What capacity AVR should I select for my new 750w PSU?
It would be beneficial. With AVR, the device should offer greater capability than the power source provides.
Naturally, the PSU's efficiency also matters here.
For example, an 80+ Bronze PSU has an efficiency rating of 80% (at full load), meaning it draws 900W from AVR while supplying 750W to the PC.
An 80+ Gold PSU boasts a higher efficiency of 87% (at full load), drawing 847.5W from AVR and delivering 750W to the PC.
A 80+ Titanium PSU achieves a 90% efficiency rating (at full load), extracting 825W from AVR while providing 750W to the PC.
Instead of purchasing AVR modules separately, I'd opt for a genuine sine wave UPS with line-interactive design, as it already incorporates AVR functionality. Besides the advantages of AVR, it also offers extra protection when the main power fails. AVR alone doesn't safeguard against power outages.
For UPS options, a 1300VA/780W unit would suffice for your setup.
For example, the CyberPower CP1300EPFCLCD is suitable:

I currently use this model twice. One serves as a backup for my Skylake build, and the other supports my Haswell build (full specifications with images in my profile).
CyberPower stands out among the top choices for UPS and similar equipment. I also use CyberPower models in my setup. For other reliable options, consider TrippLite and APC. The AVR model you mentioned is suitable for your needs, offering ample power capacity.
