In the event the UPS labored high-quality in maintaining points run up in the course of outages, you won't need to be worried about the waveform challenge or need a costly pure sine wave UPS.
Irrespective of whether you utilize the fewer specific or maybe more exact system, you'll have a wattage value. For our calculation examples, We will use 400w as our price.

Where by this UPS will come in handy is as a device for very low-electrical power PCs and consoles. Many prebuilt HTPCs and Office environment PCs, For example, should have Significantly reduced wattages compared to the 390W goal demanded by this device.
This is largely the real-globe Variation with the idealized waveform shown in fixer1234's answer. The answer to my problem previously mentioned, then, is "Yes, they really do make UPSes with output excellent that undesirable."

A vintage example of a tool that starts off with these kinds of an assumption is definitely an analog audio ability amplifier developed in or before the early 1970s, or a far more fashionable piece built alongside precisely the same strains. Linear regulation throws off an excessive amount heat for being recommended reading sensible in such a device, lower-sound switching regulation engineering wasn't seriously offered at some time, and so amps of that point have been created with essentially unregulated power instantly driving the amplification stages.
For reference, This is certainly just what the unfiltered AC line voltage appears like on the exam area, with voltage vs time within the left along with a spectrum plot of exactly the same waveform on the appropriate:
PC electric power use is perfectly less than 400W, Despite having high-conclude elements. Contemporary PCs Specifically have lower electric power needs– my own Computer at max load shouldn't ever exceed 310 Watts, For example.
Switch the battery, not the unit: Like all electronics, a UPS gained’t previous without end. But Preferably, you have to be equipped to replace the battery many periods before You must exchange all the device.
