  • TypeController Card
  • Supports PCIe 4.0 x4 for fast NVMe SSD performance
  • Fits EDSFF E1.S 110mm drives with included fixing screws
  • Works in PCIe x4, x8 or x16 slots on Gen 3/4 motherboards
  • Includes high-profile and low-profile brackets for any chassis
  • Backwards compatible with PCIe Gen 2 and Gen 1 systems

EDSFF E1.S 110mm adapter

This PCIe 4.0 x4 expansion card mounts a single EDSFF E1.S 110mm NVMe drive into a standard slot. It targets builders adding enterprise-form-factor storage to workstations or servers without native EDSFF bays. The board ships with both high-profile and low-profile brackets for flexible chassis fit.

Sustained thermal behaviour

The adapter is a passive controller with no active cooling of its own. Drive temperatures under continuous load will depend entirely on case airflow and the SSD's own thermal design. No throttling data or thermal limits are provided by the manufacturer.

PCIe 4.0 x4 interface limits

The card operates at PCIe 4.0 x4 and is backward compatible with Gen 3, Gen 2 and Gen 1 slots. Maximum throughput is capped by the host slot generation and the installed drive's rated speeds. Boot support requires a motherboard with NVMe boot capability.

Questions about this item

Does the LRNV9EN4 generate noticeable noise or heat when running all day?

The card is a passive PCIe 4.0 x4 controller with no fan, so it produces no audible noise and relies on case airflow for cooling.

What must I already own for this adapter to work?

You need a motherboard with a PCIe x4, x8 or x16 slot and an EDSFF E1.S 110mm NVMe SSD to install in the adapter.

Will this card work alongside my older PCIe Gen2 motherboard?

The adapter is backward compatible with PCIe Gen2 and Gen1 slots, though maximum throughput is limited to the older bus speed.
