like a very good purchase so far - except for its software service issue with Samsung phones. But hey, that can be fixed.

#CyberPower UPS monitoring service won't start if you have a Samsung Android phone connected to the computer through an USB port. #wtf

The National Cyber Force (#NCF), formed to help implement the National Cyber Strategy (#NCS) of #UK just released a report on how they aspire to be a #responsible #CyberPower

Decided it was time to get a #PCUpgrade and we're still in an age where the only realistic way to buy a GPU for a reasonable price is in a box that also contains the entire rest of a computer, so for the first time since my first self-built PC in the 90s, I started looking for a systems integrator to build me a new box. My main criterion was an AMD build for CPU and GPU. Nearly every integrator was only offering Nvidia GPUs, so I ended up going with #CyberPower.
What a goddamn comedy of errors. All seemed to be going well at first- I was asked if there was anything special they could do in the build and as I had plans to add more storage asked them to please prestage a SATA power and data cable to a 2.5" drive mounting point. "OK", I was told.
Fast-forward to yesterday, the PC arrives. Yay. Yay?
Not so yay.
As I'm removing it from the shipping box (which was gashed; thanks UPS), I hear a loose screw bouncing around inside the chassis. So I crack it open to remove the shipping foam and hunt down the errant screw, and find the following:
- Many loose connectors, including but not limited to the AIO pump
- The SATA connectors were not prestaged
- I paid a $20 line-item for "professional cable management" which apparently was code for "instead of a loose rats' nest of cables crammed into the drive cage, we will give you a very tightly zip-tied bundle of cables that are not routed though the conduit built into the case but just strapped to the motherboard tray and a rats' nest in the drive cage. This was mooted by the fact that I had to cut out all the ties to be able to reach the loose connectors that needed to be properly seated.
A couple hours later, woo, time to fire it up. No POST, or so I thought. Turns out it was only putting out video signal from the motherboard and not the GPU. Fine. But no BIOS setting I configured would give me a video signal from the GPU.
Okay, I'll deal with that after I get the OS set up. So I let it boot to the M2, and start the Windows OOBE, and... bluescreen.
Reboot. Blue screen.
Hm.
Reboot again, blue screen again. Check the BIOS- nothing super-hot, all temps look nominal; no overclocking is set up. As I'm staring at it, it spontaneously reboots again.
So I spend a couple hours pulling the PSU from my current, working, computer, and swap it into the new one in case it's a power issue, but no joy. Booting Linux from USB also throws a kernel panic within 90 seconds.
So I throw the original PSU back in, and just in case the seeming brick of a GPU is the problem, pull it out. No change.
If this is the state of buying a supposedly ready-to-use gaming PC these days, no wonder consoles and Steam Decks are so popular.
At least they replied to my support email in which I requested they either replace the machine or refund my order. Looks like I get to try another builder, presuming the refund actually comes through in a reasonable time.
Can anyone recommend another integrator I could look as I really would rather not spend the time building it myself this time around due to the "Getting A GPU While Not Being An OEM" tax that is still being levied.

This is the system pre-upgrade with the case sides and front removed. I’ve upgraded parts regularly since it was originally purchased on #BlackFriday of 2018 from #CyberPower PC. This includes the GPU, cooler, and case. #PCUpgrade #PCHardware

Anybody have recommendations for deskside #UPS units? My experience has been: #Cyberpower units will work fine for awhile, and then quitely estimate 10x the runtime they really have as their bats get old. #APC, OTOH, is like an inkjet printer: a week after the warranty expires, it decides the battery is shot and refuses to use it again, while waking you up 2x/night to beep at you for not getting a new bat.
Looking in the range of 1500VA.
