PCIe 3.0 4.0 U.2 NVMe Adapter Kit
This adapter connects a U.2 NVMe SSD to a motherboard via a PCIe slot using the included 50 cm cable. The kit contains one card and one cable for direct NVMe storage attachment. It is intended for builders adding enterprise or high-capacity U.2 drives to a desktop platform. It does not support SAS or SATA devices.
Sustained PCIe 3.0 4.0 Link Performance
The adapter maintains a 4x PCIe 3.0 or 4.0 connection to the drive under continuous workloads. Bandwidth scales with the host slot generation and the SSD capabilities. No active components on the card alter signal quality during extended transfers. Thermal throttling depends on the drive and system airflow, not the adapter itself.
Passive Thermals and Power Delivery
The card draws no auxiliary power and adds negligible heat to the chassis. The cable routes power and data from the slot to the U.2 drive without active cooling. Noise is limited to the system fans already present. Power delivery follows the PCIe slot specification for the attached NVMe device.

Questions about this item
Does the adapter card generate noticeable heat or draw extra power when a U.2 NVMe SSD runs continuously?
The adapter is a passive PCIe 3.0 4.0 card with no active components, so it adds no measurable heat or power draw beyond the SSD itself.
What motherboard slot and drive interface are required to use this kit?
You need a free PCIe x4 slot (3.0 or 4.0) on the motherboard and a U.2 SFF-8639 NVMe SSD; the 50cm cable connects the card's SFF-8643 port to the drive.
Will this work with an older SATA or SAS drive I already own?
No — the kit is designed only for NVMe U.2 SSDs such as the 750 series and explicitly does not support SATA or SAS disks.
