Introduction
The picoPSU-120-WI-25 is a small yet powerful and fully compliant 
ATX power supply designed to power a wide variety of motherboard 
from a single 12-25V unregulated power source.
The picoPSU-120-WI-25 is the only “plug-in” wide input range power 
supply solution for general purpose low power motherboards. 
Compatible with most VIA C3/C7 CPUs M/B and with Pentium-M / 
Core Duo boards, picoPSU-120-WI-25 provides cool, 100% silent 
power for your system. The PICOPSU-120-WI-25 has many 
advantages over a regular power supply: 
-Smallest ATX PSU to date
-100% silent operation
-Low heat dissipation with combined efficiency over 94%
-Plugs directly into the motherboard’s power connector, no cable mess 
Quick installation Instructions
The PICOPSU-120-WI-25 has been specifically designed for the Mini-
ITX form factor, thus eliminating the need for ATX power cables. It is 
also 1U compliant – height will not exceed the 1U formfactor.
 
1)
After the picoPSU module was ‘snapped in’, hook the hard 
drive power or floppy power to your floppy/hard drives. If 
more hard drives or floppy connectors are needed, use a 
HDD/floppy “Y” splitter cable.
