Direct Replacement Power Supply

This 180W unit is a direct drop-in replacement for the original PA-2181-1 power supply used in specific Lenovo desktops. It cross-references OEM part numbers HK280-21PP, HK280-23PP, PCE027, and PCE028. The adapter fits models including W4095c, M4200f-00, M4601c, M4900c-00, T4900d, and T6900c without case modification. It is built for office, POS, and business desktop fleets needing a reliable spare.

Fixed Connector Limits Upgrades

The power supply uses a fixed wiring harness with a proprietary 10PIN mainboard connector and a dedicated 4PIN CPU power plug. Pin definitions and cable lengths match the factory original unit for plug-and-play installation. This exclusive connector layout means the unit cannot support motherboards requiring standard 24PIN ATX or 8PIN EPS connections. It is unsuitable for builds needing modular cables or higher wattage headroom for discrete graphics cards.

Certified Efficiency and Protection

The adapter carries 80Plus certification with Active PFC across a universal 100-240V AC input range. It delivers stable output on a single +12V rail with full OVP, OCP, SCP, and OTP protection circuits. UL, CE, FCC, and RoHS certifications confirm compliance with safety and environmental standards. An intelligent speed-adjust cooling fan and industrial-grade capacitors support continuous 24/7 operation in compact chassis. Standard ATX mounting holes align with the original case for secure installation.

Questions about this item

Which connector version matches my Lenovo desktop?

The adapter ships with a fixed 10PIN mainboard connector plus a dedicated 4PIN CPU plug wired to the original PA-2181-1 pinout, so it fits the listed W4095c, M4200f-00, M4601c, M4900c-00, T4900d and T6900c chassis without modification.

What does the 180W rating mean for daily office use?

It delivers a continuous 180W on a single +12V rail, enough to run an office-grade CPU, integrated graphics and multiple hard drives simultaneously under 24/7 operation.

What AC input standard does the unit accept and what does that cap?

The universal 100-240V input handles global household and office voltages, while the built-in Active PFC and 80Plus certified efficiency limit standby draw and keep output stable across that range.
