Question I just got a new 750w PSU, what capacity AVR should I get ?

[Rasty]

Currently I have a Koblenz RS-1410 700w AVR because I had a 450w PSU, but now I have a 750w PSU should I upgrade the AVR to an 800w-900w one ?

It would be a good idea. With AVR, you'd want it to be more capable than the hardware it supplies power to.

Of course, PSU's efficiency also plays a role here.
E.g 80+ Bronze PSU has efficiency rating of 80% (at 100% load), whereby PSU pulls from AVR 900W, while delivering 750W to PC.
80+ Gold PSU has efficiency rating of 87% (at 100% load), whereby PSU pulls from AVR 847,5W, while delivering 750W to PC.
80+ Titanium PSU has efficiency rating of 90% (at 100% load), whereby PSU pulls from AVR 825W, while delivering 750W to PC.

So what AVR capacity would you recommend me? currently my new psu is the XPG Corea Reactor 750w gold certified
I only plug my PC and monitor to the AVR (27" which according to the official site uses 22W)

Rather than buying standalone AVR, i'd buy true/pure sine wave UPS, with line-interactive topology, since it already has AVR in it. And besides the benefits of AVR, it also provides additional benefits when main power should go away. AVR doesn't protect against power loss.

UPS wise, 1300VA/780W would do fine for your build.
E.g CyberPower CP1300EPFCLCD,
specs: https://www.cyberpower.com/eu/en/product/sku/cp1300epfclcd

I have this very same UPS in use, times two. One is backing up my Skylake build, another my Haswell build (full specs with pics in my sig).

Currently a UPS is out of my budget:/
however I saw this on amazon

CyberPower CL2000VR 2000VA/1000W​

is CyberPower a good brand?? I also saw a koblenz one

Koblenz Bp-1400-i​

Yes, CyberPower is one of the best when it comes to UPS and the like. Even i have CyberPower UPSes in use. Other two good brands to look for are TrippLite and APC.

The one you linked is CyberPower AVR and would do fine for your setup, since it has plenty of wattage overhead.
