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 6A 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 operation de-rate the output of the 3.3
and 5V rails by ~25%. Peak load should not exceed 120 seconds. Combined power output
should not exceed more than 90watts.
