Imagine not immediately disabling and removing Windows Update as soon as your PC boots for the first timeand pray your OS isnt going to want to process updates on the way down

VA ?? What ?? Watts ?
Volt*Amp which is equivalent to Watts + VoltAmpReactive. With modern and decent enough components connected to it they're aproximately the same (W = ~0.95 VA).
Take it as basically a more technical and correct way to describe the max power the ups can supply but also the way most likely to confuse or trick consumers.

consumer - what do I do when UPS runs out of power in 15 minutes
Eaton - switch over to your secondary UPS , then your tertiary UPS
It's just gymnastics with words to make the product look much better than it really is...Lol not even close, i did say it's to confuse and trick consumers after all

Because the standard power-draw of a common desktop computer on regular usage is at least 10x higher than a laptop (both currently and historically), requiring a different type of batteries to handle the load and thus making Li-ion or Li-Po batteries unfit. The batteries that do work are bigger and to be mass produced, have a physical structure that makes them fine to fit in a box beside your desk, not in a desktop computer.I wonder why is there no UPS and PSU single unit combination available for desktop computers.

Also, a laptop's configuration is set by the manufacturer and, being known and locked, so is the respective battery capacity, which you then get to complain if it's not enough to suit your needs but can't really do anything about unless return the product to then get another marginally better one.
In a desktop, configurations vary wildly and so it never really made sense to adopt a standard (because desktops have more of those than laptops) for that aspect. Finish the setup, measure the whole system power draw and get the corresponding VA vs. runtime vs. budget combination.

Aaaand you didn't read what I was replying to. Which is okay and very common in this forum.That's wrong, lithium batteries are perfectly fine for a Desktop ups and would make the units both last longer (both in terms of UPS function and durability/longevity) and be smaller and ligther. There are also several models in the market already with lithium batteries. Old school Lead based batteries are used because they are cheap and don't require much in terms of conditioning (lithium batteries need to be "exercised" from time to time for example, can't be kept static just trickle charging like lead acid ones). They are also the reason UPS can't keep the computer working for more than about 5 minutes.
Which is the whole point of a UPS: When power fails, you have 100% cap to drain. True for in-line, especially true for line-interactive.lithium batteries need to be "exercised" from time to time for example, can't be kept static just trickle charging like lead acid ones

VA ?? What ?? Watts ?
With these it's usually VA * 0.6, some are better but in general with 1500VA units they're only 60% efficient.Volt*Amp which is equivalent to Watts + VoltAmpReactive. With modern and decent enough components connected to it they're aproximately the same (W = ~0.95 VA).
Take it as basically a more technical and correct way to describe the max power the ups can supply but also the way most likely to confuse or trick consumers.
Basically this.Lol not even close, i did say it's to confuse and trick consumers after all

Standards. Sometimes they're great sometimes they stagnate everything.I wonder why is there no UPS and PSU single unit combination available for desktop computers.
It would be more efficient by avoiding the multiple AC to DC back to AC and on to DC conversions and instead offer something similar to a laptop power supply experience.

pF you're right I was thinking of 80+ for some reason.I was thinking of the other side, any modern PSU should have a power factor well above 0.9 (it's also a base requirement for 80 plus, at least 0.9 power factor at full power - lower power is less total power regardless so doesn't matter for this case), but forgot to account for the usual manufacturer shenanigans (they allow for a much higher reactive current, can't think of the advantage of doing so other than marketing since they still need to dimension their electronics for the full current, maybe it helps with dimensioning the battery capacity? that would still be just a marketing move imo though).
The 0.6/60% is not efficiency, it's power factor
Fun fact, any PSU has a hold up time after AC power loss (by design, not like it just happened to be there), it's just too small to do anything usefull.
Like others mentioned, standards, praticality, etc, don't really cater to an UPS built in outside of very specific industrial level applications.
If UPS manufacturers used watts by default, that'd be great. But yeah marketing believes "bigger number = better xd" so they go for VA and mislead some people, not everyone knows VA aren't equal to W in this case so they buy one thinking it'll support a 500 or 1000W load only to be disappointed when the power goes out.
