A genuine Dell low-profile (LP) riser card set designed for the Dell PowerEdge R650 and R6525 1U rack servers. This kit includes the RSR2A (Riser 2A) and RSR3A (Riser 3A) riser boards, which together provide three PCIe 4.0 x16 low-profile expansion slots — the maximum LP configuration for these 1U systems.
The RSR2A riser delivers two x16 LP slots (one routed to CPU1, one to CPU2), while the RSR3A adds a third x16 LP slot routed to CPU2. This configuration is ideal for adding high-performance NICs, HBAs, RAID controllers, NVMe adapters or other PCIe 4.0 expansion cards to your 1U server.
Both risers are original Dell OEM parts (P/N 7FCYW for RSR3A and P/N M0T51 for RSR2A), ensuring proper fit, correct keying and full compatibility with supported R650 / R6525 server configurations.
Key Features
- RSR2A (Riser 2A) — 2× PCIe 4.0 x16 low-profile slots (CPU1 + CPU2)
- RSR3A (Riser 3A) — 1× PCIe 4.0 x16 low-profile slot (CPU2)
- 3× total x16 LP slots — maximum low-profile expansion for R650 / R6525
- PCIe 4.0 — up to 64 GT/s per lane, double the bandwidth of PCIe 3.0
- Low-profile / half-length — designed exclusively for 1U rack chassis
- Genuine Dell OEM — P/N 7FCYW (RSR3A) + M0T51 (RSR2A), guaranteed fit
- Ideal for NICs, HBAs, RAID controllers, NVMe adapters & other PCIe 4.0 cards

⚠ Important — Read Before Buying:
This riser set is exclusively designed for Dell PowerEdge R650 and R6525 1U rack servers. It will not fit other Dell server models (e.g. R750, R640, R740) or standard desktop / tower PCs. The slots are low-profile (LP) / half-length only — full-height or full-length PCIe cards will not fit in a 1U chassis. Verify your server model, current riser configuration (shroud type, CPU count, rear storage option) and available riser connectors before ordering. Installation may require the matching low-profile air shroud / fan configuration. We are not responsible for incompatibility caused by incorrect server model, wrong riser configuration, or use of full-height cards in a 1U chassis. Package Includes
- 1 × Dell RSR2A (Riser 2A) Low-Profile Riser Card — P/N M0T51
- 1 × Dell RSR3A (Riser 3A) Low-Profile Riser Card — P/N 7FCYW
Not included: PCIe expansion cards, air shroud, mounting screws, cables or any other server components.

FAQ
Q: Will this fit my Dell R750 / R640 / other server?
A: No. This riser set is designed exclusively for the Dell PowerEdge R650 and R6525 1U servers. It will not fit other server models due to different mechanical and electrical layouts.
Q: Can I use full-height PCIe cards with this?
A: No. These are low-profile (LP) risers for 1U chassis — only low-profile / half-length PCIe cards will fit. Full-height cards require a different riser configuration (e.g. R1a full-height) and a 2U or larger chassis.
Q: How many PCIe slots does this set provide?
A: The RSR2A provides 2× PCIe 4.0 x16 LP slots and the RSR3A provides 1× PCIe 4.0 x16 LP slot, for a total of 3× x16 low-profile slots.
Q: Does this include the air shroud or mounting hardware?
A: No. This listing includes only the two riser cards (RSR2A + RSR3A). The air shroud, screws, cables and any other server components are not included.
Q: Do I need both CPUs installed to use all slots?
A: The RSR2A has one slot routed to CPU1 and one to CPU2; the RSR3A slot is routed to CPU2. With only one CPU installed, the CPU2-routed slots will be unavailable. A dual-CPU configuration is required to use all three slots.
