Manufacturer description
The NZXT Internal USB Hub 3 solves a problem most builders hit the moment they add a liquid cooler, an RGB controller, and a fan hub to the same system: your motherboard runs out of internal USB 2.0 headers. This hub takes a single motherboard connection and turns it into four internal USB 2.0 ports, so your AIO pump, lighting controller, and fan accessories can all stay wired without swapping components in and out. Power comes from a SATA connector rather than being pulled through the header, which keeps the supply to those four devices stable. Installation is deliberately low-effort. The…
SpecPicks Verdict
SpecPicks scored NZXT Internal USB Hub 3 using a rating × review-volume × price-fit model applied to published specs and reviews across the external storage category. NZXT's external storage lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.

Frequently Asked Questions
How many USB ports does the NZXT Internal USB Hub add?
It adds four internal USB 2.0 ports from a single motherboard connection, for a net gain of three usable headers over the one it consumes.
Does it need its own power?
Yes. The hub uses a SATA power connection from your PSU to provide a stable power source to the four ports, so plan for one spare SATA lead.
Will this work with USB 3.0 devices or headers?
No. This hub expands USB 2.0 only. It is built for AIO liquid coolers, fan controllers, and lighting accessories that use internal USB 2.0 connections.
How do you mount it inside a case?
The body is magnetic and NZXT includes 3M dual lock tape, so it attaches to a steel case panel or behind the motherboard tray without screws or brackets.
Do I need to install drivers or NZXT CAM?
No. It is plug and play, with no driver or software install required for the hub itself.
