NOTE: 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. If you have
questions, please contact the manufacture to confirm the output type.
