PCIe Gen4 x4 Adapter with ReDriver
This adapter converts a single PCIe 4.0 x4 slot to either an M.2 NVMe SSD or an EDSFF 1C SSD. It includes a ReDriver that boosts signal integrity up to 17 dB at 16 GT/s, plus a 100 MHz clock buffer for extended trace lengths. On-board SMBus devices at addresses 0x21, 0x6C and 0x71 provide IPMI control and reset functions. Power enable and PERST# buffering support out-of-band management.
Suits servers needing flexible EDSFF
Builders who require a fixed M.2 slot without EDSFF capability should consider a simpler riser. Systems lacking SMBus management infrastructure cannot use the remote reset and power-control features. The card occupies one PCIe x4 slot, so platforms without a free x4 lane cannot accommodate it. Buyers needing dual-drive support must use two separate adapters.
PCIe 4.0 x4 ReDriver extends signal reach
The integrated ReDriver applies up to 17 dB gain on 16 GT/s differential pairs, while the 100 MHz clock buffer drives longer cables. SMBus addresses 0x6C and 0x71 enable BMC control of PERST#, WAKE# and CLKREQ# buffers. Independent 12 V and 3.3 V enable pins manage EDSFF and M.2 power domains. This signal conditioning decides whether the adapter works in your chassis.

Questions about this item
How can I confirm the adapter is passing PCIe Gen4 signals correctly after installation?
The on-board ReDriver boosts 16 GT/s differential pairs by up to 17 dB and the PERST#, WAKE# and CLKREQ# buffer gates remain active over extended traces, so link training at Gen4 x4 confirms correct operation.
What connectors and accessories are included versus what must be sourced separately?
The card provides a built-in EDSFF 1C latch connector and an M.2 M-key slot; you choose one drive to install. No drive, mounting screws or external cables are supplied.
Which version should I select for an EDSFF 1C drive versus an M.2 NVMe drive?
This single adapter supports both form factors — use the EDSFF 1C latch for 1C SSDs or the M.2 M-key socket for M.2 NVMe SSDs; only one drive fits at a time.
