Introduction
The picoPSU-120 is a small yet powerful and fully compliant ATX
power supply designed to power a wide variety of motherboard from a
single 12V regulated power source.
The PICOPSU-120 is the only snap power supply solution for general
purpose motherboards. Compatible with an entire range of mini-ITX,
UATX or full size ATX motherboards the picoPSU-120 provides cool,
silent power for system. The PICOPSU-120 has many advantages
over a regular power supply:
-Smallest ATX PSU to date
-100% silent operation
-Low heat dissipation with efficiency over 95%
-Plugs directly into the motherboard’s power connector, no cable mess
Quick installation Instructions
The PICOPSU-120 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 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.
2) Connect a 12 VDC power adapter (or any 12V source) to the DC-to-
DC connector, center pin / white wire is positive (+).
3) Turn on the PC using the motherboard ON/OFF switch

Typical configuration
The picoPSU-120 has been tested with all mini-ITX board under
virtually any disk/floppy/CDROM/PCI configuration. Additionally, the
PICOPSU-120 can power P4 boards. Some P4 boards require a
P412V connector. Please check for a cable http://www.mini-box.com
harness adapter or solder a P4 cable harness into the 12V, 5V and
GND pads on your ATX connector.
Removing the picoPSU-120
In order to remove the picoPSU you must release the power connector
latch and then remove the unit. Gently lift the picoPSU out from the
ATX connector, by grabbing from the picoPSU PCB, not from
components or the wire harness.
