Innocard GD0804A PCIe Gen4 SlimSAS 4i U.2 Adapter

SKU CH-02GV-EBX1Z

Connects a U.2 drive and a SlimSAS 4i cable to two PCIe x4 slots with Gen4 16GT/s bandwidth and built-in 12 V hot-plug power protection

  • Changer TypePCIe Gen4
  • PCIe Gen 4 16GT/s bandwidth for high-speed storage
  • Dual conversion: U.2 and SlimSAS 4i to PCIe x4 slots
  • Broadcom 95xx Tri-Mode RAID and HBA compatibility
  • Hot-plug +12 V power with 6.5 A eFuse protection
  • SFF-9402 Rev 1.1 pin-out compliance for reliable connections

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.
