Mini-box Develops Credit Card Size PSU

Inspired by VIA’s unprecedented success in small form factor native x86 mainboard development, has addressed one of the most difficult aspects of designing and building small, attractive PC systems: the power supply unit.

The diminutive Mini-box PW-120 power supply costs US$49.95 and is ideal for small PCs such as thin clients and sleek PCs where industrial design is important and space utilization is at a premium. Its totally fanless, silent performance enables PCs to be used in new environments, such as living room media centers and in hospital or other sound and airflow-sensitive settings. Its light weight and ability to draw power from a 12-volt battery enables breakthrough technologies such as robots and car PCs to operate untethered.

Tiny, cool and silent, yet powerful Minibox Power Supply

Measuring just 2.4″ x 2.25″ and 1U compliant, the PW-120 was designed to fit VIA’s Mini-ITX EPIA-M and EPIA-MII mainboards that target living room digital entertainment devices. The 12Volt PW-120 DC to DC converter delivers an impressive 200 watts and is 25% smaller than a credit card, allowing for unprecedented design flexibility for aesthetically pleasing consumer electronics style system designs. With an efficiency rate of over 95%, the PW-120 can power the most demanding Mini-ITX system configuration, making it the ideal PSU solution for any media center or embedded server application.

Reduces Space — no more messy cables

By eliminating traditional 20 ATX power extension wires, the PW-120 snaps directly into any ATX power connector. Designed from the ground up to fit the Mini-ITX form factor, the PW-120 enhances VIA’s small form factor initiative by drastically reducing the size of a fully functional PC.

The PW-200-V model delivers the same amount of power, under a different form factor, specifically designed for the EPIA M, PD, MII and the soon to be released MS and SP boards. as well as Pentium-4 3.0Ghz-equipped motherboards.

Dane Glasgow, co-founder of Project Colimbo,, a completely amateur effort advancing space exploration through the development of a low cost, low earth orbit payload delivery system, confirmed early tests of the new Mini-box power supply: “At Project Colimbo we have strict requirements for size, weight and power consumption of our onboard systems. The Mini-box PW-200-V fits our needs perfectly through a combination of its small form factor and high efficiency. Additionally, it reduces the overall system weight by eliminating the need for any large multi-wire power cables.”

“The PW-120 suits the needs of everyone from case modders to designers of important commercial products such as point of sale terminals and car and boat PCs,” said Mini-box CEO, Andrei Bulucea. “Together with the VIA Mini-ITX form factor mainboard, designers of any PC device that requires freedom from traditional AC connections yet requires power and silent operation will find new exciting possibilities with the PW-120.”
