NZXT Internal USB Hub Gen 3

This NZXT AC-IUSBH-M3 hub adds four USB 2.0 ports to a single motherboard header so builders can connect liquid coolers, fan controllers and lighting accessories without running out of headers. It draws power from a SATA connector for stable delivery and measures 41mm by 82mm by 14mm without pins, or 20mm with pins, allowing it to be tucked away in tight builds. Magnetic mounting and 3M Dual Lock tape make installation quick and tool-free. The black plastic and PCB construction keeps the unit lightweight and discreet inside any case.

Builders who need extra USB 2.0 headers

This hub suits anyone whose motherboard lacks enough USB 2.0 headers for multiple internal devices such as AIO coolers or RGB controllers. It is not for users who require USB 3.0 or higher speeds because every port and the upstream connection are limited to USB 2.0. It also does not help if your power supply lacks a free SATA connector, since the hub needs that 5 V DC rail for reliable operation. Systems with no spare header at all cannot use this product because one header is required for the upstream link.

Single USB 2.0 motherboard header input

The deciding specification is the single USB 2.0 header that connects the hub to the motherboard; if your board has no free USB 2.0 header this hub cannot be installed. Four downstream USB 2.0 ports then become available for internal peripherals. Power is supplied through a standard SATA connector, so a spare SATA power lead is also necessary. No other interface or protocol is involved, and the hub does not convert or upgrade the signal to a newer USB standard.

Questions about this item

Will this hub work with my existing USB 2.0 liquid cooler and fan controller?

Yes, the four internal USB 2.0 ports accept any standard USB 2.0 device such as liquid coolers, fan controllers or lighting accessories.

How can I verify the hub is receiving power and passing data after I install it?

Connect the SATA power cable, then check in your operating system or motherboard BIOS that each attached device appears on the USB 2.0 header.

Does the package include the SATA power cable and mounting tape, or do I need to buy them separately?

The hub has a built-in SATA power connector and comes with 3M dual lock tape and a magnetic body for mounting; no extra cables or adhesives are required.
