Introducing the picoPSU, the world's smallest 12V DC-DC ATX power supply unit (PSU)!

Small computer projects start with small power supplies. picoPSU is a crucial key component that unleashes the ultimate power solution for general purpose computing platforms. picoPSU is fully ATX compliant, making it an excellent candidate for any silent, 12V DC-DC computer project.

Compact Design. The picoPSU is the smallest ATX DC-DC power supply in the market. By using patent pending HyperWatt™ technologies, picoPSU packs an impressive amount of power relative with its very small footprint.

Reduced Space. Eliminate up to 20 unnecessary wires by plugging in directly into the motherboard ATX connector. The picoPSU 12V DC-DC ATX converter was designed from ground up to fit small form factor ATX boards, allowing enclosure designers to save space while not compromising power requirements. The picoPSU provides plenty of power (via ATX connector and HDD cable harness) for CPU and an entire range of peripherals.


Cool Power Operating at only 12V, the picoPSU DC-DC ATX power supply generates 90 watts of power. The picoPSU provides a cool running, silent 90 watts of power for small PC designs using a single 12V power source.
