Key specifications Model numbers: PA11813HB, D18180P1A Adapter part numbers: L07658001, L08404002 Maximum output power: 180W Output: 12.1V at 14.88A AC input: 100240V AC, 2.3A, 5060Hz Connector: 4Pin plus 4Pin plus 7Pin slimline connector CPU power connector: 4 pin PFC type: Active Fan: single internal fan for controlled cooling Design: nonmodular Why choose this power supply Stable 12V power delivery: A dedicated 12.1V rail rated at 14.88A supplies consistent power to CPU and system components, reducing voltage fluctuation under typical desktop loads. Wide AC input range: Works with 100240V AC mains and 5060Hz frequency, making it suitable for diverse power environments. Compact, practical design: Nonmodular layout and slimline connector help fit smaller chassis and compact desktop systems where space is limited. Active power factor correction: Improves input current waveform for more efficient conversion and smoother operation. Singlefan cooling: Provides airflow while maintaining a low profile suitable for small form factor enclosures. Compatibility and connectors Slimline 4Pin+4Pin+7Pin connector and a 4 pin CPU power connector support common desktop motherboard layouts and power adapter configurations. Compatible adapter part numbers L07658001 and L08404002 are supported for systems that require those adapters or replacement parts. Typical use scenarios Replacing a failed power supply in a compact desktop or small form factor workstation that requires a 12V 180W unit. Powering an embedded PC or dedicated terminal where a reliable, singlerail 12V supply with active PFC is preferred. Upgrading a mini workstation to improve power stability for components that draw on the 12V rail, while maintaining a lowprofile installation. This power supply is intended for desktop applications requiring a compact, nonmodular unit with a 12.1V output at up to 180W, active PFC, and slimline connector compatibility with adapters L07658001 and L08404002.
