ipolex PCIe 4.0 x16 to Quad U.2 NVMe Adapter Card, 4-Port SFF-8639 for 2.5" U.2 SSD, with 4-Pin Power, Supports BIOS Boot, Requires PCIe Bifurcation

Key features

• Requires motherboard PCIe x16 slot support for x4+x4+x4+x4 bifurcation to recognize all four drives. If your motherboard supports x8+x4+x4, only three drives will be detected; x8+x8 bifurcation will limit recognition to two drives. Please verify your motherboard's BIOS capabilities before purchase.
• When operating four U.2 NVMe SSDs simultaneously, the PCIe slot's standard 75W power delivery may be insufficient. For stable operation, connect the included 4-pin auxiliary power cable from the adapter card to your chassis power supply – ensuring reliable performance under full load.
• Configure the adapter as a bootable system disk by enabling PCIe boot in your motherboard BIOS – ideal for building high-performance workstations or servers with U.2 NVMe SSDs as the primary drive.
• Designed specifically for 2.5" U.2 NVMe SSDs. Please note: SAS/SATA drives are not supported, and hot-swapping is not supported – power off system before installing or removing drives.
• Includes a full-height bracket with a sturdy back-reinforcement design that enhances structural stability and improves heat dissipation – ensuring reliable operation even under sustained high workloads.
