PS/2
This specification describes the requirements 550W/650W/750W switching
power supply with an stretch ATX form-factor and EPS 12V, +5V standby voltage,
remote on/off control,full range line input capability and forced air cooling characteristics.
1.0 AC INPUT
1.1 AC input requirements
The input voltage, current, and frequency requirements for continuous operation are
stated below.
Parameter Min Nom Max Unit
Vin 90 100 ---- 240 264 VACrms
Vin Frequency 47 60 ------- 50 63 Hz
Iin(550W) 8.0 ----- 4.0
Iin(650W) 9.0 ----- 4.5
Iin(750W) 10.0 ---- 5.0
Power factor correction (PF)>0.9 at full load.
1.2 Inrush current regulation
The power supply must meet inrush requirements for any rated AC voltage, during turn on at any
phase of AC voltage, during a single cycle AC dropout condition, during repetitive ON/OFF
cycling of AC,and over the specified temperature range (Top). The peak inrush current shall be
less than the ratingsof its critical components (including input fuse, bulk rectifiers, and surge
limiting device).

2.3.2 Definition
The ripple voltage of the outputs shall be measured at the pins of the output connector when
terminated in the load impedance specified in figure1.Ripple and noise are measured at the
connectors with a 0.1uF ceramic capacitor and a 10uF electrolytic capacitor to simulate system
loading. Ripple shall be measured under any condition of line voltage, output load, line frequency,
operation temperature.
