PicoPSU-150-XT 12V 150W ATX power supply

This new DC-DC ATX unit clips directly into the motherboard 24-pin socket, eliminating the bulk of a standard PSU. Solid polymer capacitors from Japan and over 96% efficiency support long-term reliability in a completely fanless design.

Builders needing a tiny silent ATX supply

It suits compact systems that run on a 12V external brick and have modest power requirements. Builds requiring more than 150W, multiple high-current 12V rails, or an integrated AC inlet should consider a different form factor.

150W ceiling defines comfortable loads

The supply powers modern low-TDP processors, integrated graphics, storage drives and essential peripherals within its 150W envelope. Exceeding this limit risks instability, so total system draw must stay below the rated maximum.

Questions about this item

What external DC source do I need to feed the 12 V input on this PicoPSU-150-XT?

A 12 V DC power brick or battery capable of supplying at least 150 W is required; the unit converts that input to ATX rails for the motherboard.

Will the 24-pin ATX connector on this PicoPSU-150-XT fit my older motherboard that still uses a 20-pin socket?

The 24-pin plug is keyed so the extra four pins can overhang a 20-pin socket; it will seat correctly as long as the board follows the ATX layout.

How can I confirm the PicoPSU-150-XT is delivering power after I clip it into the motherboard?

The system will POST and the operating system will load; with no fan the only audible sign is silence, so a successful boot is the practical verification.
