PCIe & GPU ENABLEMENT
Dell PowerEdge PCIe Risers, GPU Enablement Kits & NVLink Bridges
Genuine Dell expansion-card risers, GPU full-length conversion kits and NVLink bridges matched to chassis and riser configuration, so new PCIe cards and accelerators seat correctly and stay within Dell airflow and power rules.
Risers define which PCIe cards a chassis can accept, and they are model and configuration specific. We supply the genuine Dell riser or GPU enablement kit for your server, confirm the supported riser configuration against the service tag, and include the shroud and power parts where a conversion requires them.
Risers and enablement we supply
Standard expansion risers
Model-specific riser cards that provide full-height and low-profile PCIe slots for network, storage and host-bus adapters.
Full-length GPU risers
Risers that add full-length, double-width slots required to fit larger GPU accelerators in the chassis.
GPU enablement kits
Conversion kits that bundle the risers, GPU shroud, L-type heatsinks and power cables needed to move to a validated GPU configuration.
Left and right GPU risers
The paired RF1/RF2 left and right GPU risers used in multi-accelerator platforms such as R760xa.
NVLink bridges
Bridges that connect paired NVIDIA A100 or H100 GPUs for high-speed peer-to-peer communication.
Riser upgrades
Config-to-config riser upgrades, including added low-profile slots, confirmed for the specific chassis.
Common applications
- Adding PCIe network or storage adapters that need a new riser
- Converting a server to a full-length double-wide GPU configuration
- Connecting paired A100 or H100 GPUs with an NVLink bridge
- Replacing a damaged riser or restoring a supported riser config

What to specify when ordering
- Server model, service tag and current riser configuration
- Card or GPU to be fitted (height, length, width, power)
- Whether a full GPU conversion kit is required
- If GPUs are paired, whether an NVLink bridge is needed
Frequently asked questions
What does a PowerEdge riser configuration determine?
The riser configuration defines how many PCIe slots the server has and their height, length, width and signalling. It must support the specific card or GPU you want to fit.
Are risers interchangeable between PowerEdge models?
No. Risers are chassis and configuration specific, so a riser from one model or generation generally does not fit another. We confirm the exact part against the service tag.
What is included in a Dell GPU enablement kit?
A full-length GPU kit typically bundles the required risers, a GPU shroud, L-type heatsinks and GPU power cables so the chassis moves to a validated GPU configuration.
Can I fit a double-wide GPU in any riser configuration?
No. Double-wide GPUs are only supported on specific riser configurations; unsupported or APOS configurations are not valid. We confirm the supported config before you order.
What are left and right GPU risers?
On multi-GPU platforms such as R760xa, paired RF1 (right) and RF2 (left) GPU risers hold the front accelerators and must be used in the validated combination.
What is an NVLink bridge and when do I need one?
An NVLink bridge connects two paired NVIDIA GPUs for high-speed peer-to-peer traffic. It is used for paired A100 or H100 cards where the workload benefits from direct GPU-to-GPU links.
Do I need new heatsinks when converting to GPUs?
Often yes. GPU kits include the required L-type or high-performance heatsinks and shroud because adding accelerators changes the airflow and thermal profile of the chassis.
Can I upgrade from one riser configuration to another?
Some config-to-config upgrades are supported, including adding a low-profile slot or moving to a full-length GPU config. We confirm the supported path and supply the needed parts.
Why is the new PCIe card not recognised?
Common causes are fitting the card to an unsupported riser configuration, a mismatched riser, or a power or airflow restriction. We verify the riser and kit against the server.
Are these new genuine Dell parts?
Yes. We supply new genuine Dell risers and GPU enablement parts validated for the chassis, rather than untested brackets that can break airflow or void support.
Can I buy a single riser instead of the full GPU kit?
Yes. If you only need one riser and already have the shroud and power parts, you can order the individual validated riser for your configuration.
Does the riser generation affect PCIe speed?
Yes. Risers and platforms range from PCIe Gen3 to Gen5. The card negotiates at the speed the riser and platform support, which we confirm for the intended device.
Do AMD EPYC servers use different risers?
AMD-based PowerEdge chassis can use their own riser revisions and supported configurations. We confirm the correct riser for the specific AMD model and service tag.
How are risers and GPU kits shipped?
Risers and bridge cards are packed to protect the connectors and boards; full GPU kits can be consolidated and shipped with the accelerators or a server order.
