or use servo motor type AVR with power rating greater than your PSU. It's the safest way because sometimes you would need to connect extra peripheral devices such as printers, scanners, and speaker systems to your AVR to protect them also.
Also be reminded that laser printers have high power rating so it is recommended if you use these type of printers, you might as well have a separate AVR dedicated to it only.
Servo Motor type AVR is better compared to I.C. controlled relay type ones because relay type AVR's produces surge current when switching from one voltage to another. Which could damage devices. But servo motor type AVR's are more expensive compared to their relay type counterparts.
