Before you settle for less, consider the PEXUSB3S42V 4-Port PCI Express USB 3.0 Card, a high-speed, reliable solution for expanding your computer's connectivity. This compact and versatile card allows you to add four USB 3.0 ports with two dedicated 5 Gbps channels to your PCIe x4-enabled PC, enhancing your system's performance and versatility.Unlike traditional single bus USB 3.0 cards that share your maximum bandwidth between all ports, this card employs an independent port architecture. This design improves USB 3.0 performance by transferring data on two individual channels, resulting in faster file transfers and less wait time on data transfers. The PEXUSB3S42V 4-Port PCI Express USB 3.0 Card is enhanced with UASP support (USB Attached SCSI Protocol), allowing it to perform up to 70% faster than conventional USB 3.0 when paired with a UASP supported enclosure. This efficient protocol optimizes transfers by processing multiple commands simultaneously, significantly increasing transfer speeds.For high-power USB devices, this card includes an optional SATA or LP4 power connector to connect to your system power supply. It can deliver up to 900mA of power per port to USB 3.0 bus-powered devices (500mA for USB 2.0), ensuring your devices are adequately powered. The card also supports USB Battery Charging Specification 1.2 (Apple Mode only), enabling faster charging for compatible Apple devices. It maintains compliance with USB 3.0 standards while offering backward compatibility with existing USB 2.0 / 1.1 devices, making it a versatile addition to any setup.The USB 3.0 PCIe card comes equipped with a standard profile bracket and includes a low-profile/half-height bracket for installation in small form-factor computers. It also features a hot-swap feature, allowing you to connect/disconnect devices without powering down the system.Whether you're looking to upgrade an older PCIe-based system to USB 3.0 connectivity and UASP support, or expand the USB capabilities of your system with four external ports for connecting additional devices, the PEXUSB3S42V 4-Port PCI Express USB 3.0 Card is a durable and reliable choice.

Bought this a while back as I did a ton of research into why I was getting disconnection issues with my Oculus Rift S on my Z390 motherboard, turned out most boards don't provide enough power to the Rift S's USB connection, The fix was to buy this card, since getting it I've not had a single issue with my Rift S, it now works perfectly as it should have done, even updates that affect the USB drivers no longer causes me issues, using this card has fixed the lot. Yes its a lot to pay but its great for other peripherals too. If I had one thing I don't like about the card its the vertical slots as it sometimes makes it difficult to connect the USB into the slots as both ends of the USB impact on the PCI Brackets on my PC case, if the slots were horizontal then I've give the card 5 stars.
