SpecPicks Verdict

SpecPicks scored UCCKEYI ATX Power Adapter Module Board using a rating × review-volume × price-fit model applied to published specs and reviews across the power supplies category. UCCKEYI's power supplies lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.

Common buyer scenarios for power supplies of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase. Prices and stock are set by the retailer and may have moved since this page was last updated.

Key Features

  • Compatibility with 20-pin and 24-pin ATX power supplies ensures seamless integration with most desktop computers. The toggle switch provides convenient manual operation without requiring external control systems.
  • Outputs five essential voltage levels (+12V, -12V, 5V, 5VSB, 3.3V) in a single compact module, eliminating the need for multiple power adapters. The voltage display screen enables real-time monitoring of power supply output for precise system management.
  • High-current terminal blocks provide secure connections that prevent loose wires and difficult wiring issues common with screw-type terminals. The DC female connector functions as both input (12V-24V) and output, offering versatile power configuration options.
  • Includes reserved XH2.54-2P terminals for connecting two external wires controlled via microcontroller I/O ports (5V) or switch for power on/off functionality, ideal for enclosure modifications and custom projects.
  • Features three USB outputs including one fast-charging port (5-12V, 2A) and one Type-C port (5-9V, 2A) supporting PD 2.0/3.0 protocols. Supports powering smartphones, tablets, power banks, and various electronic devices directly.
