LORDWORLD PCI-E 4x to 16x Riser Card 15cm 4-pin

SKU CH-Q79Q-SMRBC

A 15 cm flexible riser extends a PCIe 4x slot to a 16x connector with a 4-pin power feed for low-profile chassis

  • Extends a PCIe 4x slot to accept 16x cards
  • 4-pin power connector on the riser board supplies stable auxiliary power
  • 15 cm high-speed FFC ribbon allows flexible routing inside 1U to 3U chassis
  • Single 4x riser slot supports 4x, 8x and 16x cards at 4x electrical speed
  • Compact adapter converts a 4x interface into a full-length 16x mechanical slot

PCI-E 4x to 16x riser card

This riser card adapts a PCI Express 4x slot to accept cards with a 16x edge connector. It uses a 15 cm flexible FFC cable so the card can be mounted horizontally in 1U, 2U or 3U chassis. A four-pin power connection on the PCB supplies the card with auxiliary power. The adapter is aimed at system integrators who need to fit full-length expansion cards into low-profile servers or industrial enclosures.

Suits low-profile chassis builds

The design fits 1U, 2U and 3U cases where a standard vertical slot cannot be used. It supports cards with 4x, 8x or 16x connectors, although the electrical link remains limited to 4x bandwidth. Builders who need full 8x or 16x throughput should not use this adapter. It is also unsuitable for systems that lack a free 4x slot or a four-pin power header.

Link limited to 4x speed

The single specification that decides compatibility is the electrical width: the riser provides only a PCIe 4x connection regardless of the card's physical connector. Any card requiring more than 4x lanes will operate at reduced bandwidth. Check that the host platform can allocate a 4x link and that the card functions correctly at that width before purchase.

Questions about this item

Do I need a motherboard with a free PCI-E x4 slot to use this riser?

Yes, the riser plugs into an open PCI-E x4 slot on the motherboard to extend a graphics or add-in card.

Will my PCI-E x16 graphics card run at full speed when connected through this adapter?

The card will operate at x4 electrical speed because the riser only provides four lanes, even though the physical slot is x16.

How can I confirm the riser is delivering power to the card after installation?

The 4-pin power connector on the riser board should be attached to a PSU cable; the card's fans spinning and detection in BIOS confirm operation.
