Is Your Lenovo Desktop Having Power Issues? Here‘s Your 180W Replacement Guide

Connector Configuration – The Most Important Check
This power supply uses a Lenovo proprietary 14-pin motherboard connector. Do not attempt to use this on a standard ATX motherboard.
| Interface Type | Connector | Quantity |
| Motherboard Main Power | 14-pin (proprietary) | 1 |
| CPU Power | 4-pin | 1 |
⚠️ Special Note: This power supply has no SATA connectors. It is designed specifically for Lenovo systems that draw power for drives directly from the motherboard. Please verify your system‘s drive power requirements before ordering.
Why This Connector is Different:
Standard ATX power supplies use a 20-pin or 24-pin motherboard connector. Lenovo uses a proprietary 14-pin connector with a different pinout and smaller physical size. Do not attempt to force a standard ATX power supply into this motherboard.
Physical Size – Measure Before You Order
Even if the model number matches, it‘s always a good idea to check the size.
| Dimension | Measurement |
| Length | 15 cm (150 mm) |
| Width | 10 cm (100 mm) |
| Height | 8.5 cm (85 mm) |
This specific size is designed to fit perfectly inside Lenovo desktop chassis that use this proprietary form factor.

- Disconnect cables from the old power supply – note where each connector goes (14-pin main, 4-pin CPU).
- Take a photo of the connector layout before disconnecting – this is critical due to the proprietary 14-pin connector.
