DC-DC ATX Power Supplies


Ideal power for small form factor boards (mini-ITX, nano-ITX, etc). Small form factor computers (mini-ITX PCs, car PC, appliances) start with smallest, 100% silent fanless switching DC-DC ATX PC mini power supplies (PSU). Select from a range of high efficiency plug-in small PC power supplies modules in a variety of power outputs, footprints and input voltage ranges such as 12V DC, wide input 6-24V DC for car PC and solar or battery use, with all necessary ATX outputs (3.3V, 5V, 12V, -12V, 5VSB) and ATX signaling (PS_ON, PWR_OK, etc).

Due to ultra-compact design (picoPSU is world's smallest PC power supply), our mini DC-DC ATX PSUs plug directly into the motherboard's 20 or 24 pin ATX power supply connector, eliminating the need of a ATX extension cable harness. Power an entire range of motherboards, starting from VIA mini-ITX boards all the way up to Pentium / Celeron, Core Duo or AMD small form factor or fanless PC systems.

If looking for a high efficiency power supply to power a PC (car PC) in a car or vehicle or battery solar use, look at our M-series small ATX PSUs, designed to work in car environment with voltage ranging from 632V.
Also for wide input voltage applications such as batteries, please look at our pico-PSU-60WI, a 6-26V input range ATX DC-DC power supply unit, specifically designed for mini-ITX board equipped 20 or 24 pin ATX connector.

All our DC-DC ATX small form factor fanless ATX PC power supplies and car PC power supplies are designed and manufactured by us.
