Delock PCI Express x4 κάρτα σε 4 x USB 5 Gbps USB Type-A τετρακάναλη

In a busy engineering lab, a technician needs to transfer large datasets from multiple high-speed USB devices simultaneously. The Delock 91846 expansion card installs into a PCIe x4 slot and provides four independent USB 5 Gbps Type-A ports, each with its own controller, ensuring full bandwidth for every connected device without bottlenecks.

Key specifications

• Host interface: PCI Express x4 (PCIe 3.0)
• Output interface: USB 3.2 Gen 1 (5 Gbps) Type-A female, 4 ports
• Chipset: 4 x ASMedia ASM1042A (one per port)
• Data transfer rate: up to 5 Gbps per port
• Backward compatible with USB 2.0/1.1 and PCIe 2.0/1.0
• Power connector: 1 x SATA 15-pin power female
• Supports UASP and xHCI specification 1.0
• Bootable, low-profile bracket included
• OS support: Windows 8.1/10/11, Linux Kernel 4.x.x and above

Why choose it

Unlike standard USB cards that share bandwidth among ports, this quad-channel design dedicates a separate controller to each port, guaranteeing consistent 5 Gbps performance even when all four ports are in use. The included low-profile bracket makes it compatible with slim desktop cases, and the SATA power connector ensures stable operation for power-hungry devices.

Ideal use cases

• Connecting multiple external SSDs or hard drives for fast backups
• Adding high-speed USB ports to a workstation or server
• Using multiple USB cameras or data acquisition devices simultaneously
• Upgrading older systems to USB 3.2 Gen 1 speeds

Good to know

The card requires a free PCIe x4, x8, or x16 slot and a SATA power connector from the power supply. It is plug-and-play with modern operating systems; drivers are included for Windows, while Linux kernels 4.x and newer have native support. The card is bootable, allowing you to boot from a connected USB drive if your motherboard supports it.
