Add 2 high-speed RS-232 serial ports to your low profile/small form factor computer with a PCI Express expansion slot

The PEX2S553LP low profile/half-height PCI Express Serial Card turns a PCI Express slot into two RS232 (DB9) serial connections.

The card is constructed using a native single chip design that lets you harness the full capability offered by PCI Express (PCIe), while reducing the load applied to the CPU by as much as 48% over conventional bridge chip serial cards.

The PCI Express RS232 Serial Adapter Card is compatible with a broad range of operating systems, including Windows®; and Linux Kernel 2.6.11 to 4.11.x, and ships with a low profile/half-height bracket installed but includes an optional full profile bracket that lets you add 2 serial ports to virtually any computer (regardless of the case form factor).

This product is a replacement for our PEX2S552LP card.

The StarTech.com Advantage
USB Interface with DM-D
Add 2 native FireWire 800 ports to your computer through a PCI Express expansion slot

This 3 Port PCI Express FireWire adapter card can be installed in a PCI Express slot to add two IEEE1394b (FireWire 800 - 9 pin) ports and one IEEE1394a (FireWire 400 - 6 pin) port, providing broad compatibility with a wide range of FireWire devices (e.g. DV camcorders, external hard drives, digital cameras, etc.).

The 2b, 1a card features a native (single chip) PCI Express chipset - resulting in faster, more reliable and cost effective performance than expansion cards that utilize a "bridge" chip.

The StarTech.com Advantage
Add RS232, RS422 and RS485 support to your laptop or desktop computer via USB

The ICUSB2324852 2 Port USB to RS232 RS422 RS485 Serial Adapter with COM Retention lets you connect every type of serial device to your USB-enabled computer, whether it be for RS232, RS422, or RS485 communication.

The StarTech.com Advantage
Add 4 SuperSpeed USB 3.0 ports to a computer through a PCI slot

The PCIUSB3S4 4-Port PCI to USB 3.0 Card enables legacy PCI slots to support the SuperSpeed USB 3.0 standard, which is capable of data transfer rates up to 5 Gbps. Using USB 3.0 devices with this card will increase data transfer rates with up to 1.3 Gbps of available bandwidth (PCI bus limit) - more than doubling performance compared to a USB 2.0 connection.

This versatile USB 3.0 adapter includes an optional SATA power connector which allows each USB port to deliver up to 900mA of power to connected USB 3.0 devices - suitable for even the most power hungry devices.

A perfect solution for older PCI-based systems or computers with only PCI expansion slots remaining, the card allows those systems to stay relevant and up-to-date with the latest USB technology. The card is also backward compatible with USB 2.0 and 1.x devices, so it will not only work with any future USB 3.0 devices, but will also support older devices.

The PCIUSB3S4 4-Port PCI USB 3.0 Card is backed by StarTech.com lifetime warranty and free lifetime technical support.

The StarTech.com Advantage

- Increased data transfer rates (up to 1.3 Gbps PCI bus limit) with USB 3.0 compatible devices
- Suitable for installation in standard-sized and Small Form Factor computers
- Supports bus-powered USB 3.0 devices
