Lian Li PW-U2HB USB Converter 1 USB to 3 USB

This Lian Li PW-U2HB is a small but useful accessory if you don't have free internal USB 2.0 headers on your motherboard and want to connect additional controllers, hubs, or accessories. Essentially, it is a splitter/hub for internal 9-pin USB 2.0 connectors, turning one header into three. This frees up space for fan controllers, RGB hubs, or other internal devices without replacing the motherboard. Its black color helps it blend seamlessly into most builds without drawing unnecessary attention.

What you get

The PW-U2HB accepts one standard 9-pin USB 2.0 connector from the motherboard and provides three internal 9-pin outputs. This is especially useful if you use several fan and RGB controllers that all require internal USB for software control. Instead of choosing which device to sacrifice, you simply branch the available header and maintain full functionality of the case and accessories. Controlling up to 3 fans via the connected controller becomes easier because you have enough internal USB ports to connect everything properly.

• Works as a fan splitter, allowing you to connect multiple fan/RGB controllers to a single USB 2.0 header on the motherboard.
• Features Internal USB 2.0 9-pin connectors, making it compatible with the common internal USB headers on modern motherboards.
• The input is 9-Pin USB, and the outputs are 3 x 9-Pin USB, effectively turning one header into three.
• Allows control of up to 3 fans via connected controllers without running out of internal USB ports.
• Classified as a Fan controller, Fan/RGB splitters, so it is designed specifically for scenarios with many fans and RGB devices.
• Compact and in black color, to sit discreetly in the case and not ruin clean cable management.
• Comes with a 24-month warranty, giving you peace of mind for long-term use in daily or gaming builds.

Who it is suitable for

It is suitable if you have a case with many fans, a separate fan/RGB controller, or a pump/reservoir with USB control, and you have already filled the internal USB 2.0 headers. It is ideal for more serious gaming or showcase builds with many accessories that rely on internal USB for software control. If your build is simple and your motherboard has enough USB 2.0 headers, you probably won't need it.

The most sensible aspect of the Lian Li PW-U2HB is that it occupies only one internal 9-pin USB port and returns three, solving a very annoying problem in modern builds with many controllers and RGB, without complicating the configuration.
