Surge Protector/UPS for my 1300W system?

[aeg567]

Hi all, I'm mining with 2x 3090s in my personal PC with a CyberPower CP1500PFCLCD PFC Sinewave UPS System, 1500VA/1000W. I have a 1600W corsair ax1600i power supply which is reporting Power In at near 1000W, sometimes barely above so I'm thinking this UPS/surge protector is already inadequate and now that I'm waiting to install a 3rd 3090 the power will be at least 1300W. Can I run 2 of these cyberpowers in parallel somehow? Or which single unit should I purchase?
