Contact us for availability

The picoPSU-120 plugs directly into a motherboard ATX connector and measures just 43 x 20 x 31 mm - about the size of two AA batteries. The picoPSU-120 generates up to 120 Watts of power from a 12V DC supply, at over 96% efficiency. An attached cable harness provides:

  • 20pin ATX Connector
  • SATA Power Connector
  • Molex (ATA) HDD Power
  • Molex Floppy Power

Legacy Device: Although this unit is still available, the picoPSU-90, picoPSU-150-XT and picoPSU-160-XT may be better choices for you.

Compatibility: The picoPSU-120 can power all our Mini-ITX boards e.g. Celeron but also earlier Geode, C3, C7, Atom and Fusion processors. Additionally most lower power consumption Mini-ITX boards with Intel and AMD processors up to around 65W TDP can be powered. More powerful picoPSUs offer more headroom for additional devices. If you are considering using with a board not on our site, please email us to check compatibility.

12V AC Adapter Required: You will need a 12V AC Adapter to use this picoPSU. Please read their product listings to determine which is most suitable for you. Compatible Universal AC Adapters:

*The 2.5/5.5mm Jack can be replaced with the more robust 4-pin Mini-DIN connector that is supplied with our 150W and 192W AC Adapters.

Adding more SATA drives: The picoPSU-120 has one SATA connector and a Molex connector. To power more SATA drives use a Molex to SATA or 2x SATA cable.

P4 Power Connectors: If your board has a 4-pin 12V P4 power connector, you will need to use a Molex to 12V P4 Power Cable, or a picoPSU-90 or 150/160-XT.

Long Life: The picoPSU-120 with Mini-Fit JR is marked for long life production and is guaranteed to have a life cycle of 5 years or more.

Notes: Not suitable for use with batteries, unstable power sources or voltages other than 12V.

CE / FCC / VCCI Certifications: EN55024, EN55022 Class B (CE certification), Australia/New Zealand (using CISPR 22, EN55022), Japan (VCCI: using CISPR 22, ANSI C63.4), United States (FCC Part 15, Subpart B, Class B), Canada (ICES-003 using CISPR 22, ANSI C63.4).
