Lian Li USB 2.0 1-to-3 Internal Hub
The Lian Li USB 2.0 1-to-3 Hub (Model: PW-U2HB) converts a single motherboard 9-pin USB 2.0 header into three independent ports. Connect up to three RGB controllers — including UNI FAN and STRIMER PLUS V2 — simultaneously, even when your motherboard has limited USB headers. Built-in signal stabilization ensures interference-free data transmission for all connected devices.

Key Features
🔌 Expand Your RGB Ecosystem
Despite limited motherboard USB headers, this hub converts one USB 2.0 9-pin header into three fool-proof ports. Connect two types of UNI FAN controllers and a STRIMER PLUS V2 simultaneously — all from a single motherboard header.
📶 Stable Signal Transmission
The built-in chipset stabilizes signals across all connected devices, ensuring interference-free data transmission. No more dropped connections or erratic RGB behavior when running multiple controllers.
🔧 Simple & Flexible Installation
Featuring Velcro straps on the hub to route cables in tight spaces. Extra long cables (140mm each) allow clean routing in large cases through the second chamber. Includes an adhesive magnetic pad for secure mounting.
Compatible Lian Li Controllers
The hub works with the following Lian Li controllers. Connect up to three simultaneously from a single motherboard header.
Technical Specifications
Who Should Use This Hub?
✓ Best For
- Builders with multiple Lian Li RGB controllers (UNI FAN, STRIMER)
- Systems where the motherboard has limited USB 2.0 headers
- Enthusiasts wanting a clean, cable-managed RGB setup
- Builders using large cases requiring extended cable routing
- Users who want stable signal transmission for multiple devices
Consider Alternatives If
- You need to connect non-Lian Li devices — compatibility is not guaranteed
- You require USB 3.0 or faster connectivity (USB 2.0 only)
- You only need to connect a single controller (no expansion needed)
- Your motherboard already has enough USB headers
🔧 How This Hub Solves Your USB Header Shortage
The Problem
Modern motherboards typically offer only 1-2 internal USB 2.0 9-pin headers. When building a high-end system with multiple RGB controllers — such as UNI FAN SL, UNI FAN AL, and STRIMER PLUS V2 — you quickly run out of ports. This forces you to choose which controllers to connect, limiting your RGB customization options.
The Solution
The Lian Li USB 2.0 1-to-3 Hub converts a single header into three. Connect up to three controllers simultaneously from one motherboard port. The built-in chipset stabilizes signals, ensuring all connected devices communicate reliably without interference.
Installation Made Simple
- Connect the male 9-pin connector to your motherboard’s USB 2.0 header
- Plug your controllers into the three female ports
- Use Velcro straps for neat cable management
- Mount with the adhesive magnetic pad anywhere inside your case
Pro Tip
For builds with extra-long cable routing needs, the hub’s 140mm cables provide enough length to reach the second chamber of large cases, keeping your main compartment clean and airflow unobstructed.
Common Questions
What controllers are compatible with this hub?
The hub is compatible with: UNI FAN SL Controller, UNI FAN SL V2 Controller, UNI FAN AL Controller, UNI FAN SL-INF Controller, and STRIMER L-Connect 3 Controller.
Will this work with non-Lian Li devices?
While user reports suggest it may work with some third-party devices, compatibility is not officially guaranteed. The hub is specifically designed for Lian Li controllers and their standard 9-pin USB 2.0 connection protocol.
Does the hub require external power?
No. The hub draws power directly from the motherboard’s USB 2.0 header, requiring no additional power connections.
How do I mount the hub inside my case?
The hub includes an adhesive magnetic pad for easy mounting on any steel surface inside your case. Additionally, Velcro straps allow you to secure cables neatly, even in tight spaces.
