SlimSAS 4i and U.2 Adapter
The Innocard GD0804A provides a PCIe Gen4 connection between a SlimSAS 4i port or a U.2 SFF-8639 device and a PCIe x4 slot. It suits builders adding enterprise storage or accelerator cards to a workstation or server platform.
Upgrade from Gen3 or direct-attach limits
Replaces a Gen3 riser or a single-port bracket when 16 GT/s bandwidth and dual PCIe x4 slots are needed. The jump is worth it when the workload saturates a Gen3 link or when hot-plug power management is required.
Installation and common issues
The card seats in a standard PCIe x4 slot and exposes two x4 connectors with SFF-9402 Rev1.1 pin-outs. Problems usually arise if the backplane type detection for Broadcom 95xx Tri-Mode adapters is not configured or if the 6.5 A current limit trips under heavy load.

Questions about this item
What physical slot does the Innocard GD0804A need on the motherboard?
The adapter fits a standard PCIe x4 slot and occupies a single expansion bracket space.
What is the installation step people often miss when fitting this adapter?
Connect the motherboard 12 V power cable to the on-board eFuse header before seating the card; the 6.5 A current limit and inrush slew-rate control only activate when that feed is live.
Which replaceable component protects the 12 V rail if a drive draws too much current?
The programmable eFuse trips at 6.5 A and can be reset after the fault is cleared, avoiding a full board swap.
