Add four USB 3.0 ports with four independent channels, LP/SATA power, and charging support to your PC

USB 3.0

USB 3.0

USB 3.0

The 4-Port PCI Express USB 3.0 Card lets you add four, dedicated 5 Gbps USB 3.0 ports to your PCIe x4-enabled PC.

This independent port architecture improves USB 3.0 performance by transferring data on four individual channels to your computer, giving you faster file transfers.

When multiple devices are connected, traditional single bus USB 3.0 cards share your maximum bandwidth between all ports.

By employing four host controller chipsets, each port operates on a separate independent transmission channel. Dedicating up to 5 Gbps to each USB port reduces performance bottlenecks, and effectively quadruples your total available to bandwidth to 20 Gbps.

Enhanced with UASP support (USB Attached SCSI Protocol), this USB 3.0 controller performs up to 70% faster than conventional USB 3.0 when paired with a UASP supported enclosure (Note: UASP requires a compatible operating system).

For high-power USB devices, this PCIe USB 3.0 card includes an optional SATA or LP4 power connector to connect to your system power supply and deliver up to 900mA of power per port to USB 3.0 bus-powered devices (500mA for USB 2.0).

The USB 3.0 card also supports USB Battery Charging Specification 1.2 (Apple Mode only), letting you charge compatible Apple devices (iPhones and iPads) faster than a standard USB 3.0 port.

Offers backward compatibility with existing USB 2.0 / 1.1 devices. The USB 3.0 PCIe card is equipped with a standard profile bracket and includes a low-profile/half-height bracket for installation in small form-factor computers.

    I have this installed on an ASUS ROG Maximus IX running Windows 10. It seems to be working alright without installing any special drivers.I only have two issues with this board:1. It requires a secondary power connection. I wasn't thrilled to have to run a new power cable through my rig just for this card.2. The molex connector easily pops off the board when attaching or detaching a cable. While I was able to remount it, it could easily pop off the board and damage its connection to the board in the process, so be careful or use the sata power connection instead.The main benefit of the this card is that it uses a separate USB hub for each port, resulting it much better bandwidth and response times across devices. In that respect, it works great!

    In the Windows 10 computer, ready to go. With 2 Elgato and 1 Logitech streamcams no problem. Worked without extra voltage input, I did put an extra voltage in to give the motherboard less stress.

    Works well with OBS etc. No drivers needed.

    No problem with the ports, more then enough space to put in the USB cables. So I don’t know why some have a problem with that.

    Gets a little hot, don’t know how long it will last. If it breaks, I update here.
