Expanding Connectivity for a Clean Build
First Impressions & Build Quality Upon unboxing the NZXT Internal USB Hub 3, the immediate impression is its compact and sleek design. NZXT is known for its minimalist aesthetics, and this hub follows suit with a black, often magnetic, casing that allows for discrete placement within the PC case. It feels solid and well-constructed, a testament to its durability. The hub typically comes with a single input cable (connecting to one motherboard USB 2.0 header) and multiple output ports (often three or more internal USB 2.0 headers, plus one standard USB Type-A port for external devices if needed). The cables are usually black and flexible, aiding in clean cable management, and the connectors fit securely. The magnetic backing is a thoughtful touch, allowing for easy, tool-free mounting to any steel surface inside the case. Functionality & Performance The core purpose of the NZXT Internal USB Hub 3 is to expand internal USB 2.0 connectivity without compromising data integrity or power delivery, and it performs this task exceptionally well. USB Header Expansion: This is its primary and most crucial function. For motherboards with only one or two USB 2.0 headers, this hub allows you to connect multiple devices that require this connection (e.g., AIO coolers, RGB controllers, fan controllers, front panel USB ports, etc.) Stable Data Transfer: Unlike some cheaper, passive hubs, the NZXT Internal USB Hub 3 is typically an active hub, meaning it draws power directly from the PSU (via a SATA power connector). This ensures stable power delivery to all connected devices and maintains consistent data transfer speeds, preventing connectivity issues or dropped signals that can plague unpowered hubs. Clean Cable Management: By consolidating multiple USB connections into one central hub, it significantly reduces cable clutter around the motherboard's headers. This leads to a cleaner-looking build and can improve internal airflow. Broad Compatibility: It's generally compatible with a wide range of internal USB 2.0 devices from various manufacturers, making it a versatile solution for diverse PC builds. In practice, the hub silently and effectively manages the additional USB connections, allowing all components to function as intended without conflicts or performance degradation. Installation & Placement Installation is remarkably simple. You connect the hub to one available internal USB 2.0 header on your motherboard and plug in a SATA power connector from your PSU. Then, you connect all your internal USB 2.0 devices to the hub's output ports. The magnetic backing is a major convenience, allowing it to be easily mounted to any steel surface within the case – behind the motherboard tray, on a drive cage, or even directly on the PSU shroud. This flexibility ensures a clean, hidden installation, which is a hallmark of good cable management. Areas for Improvement While the NZXT Internal USB Hub 3 is highly effective, a few minor considerations exist: Price: It is typically priced higher than generic, unpowered USB hubs. However, the active power delivery and build quality often justify the cost for reliability and a cleaner aesthetic. USB 3.0/3.1 Limitations: This hub is specifically for USB 2.0 headers. If you need to expand USB 3.0/3.1 internal connectivity, a different type of hub or PCI-e card would be required. This is not a flaw, but a design focus. Redundancy (for some builds): For very basic builds with minimal internal USB devices, this hub might be an unnecessary expense if the motherboard already provides sufficient headers. Its value shines in complex or aesthetic-focused builds. Cable Lengths: While generally good, in very large cases, the included cables might sometimes be a stretch to reach desired mounting locations, though this is rare. Conclusion The NZXT Internal USB Hub 3 is an elegantly designed and highly functional solution for PC builders grappling with a shortage of internal USB 2.0 headers. Its robust build quality, active power delivery for stable performance, and thoughtful magnetic mounting make it a superior choice compared to passive alternatives. While it comes at a slightly higher price point, its ability to streamline cable management and ensure reliable connectivity for numerous internal peripherals makes it an invaluable component for clean, modern, and complex PC builds. For those seeking to expand their internal USB connectivity without compromise, the NZXT Internal USB Hub 3 is a highly recommended and insightful upgrade.

Perfect for boards with only one 9-pin header
Works great, exactly what I needed for multiple USB header devices and only one board connector.

Very solid and well made
Installed easily and had my PC running again in less than 5 minutes. I like the solid construction of this over my previous internal hub, which started to give repeated USB connect / disconnect notifications. Even the provided USB cable to connect to the motherboard is thicker. I installed this and my USB issues were fixed.

Great hub
I needed a USB hub that would allow me to run all of my bling-bling that required dedicated USB ports; there were only two USB ports on the motherboard. I tried other USB hubs and none were able to support these devices, but this hub did. It works awesome!

Great internal USB hubs
These are great to add accessories inside your case. Magnet mount and hold great wherever you put them! Well worth the extra cost vs no name brands

Would be better if the pins were recessed
Overall, this product works, it let me hook up several USB devices with only using one USB Header. My motherboard only has two USB ports and I needed 4, so this was perfect for my needs. The magnet at least keeps it from sliding when on top of a flat surface, but it wasn't strong enough to attach it to the top of the case, and I didn't feel it was stable enough to stay put on a vertical surface. Fortunately, I had a good spot under the PSU with enough clearance for it to sit. My main concern is that the pin start flush with the casing and this seems like a potential easy breaking point. I didn't have any issues with it, but I'd have felt safer with it if the pins were recessed in a boot like they have on the motherboard or down into the case itself to better protect them.

Worked just as it should
Worked really good when I started to have a lot of fans and coolers on my build. Easy to set up.

Great for Lian Li
Works great for connecting all the Lian Li SL and TL fans! Very high quality build, and looks great. It also comes with plastic covers to protect the USB pins you aren't using.

Was sceptical about purchasing this after reading some questionable reviews. I searched all over the internet for other internal hubs as I don’t have enough usb 2.0 headers in my board and it turns out options are extremely limited so I decided to bite the bullet and get this one. The unit was extremely easy to set up just plug it into your usb header and then connect it to your psu and you’re left with four ports total. No need for adhesive tape as this unit is magnetized which is great. I was able to hook up my Aio/fans/led case strip with this Nzxt internal hub. Will update if anything changes but so far unit is working exactly how it should. 5/5 recommend.
