UPS APC intolerable noisy. Ups Apc Srv3ki Smart 3000v very noisy. Why they do not use 120mm fans! LINUS make a review UPS for a 1000W PC!

Not sure I follow the math... generally VA = W, give or take 10%.

Don't connect monitors or accessories to the UPS. It's job is to make sure the computer continues to run, not so that you can continue to use it seamlessly.

Are you really sure you need dual 3090s? If so, you're going to have to live with UPS in the enterprise spec (read: loud).

The problem is that if I go low I need to replace the battery more often.

No. You only need to replace it when it wears out, and if what you say is true (seconds per day), you'll be fine for a while.

In my house electricity can go out for a 1 second when switching to a better input line fase.

I purchase a  Ups Apc Srv3ki Smart 3000v.

I switch it on and is intolerable noisy!

Why they do not use 120mm or bigger fans? 

LINUS team make a review and hack it to reduce noise!

My pc is W1100, i5 9600k, 1080Ti and thinking in putting 2 3090 for game development.

You mean for changing the internal fans size ?

And the cpu for development needs to have more cores for graphids

ye but I need to cut I need to pay also software etc. My problems are GPU moving triangles and alpha blending. I do not use often so many cores. But if I go slow I can jump and purchase a used i9 cpu.

For game development dont use SLI

Why not? is so useful pushing my frame rate down. More FPS more staff I can add or manipulate in some applications.

Ho yes, that is so true. Is just a second. I need only the PC connected.

Time ago I purchase a UPS that spec was so close to my PC power that was not capable of online service and just few ms of power drop make my pc restart. So I decided to be more careful this time because I'm afraid of battery degradation. Did I exaggerate or can be close to specifications of running two 3090?

Put the UPS in another room and run an extension cord into your office.

I mean... as long as it's one with a heavy enough gauge. Like the kind you use in the garage.

The case of this is like a small PC. I presume there is 8 small batteries in it.

 

Putting the UPS in another room is an option but...

Yes, Instructions tells must be close to, in this case, the PC. No extensions. And If I put it elsewhere in the house small house I need to pass inside the wall special dedicated cables up to the Lab. 

 

The noise level is nonsense for a working environment and untolerable for a room.

I'm thinking in a car exhaust muffler does so well the job.

sorry but that is completely false, watts is power while volt amps is apparent power so you need the power factor as part of the equation. For a UPS, such as a 1500VA, you will see on listings it can do up to 900W. The VA rating is only the same as watts in a DC circuit and in that circuit it does not change. Also you cant say 'its almost always this give or take some' for a set mathematical calculation, it doesn't just change as you please.

I was basing my number off observations from my own UPS (currently 192W/200VA, for the record, with two desktop systems on it) and what I remember from when I took power systems in college. Most decent PC power supplies are supposed to be >0.90 pf (at full load, per 80 Plus standard), so my ±10% is reasonable. I was mostly questioning OP's W number at half the VA rating.

 

Ballpark figures and napkin math come up all the time in engineering, I don't know where you're getting that they don't. Error bounds on a given value are almost universally present (especially in EE). This is engineering, not hard math. There's no physical system that will operate exactly as your mathematical model predicts, hence error-bounds.

 

If at which point OP was actually drawing 2.4KW/3KVA from it, then we can have a discussion about power factor and real/reactive power, but as it stands, OP is still nowhere near that.
