Question 1000 va stabilizer and 850 w rmx850

[phoenixwing2022]

Hello, I would like to upgrade my PC and will need to replace my cx 550 w to rmx 850 w
I am currently use MAtsumoto Stabilizer of 1000 w, is it enough to support it ?

I connect these to my stabilizer

1. My PC currently use 550 W (based on PSU)
2. My Wifi TL-WR845N
3. Skyworth cable modem
4. Monitor Asus TUV vg279ql1a use 18 watt

My reason of replacing PSU is to accomodate my upgrade from i7 3770 and GTX 1660 super to i9 12900 k and RTX 3080 Ti

Thank you for any answer
