That size UPS is simply unfit for any kind better gaming PC.
Successfull transfer to battery power also needs likely some reserve.
Active PFC draws some current almost continuously to keep current draw in phase with voltage and keeping bulk/primary capacitor fully charged.
So "transfer time" delay of UPSes lowers capacitor's charge state, likely resulting in momentary higher power draw to restore charge.

Though that would likely anyway trip the UPS and relays clicking during transfer from line operation to battery is easy to notice.
..:cry:

To add, the 3080/3090 can suddenly boost very high very quickly before ramping back down, I've seen a few reports of PSUs being blown up from it
 
Do you remember if those PSU's were of decent quality?

It was mostly PSUs that were right on the edge/under the required wattage for the entire system, Linus mentioned it in one of his small form factor build videos (basically saying it was why they use full size PSUs and not SFF PSUs in their builds)

As I understand it, those cards can turbo up very quickly and if the capacitors in the PSU aren't large enough to deal with the sudden increased power draw, they can fail.

Nvidia recommends a 750w PSU for the 3080, but personally I'd go with an 800w PSU since the difference in price is minimal and you have a little extra headroom

Ah thats a relief to hear, went for an 850w PSU(corsair rmx) and I was unsure if it'd be okay with the transient spikes the 3080 could have.
 
I got mine running yesterday but i have some things which I'm not sure of, every so often I'm noticing the screen brightness change very slightly, i can't tell if it depends on the content or not yet. Anyone know why it's doing this?

Other thing, i was using the DP cable that came with my other monitor. I changed it to the one included with this one and i had no signal at first, rebooted the computer and it started giving graphical glitches in long bars going across the screen while the bios loading was going on and it went blank before it got in windows, the screen went off and it wouldn't power back on again for roughly another minute. reinserted the cable again into both gpu and monitor and it hasn't done the graphical errors again yet.

It's still doing the brightness blink thing every so often when i open Edge on the default page with the news.

Is the screen faulty??

The display brightness changing is a power setting inside the options you can change I forget the name it's called.
