Is it worth to paid 70-80 GBP more for UPS with pure sine wave like CyberPower CP1300EPFCLCD ?
It is more efficient and does help with compatibility of power supplies as there can be some that will reject a poorly situated sinewave thinking it’s rejecting bad power by shutting itself off. Being a stepped simulated unit I personally haven’t seen any issues with APC units with compactly in my experience.
If you are on a tight budget then the APC unit will be good but if you can spare a bit more I’d Invest in a pure sinwave unit as it a UPS will last you for many years to come.
