As applies precisely to this thread and wattage rankings, a PSU with Energetic power component correction may well really draw extra power when needed to appropriate for misaligned you can try here current. This is achievable anytime as power shipping is rarely best, but far more very likely when The existing is Using a squared off wave.
If the pc components won't use an Energetic PFC power supply, utilization of a modified sine wave UPS is not really a problem (and implied, utilization of a pure sine wave UPS is not really a advantage).
