Interface Card Supermicro RSC-R1UW-E8R

The Supermicro RSC-R1UW-E8R is an internal riser/interface card for 1U servers that converts a WIO slot into a single PCI‑Express x8 I/O port. Designed for compact rack servers, this passive riser enables installation of a standard PCIe x8 add-on card in systems with limited internal expansion space.

Advantages

The riser card provides a reliable passive connection from a WIO slot to a PCIe x8 interface without requiring external power. Its compact 1U form-factor compatibility helps maintain low-profile server builds while offering a direct PCIe lane connection for high-speed peripherals. As an internal component, it is suitable for integration into existing Supermicro 1U chassis that support the matching WIO connector.

Suitable for

• Adding a single PCI‑E x8 expansion card in 1U rack servers
• Upgrading network, storage controller, or accelerator cards where a PCIe x8 interface is required
• Systems with a WIO slot that need a standard PCIe connection

How to use

Power down the server, open the chassis and locate the WIO connector on the motherboard or backplane. Insert the RSC-R1UW-E8R riser into the WIO slot until fully seated and secure it according to chassis mounting points. Install the PCIe x8 add-on card into the riser’s PCIe slot, fasten the card bracket, close the chassis and power on the system. Verify that the server BIOS/firmware recognizes the added PCIe device and install necessary drivers in the operating system.

Usage recommendations

Ensure compatibility with your 1U chassis and motherboard WIO connector before installation. Handle the card with ESD precautions and confirm that the chosen PCIe card’s height and connector type match the riser’s x8 slot and the server’s clearance limitations.
