Main application for this:
Intel 13900k/14900k, AMD 9950X3D/9970X3D, or HEDT CPU + Nvidia 5090 + large monitor or other power-hungry device.

e.g.: AMD Ryzen 9000 CPU with 16 Zen5 cores, 192MB of L3 cache and 200W TDP reportedly on the way https://videocardz.com/newz/amd-r...on-the-way
Intel also releasing a 52 core consumer CPU next year with 150w TDP that would benefit from this if using a 600w GPU.

The fact that this has sealed lead acid batteries disqualifies this product from consideration. Seems like a LiPo PowerStation would be a better value, have better performance, and longevity.

And what $300 1500w/1500va sine wave power station from a reliable brand would you recommend that can automatically shut down your PC when there is a power outage like this one can?

I'm giving up on these old lead acid UPS. The batteries never last. Next one I get will have some kind of lithium battery technology. As for shutting your PC down during outage, since the advent of NVME and SSD drives, boot time on PCs is very fast. So just shut it down when not using.

So the answer is none.

A dumb power bank is not comparable to this product. If you are away from the home and the PC is on when the power goes out, you are SOL with a dumb power bank. This one will run until the battery comes close to being low and then will shut down your PC, saving your drives from corruption.

And, unlike cheaper Smart UPS units, you can use the most power hungry CPUs, GPUs, and monitors with this unit. My PC would max out my old 900w Smart UPS all the time, once I upgraded to this it was smooth sailing (all the stuff i have plugged in peaks at 1200-1250w).
Plus on top of all of this its from a long time reliable UPS brand and you get a new battery with it.

I bought one. Just got the lower consumer version so I may return it for this at about $75 more. Thanks for sharing.

Sure I like the idea of LifePO4 battery in the UPS also, but I am also concern about the safety of such battery too. There is like one brand that pop up on Amazon on such UPS. And there are news from time to time about small Lithium battery blowing up such as a phone blowing up inside a car and stuff. Considering the size of the battery in the UPS vs phone, safety is much more major concern than a small chance of data lose or proven old tech like lead acid that require you to replace every 3-5 years.

The way I see it, if you're using these things for more than a couple mins at a time, then something's wrong with your strategy. I have my rigs all set to shutdown 1 min after power failure, and my NAS to shutdown after only 30 secs.

I think some people view these things as backup power supplies for continuing operations rather than "dont corrupt all my shit" emergency batteries to shut down from. Lead acid gets that job done just fine and 5 years is probably a lower-end estimate. They last prob 7-8. And then you can drop another 30 bucks on a new battery.

With the LifePO4, when it comes time to do the same thing, its gonna be pricey AF and good luck with standardized sizing.

I wasn't talking about how long the battery would last between Lithium vs Load acid. It's more about safety which we don't have a long record in UPS usage. The consideration for data corruption isn't necessary much about what type of battery it is, but rather what type or brand of UPS it is. That or vs no UPS at all. And to be more specific, the switchover time and communication between equipment and UPS. The only LifePO4 UPS that has been making a splash so far is Goldenmate. And from the review I have read so far, Goldenmate have a few issue compared to CyberPower and APC. One is that their switchover time is a bit longer, that may be enough for many but for some it's still not enough. Yes we are talking about under 10ms vs 10-20ms here. The other issue is that because Goldenmate is a new company here and it doesn't appear to have their communication working in a standard order here. Some people have report their comm w/ Synology NAS isn't working correctly. Meaning you cannot rely on having the NAS shutdown in a specific period of time after commercial power cut off.

I already have a couple UPS units. What is different about this one? I'm specifically looking to power my network equipment (router, switch, APs) so we can still have internet during outages. Would this do that or would an ecoflow or Jackery be a better option?

Important to note that it requires a L5-30R locking receptacle and can not be use in a regular outlet.

Where do you see that?
