UPS suggestions for 1000w?

Specs

9800x3d

850w psu
64gb ddr 5 6000mhz ram

My current apc ups as well as a Smartplug show max draw of 630 Watts with cpu 50 percent and gpu 100 percent.

Gpu draws 470 to 500, cpu upto 70 to 80 or so and the other parts make up the rest.

I have just installed a luminous 3.5kva inverter for my entire house. It has ability to be put in ups mode.

I think you should power limit your GPU, 500W for a 7900XTX seems high. I'm safe to assume it's an AIB board with auto OC feature which is why its consuming over the reference card's 355W limit. 410-430W should be good without affecting performance. Anyway It seems like your PC does take approx 600W if we include other components + PSU efficiency loss.

This is the one I have and it says switchover is <10ms and the manual says 'pure sinewave inverter'. This is what my PSU it says about hold up time:

That inverter is a beefy boy. You should have no problem with this one. In fact you can most probably remove the UPS and just use this inverter in UPS mode. May I know which model that 850W PSU in your PC is? I will try to find it's hold up time, maybe there is a cybenetics report on it which will have it accurately listed. But looking at the things right now it looks good.

Could you please tell the exact model of this luminous inverter, and what is it's waveform type and how much is its switchover time?

This would be very good option, if we could make sure that the PC would not shutdown during the switchover time.

As someone has already mentioned, even if the inverter is labeled as pure sinewave, still the PC might shutdown, which could cause data loss and other issues.

Buying a PSU with bigger capacity might be helpful in this scenario for sure. I am not sure if this has any minus points, other then higher initial buying cost of bigger PSU.

Bro went ahead and asked the AI to make a spam post /s

Requirement: ≤ 10 milliseconds (ms).

• PCs require a transfer time of <12 ms to avoid shutdowns. For optimal performance, aim for inverters with ≤5 ms switchover time in UPS mode212.
• Example: If the inverter’s transfer time is 8–10 ms (common in UPS mode), your PC’s power supply unit (PSU) must have a hold-up time ≥17 ms to bridge the gap28.

This is a weird answer to me. Numbers don't add up correctly. Hold up time is the duration a power supply can stay in power OK condition which is to say that it's able to operate in its specified standards. As soon as it can't it will cut off and PC won't get any more power. Change over time means how fast the inverter takes over the job of delivering stable supply of power. If I'm to assume both should be equal or be within their range then why is the AI saying inverter must have 8-10ms when holdup time should be equal to greater than 17. There's a 7-9ms of gap there. Also ATX 3.0 and below are required to have 16-17ms of hold up time but not ATX 3.1 so I guess AI knows this and that's why mentioned specific hold up time instead of just saying all PSU have.
