❓ Frequently Asked Questions (FAQs)
Q1: Is this adapter compatible with my Windows system?
A: Yes, the IO-PEX86123 supports Windows 7, 8, 8.1, 10, 11, and later versions. Your system must have UEFI 2.3.1 or later for optimal compatibility. Most modern systems meet this requirement.
Q2: How do I install the Lekuo PCIe to OCuLink adapter?
A: Installation is straightforward - power off your system, insert the adapter into an available PCIe x4 or higher slot (x8, x16 slots also work), secure with the included bracket, connect your OCuLink NVMe SSD, and power on. The system should automatically detect the device.
Q3: Do I need special drivers for this adapter?
A: For most modern Windows systems (Windows 10/11 with UEFI 2.3.1+), the adapter works plug-and-play without additional drivers. For Windows 7/8/8.1 or specific configurations, drivers are available for download from our support page.
Q4: What is the difference between PCIe Gen3 and Gen4 support?
A: This adapter supports both PCIe Gen3 and Gen4 x4 interfaces. Gen4 offers double the bandwidth of Gen3 (up to 64 Gbps vs 32 Gbps). The adapter automatically negotiates the best speed based on your motherboard and SSD capabilities, ensuring backward compatibility.
Q5: What type of SSDs can I connect with this adapter?
A: This adapter is designed for external NVMe SSDs with OCuLink (SFF-8612) connectors. It supports SSD form factor 1a and is fully NVMe 1.2a compliant, ensuring compatibility with high-performance NVMe storage devices.
