Is Your Lenovo TFX Desktop Having Power Issues? Here‘s Your 180W Replacement Guide
If you own a Lenovo Qitian (M series), Tianyi 510, or H3060/G5060 desktop with a TFX form factor power supply and are experiencing power failures, random shutdowns, or simply need a spare PSU, you’ve come to the right place.
Lenovo TFX desktops use specific power supply designs that are different from standard ATX units. Finding the correct replacement can be challenging because these units use proprietary 10-pin connectors and the TFX form factor.
This guide will help you quickly identify if the 180W PA-2181-2 Power Supply is the right match for your Lenovo computer.

| CPU Power | 4-pin | 1 | 60 cm (ultra-long) |
⚠️ Special Note: This power supply uses a proprietary 10-pin Lenovo TFX connector – not the standard 24-pin ATX connector. Do not attempt to use this on a standard motherboard.
Ultra-Long CPU Cable – A Key Feature
