U.2 to PCI-E 3.0 x4 Adapter

This adapter converts a 2.5-inch U.2 NVMe SSD or SATA SSD to a PCI-E 3.0 x4 slot. It fits Intel 750 series and DC P3500, P3600, P3700 drives. The board uses a direct copper conductor path without extra chips. Builders adding enterprise U.2 storage to a desktop platform will find it useful.

Upgrade from M.2 or SATA-only boards

The card adds a U.2 SFF-8639 port and a SATA 7-pin connector to systems lacking native support. It draws drive power from the PCI-E slot so no separate power cable is needed. The jump is worth it when the motherboard has a free x4, x8 or x16 slot but no U.2 header. Buyers whose board cannot boot NVMe should note the drive will work only as secondary storage.

Sustained throughput at PCI-E 3.0 limits

PCI-E 3.0 x4 tops out at 32 Gbit/s while SATA 3.0 reaches 6 Gbit/s. Actual speed stays at the attached drive’s rated value because the adapter adds no controller overhead. The passive design means thermal behaviour matches the slot airflow and the SSD’s own throttle point. No active cooling is included so sustained loads rely on case ventilation.

Questions about this item

Does this U.2 SFF-8639 adapter require a PCIe x4 slot or will it fit in x8 and x16 slots?

It installs in any PCIe x4, x8 or x16 slot on the motherboard. The card uses a PCI-E 3.0 x4 electrical interface, so it works in wider slots as well.

Which cables and screws are needed to mount a 2.5" SATA SSD on this card?

Use the included SATA 7-pin data cable and the four M3 screws with the provided screwdriver. The SATA drive also needs its own 15-pin power cable from the PSU.

If I later swap the U.2 NVMe drive for a SATA SSD, what extra connection is required?

A SATA 7-pin data cable must be attached to the card's SATA port; the U.2 drive works without a data cable, but the SATA drive does not.
