PCIe Expansion Components


PCIe Expansion

is the HIGH SPEED universal serial bus


PCIe expansion is the standard for high speed connectivity from a server to a PCIe device. Vastly higher performance than USB or Ethernet,  PCIe expansion is simple, reliable, cost-effective. No software to install means no overhead and low latency. PCIe expansion has proven reliable across a multitude of applications. There are a variety of adapters to suit price-performance needs.

Below are the types of PCIe products we manufacture. For more specific information, click on a product to learn more.

PCIe is Simple, Reliable, Cost Effective with vastly higher performance than USB or Ethernet.


One Stop Systems is the industry leader in PCIe expansion products. We provide a wide variety of PCIe cable adapters, expansion kits, cables and backplanes

Cables, Kits, Cards and Backplanes

One Stop Systems was first to market with PCIe cable adapters and expansion devices. In addition, we have consistently been first with the latest technology upgrade.  We offer multiple bandwidths for PCIe cables in a wide variety of lengths. An expansion kit typically includes two cable adapters and a cable that connects a motherboard system downstream to one or more PCIe devices. All PCIe components feature the latest technology and the most reliable engineering and manufacturing.

Desktop Expansion

Choose from ExpressCard, PCIe or Thunderbolt connectivity packages. The number of slots available are 1, 2, 3, 5 or 8 and the different CUBE sizes can accommodate, full-length (13.25"), mid-length (9.5"), or short PCIe cards (7.5"). All of the various CUBEs provide ample cooling and power and they support any combination of flash drives, video, film editing, GPUs, or other PCIe I/O cards. The CUBEs are easy to install and no additional drivers or software are needed other than those required by the PCIe I/O cards.


4U Value Line Enclosure

This flexible 20-slot rackmount expansion platform provides thousands of expansion possibilities at a value price. The 4UVL supports from 1 to 8 PCIe host connections using the broadest line of PCIe 2.0 and 3.0 host interface boards and PCIe expansion backplanes in the industry. The 4UVL supports a single 20-slot backplane or any combination of backplanes from the OSS Cube product line up to a total of 20 slots. Flexible power subsystem options range from a single value-oriented 700-1200W ATX power supply to split-power or redundant power configurations.


x4 PCIe Switch

The One Stop Systems x4 PCIe Switch provides one x16 and one x4 PCIe upstream ports that fan out to 8 different x4 downstream ports, supporting PCIe devices or expansion systems.


x1 PCIe Switch

The One Stop Systems x4 PCIe Switch provides one PCIe x1 upstream port fans out to seven different x1 downstream ports supporting PCIe devices or expansion systems.

Riser Cards

NVMe Adapter Card and PCIe Riser Card

One Stop Systems offers two special cards specifically designed to make testing a high volume of other cards quick and easy. The first card is the NVMe Solid State Drive (SSD) Adapter card. This card can be very useful for testing NVMe SSDs. The second card is a PCIe riser card, which can be used for testing any PCIe card. When used in the OSS Flash Storage Array Test System (FSA-TS), these two cards can test up to 32 NVMe SSD or PCIe cards at once. To learn more about the FSA-TS, click here. To download the datasheets for either of these two cards, click the buttons below.
