I'm debating whether to get a "online UPS" system or a "pure sine wave UPS" system. The brand is tripp-lite both are 1500VA. The online UPS is 810W and the Pure Sine Wave UPS is 900W. I will be using this just for computer use. Playing games, watching movies, data backup on external devices (expensive nvme, SSDs and HDDs over 20TB in two full docking bays). It's a Windows gaming laptop worth over $2K with dual Dell monitors. This is why I'm considering getting a UPS setup. More importantly to avoid unexpected power grid failures/ brownouts and blackouts without saving my work or shutting down properly.
From what I read regular UPS systems is suffice. I think the extra dollars for the pure sine wave is for "sensitive" electronics. But what electronics is not sensitive? I feel it's a gimmick. But as for someone who does not own a UPS or a pure sine wave UPS yet I don't know for sure. Does anyone own a pure sine wave or a regular online UPS setup? The price difference isnt far off as Amazon sells the tripp-lite UPS for $182 and the Pure Sine wave for $186. Which now leaves me to think it's not much difference. The purity of power seems gimmicky will I go wrong choosing a regular UPS rather than a pure wave?
Thanks for any help.
