picoPSU-90
12V, 90Watt ATX Power Supply
Quick Installation Guide
Version 1.0d
P/N picoPSU-90
Introduction
Based on the electrical design of the picoPSU-120, the picoPSU-90 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-90 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-90 provides cool, silent power for system. The
PICOPSU-90 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-90 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 form factor.
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 motherboard switch
Typical configuration
The picoPSU-90 has been tested with all mini-ITX board (VIA C3, VIA C7, low
power AMD and Atom) under virtually any disk / floppy / CDROM / PCI
configuration. Additionally, the PICOPSU-90 can power low boards equipped
with an 12VATX 4 pin connector. NOTE: The hard drive cable harness can be
disconnected in case the user does not need any peripheral. Additionally, the
cable harness can be made to any length or output connector type provided that
the max load does not exceed 3A for GND return. Please look under
specifications for the mating connector type.
Removing the picoPSU-90
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.

Specifications, picoPSU-90, 90Watts DC-DC ATX Power Supply
Power Ratings
Volts (V) Max Load (A) Peak Load (A) Regulation %
5V 6A* 7A +/- 1.5%
5VSB 1.5A 2A +/- 1.5%
3.3V 5A* 7A +/- 1.5%
-12V 0.05A 0.1A +/- 5%
12V 5A 7A Switched input
*At max load, forced air ventilation is required. For fanless or improper ventilation operation de-
rate the output of the 3.3 and 5V rails until PSU temperature falls below 65C. Peak load should
not exceed 60 seconds. Combined max power output should not exceed more than 90watts.
Efficiency Ratings, 3.3 and 5V rail
CH1=5V Efficiency (%) CH2=3.3V Efficiency (%)
1A 86% 1A 85%
3A 95% 3A 94%
5A 93% 5A 92%
7A 85% 7A 85%
Input Requirements: 12V regulated, min=1A, max=10A (load dependent). Over-
voltage shutdown will occur at ~13-13.5V.
Size: 44.5mm(L) * 20mm(W) * 30mm (H) (1U compliant)
Weight: 45gramms, including cable harness, 20 grams without cable harness.
DC-Jack: Female, panel mount, 2.5*5.5*10 mm.
Connectors
Molex 39-01-2200 compatible, two 3.5” drive power connectors (PATA and
SATA) and one P4-12V 4 connector (mini-fit JR 4p). Header and mating
connector for the removable cable harness can be found at: http://www.jst-
mfg.com/product/pdf/eEH.pdf
Overload protection
Over load protection will be effected when either of the loads (+5V & +3.3V)
exceeds > 150% Max Load.
Turn-on Delay
After turning on, at least 20 ms will be needed for the rise of +5VSB output
voltage (measured from 10% to 95%) to reach its peak.
Remote ON/OFF control (PS_ON)
Logic level is LOW - Output voltage is enabled (PS_ON pin)
Logic level is HIGH - Output voltage is disabled (PS_ON pin)
PWR_GD
Logic level is low: PWR_GD=OK
Logic level is high: PWR_GD=not OK (10.5V<V(in)>13.5V or other fault
conditions)
