As applies exclusively to this thread and wattage scores, a PSU with Energetic power factor correction may possibly in fact draw extra power when required to suitable for misaligned present. This is achievable at any time as power delivery isn't excellent, but way more probably when The existing is Driving a squared off wave.
If the computer hardware will not use an Active PFC power supply, use of a modified sine wave UPS just isn't a problem (and implied, use of a pure sine wave UPS just isn't a advantage).
