Drop-in SFF replacement

This 260W power supply is a direct OEM replacement for HP and Lenovo 510S, M420 and 700-24AGR small form factor desktops. It matches original part numbers PA-1261-7, PA-1181-7, PCK027, PCH018 and SP50H29606. The standard slim dimensions allow installation without chassis modification. A complete wiring harness with 6Pin mainboard and 4Pin CPU connectors enables plug-and-play setup.

Sustained 260W delivery

The unit provides a stable rated 260W continuous output rather than a short burst rating. Built with high-grade components following original factory specifications, it maintains steady power for daily office computing, document processing and regular home desktop workloads. Multi-protection circuits including OVP, OCP, SCP and OTP safeguard the CPU, motherboard and storage against power surges during extended operation.

Thermally controlled fan

A variable speed cooling fan automatically adjusts rotation speed to minimise running noise while optimising heat dissipation. This thermally controlled design supports effective heat management and a long operational lifespan for typical daily use. The slim form factor fits the original enclosure without restricting airflow or requiring case alterations.
