PCIe Gen4 to SlimSAS 16i adapter
This adapter converts a PCIe x16 Gen4 slot into a SlimSAS 16i (SFF-8654) interface for the RTX 3080. It targets builders who need to relocate the GPU using high-speed cabling. The integrated ReDriver maintains signal integrity across the 16 differential lanes. Buyers who want a simple bracket or internal riser will not use this product.
Bifurcation support and clock buffering
The 16 lanes can be bifurcated into four x4 or two x8 link widths for different topologies. A built-in PCIe 4.0 100MHz clock fanout buffer drives two x4 outputs to support longer cables. An SMBus switch and I/O expander handle out-of-band management and remote reset signals. Systems that require a fixed x16 link without bifurcation will not benefit from this flexibility.
Power delivery and signal conditioning
Onboard 12V to 3.3V conversion supplies up to 5.5A through a PWM controller and load switch. Dedicated buffers for PERST#, WAKE#, CLKREQ# and PWRBRK# preserve sideband signalling over extended cable runs. The ReDriver extends 16GT/s differential pairs to maintain link stability. Builds that stay within standard slot length will not need this level of signal conditioning.

Questions about this item
Will this adapter work with the PCIe 3.0 slot on my older motherboard when paired with an RTX 3080?
The adapter uses PCIe Gen4 signalling at 16 GT/s with a built-in ReDriver; it will negotiate down to Gen3 speeds in a 3.0 slot while keeping all 16 lanes active.
How can I verify the SMBus switch and I/O expander are communicating after installation?
The SMBus switch at address 0x70 and I/O expander at address 0x20 appear on the system management bus; they can be probed with standard I2C tools to confirm OOB management and reset functions.
Does the box include the 12 V power cable needed for the onboard 3.3 V, 5.5 A PWM controller, or must I source it separately?
The adapter integrates a 12 V to 3.3 V, 5.5 A PWM power controller and load switch, drawing auxiliary power through the PCIe slot; no external power cable is required.
