Silverstone AD120-DC 120W Fanless Power Supply

Compact Fanless Power Kit

The Silverstone AD120-DC delivers 120 W through a fanless DC-DC board paired with a 12 V 10 A AC-DC adapter. It targets builders of compact systems such as the Milo 10 chassis who need silent operation and a minimal footprint. The black-wire loom includes a 24-pin ATX connector, an 8-pin EPS connector, three SATA connectors and one 4-pin peripheral connector.

Upgrade From Flex ATX Units

This kit replaces bulkier flex-ATX or low-profile internal supplies where space and noise are primary constraints. The jump is worthwhile when the total system draw stays within the 120 W limit and the chassis can accommodate the external adapter brick. Builds requiring higher wattage or additional PCIe power connectors cannot use this solution.

Limits of 12 V DC Input

The DC-DC board accepts a single 12 V input rated at 10 A, capping combined output at 120 W across all rails. Cable lengths are fixed at 200 mm for the 24-pin and peripheral leads, 250 mm for the EPS lead, and 300 mm plus two 100 mm branches for the three SATA connectors. The board measures 160 mm by 45 mm by 25 mm, while the adapter measures 168 mm by 71 mm by 37.5 mm.
