These form factors utilize a more efficient Active Power Factor Correction (APFC) power supply. Dell recommends
only Universal Power Supplies (UPS) based on Sine Wave output for APFC PSUs, not an approximation of a Sine Wave, Square
Wave, or quasi-Square Wave (see UPS technical specifications). If you have questions, please contact the manufacture to
confirm the output type.
