I have a 1500VA rated one, keeps my high performance rig running for about 8 minutes.
If you are worried, just run ONE Avr before the UPS. Never buy cheap UPS’s. CyberPower is cheap Chinese junk lasti checked. APC is made in America and a lot of businesses use them. Even Linus from LinusTechTips on YouTube got a massive APC backup installed for his servers..
APC UPS's your mainly paying for the name and the easy replacement batteries..........
I have had a Belkin 1200va with AVR UPS for about 8yrs now, running 24/7, have replaced the batteries about 3-4 times and has seen off about 3 pc builds in that time.. It's been a awesme UPS and never has let me down, so dont write off cheap UPS or not very well known UPS's as they can be as good or better then the big name ones
I upgraded the Belkin this time last year to a PowerWalker 2000va/1800Watts Online UPS, this is the spec sheet https://powerwalker.com/?page=produc...122099&lang=en
I paid £350.... Now if you wanted a APC UPS of this spec, it would cost you at least £1000 or not more. I have my whole main room plugged into it with a generator on standby,, so before the UPS runs out of battery power during a powercut (batts lasts about 2-3hrs), I get the UPS plugged into the generator and that sees me though a long extended powercut.
.........But remember a UPS is also a life saver during storms, with its AVR/surge protection constantly monitoring the incoming power. I have had times I have been away from home and there has been a storm, but I know that I can rest easy knowing the UPS is protecting my stuff.
I have taken a few photos of the inside as I had to change the fans for quieter one,, It looks dam impressive and so tidy too...........
