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

Volts (V) 5V 5VSB 3.3V -12V 12V

Power Ratings

Max Load (A)	Peak Load (A)	Regulation %
6A	7A	+/- 1.5%
1.5A	2A	+/- 1.5%
5A	7A	+/- 1.5%
0.05A	0.1A	+/- 5%
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.

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.
