Supermicro RSC-R2UW-4E8 PCIe x16 4-slot riser card

SKU CH-P45V-M311P MPN RSC-R2UW-4E8

Adds four PCI Express 3.0 x8 slots from a single x16 link in a 2U riser for compatible Supermicro chassis

  • Four PCIe 3.0 x8 slots from one x16 link
  • Fits 2U rack height for dense server builds
  • Supports SuperChassis SC815TQ-600WB and SC113TQ-600WB
  • Works with mid-tower SC732D and i-865B cases
  • Adds expansion capacity without extra host connections

PCIe x16 host with four x8 slots

This riser card presents a single PCI Express x16 host interface and splits it into four PCI Express 3.0 x8 expansion slots. It is designed for Supermicro 2U rackmount and mid-tower chassis that need additional add-in card capacity in a compact form factor.

Four x8 lanes from one x16 link

Under sustained load each slot operates at PCI Express 3.0 x8 electrical bandwidth because the x16 upstream connection is divided equally among the four connectors. The card contains no active switching or PLX bridge, so total throughput is limited to the host link capacity.

Verify chassis and slot clearance

Confirm that your Supermicro chassis is one of the listed models: SC815TQ-600WB, SC113TQ-600WB, SC732D or i-865B. Ensure the motherboard provides a full-length PCI Express x16 slot and that the 2U riser bracket aligns with the chassis mounting points before ordering.

Questions about this item

How much power does the PCI Express x16 host interface draw when the riser card runs continuously?

The riser card itself is passive and draws no measurable power; only the four PCI Express 3.0 x8 add-in cards you install will consume power from the system supply.

Which chassis must I already own for this riser card to fit and function?

It is designed for Supermicro SuperChassis SC815TQ-600WB or SC113TQ-600WB, and for Supermicro mid-tower chassis SC732D or i-865B.

Will the PCI Express 3.0 x8 slots work with older PCI Express 2.0 cards I want to keep?

Yes, each slot is backward compatible so PCI Express 2.0 cards will operate at their native speed when installed.
