Review on 🔌 StarTech.com U.2 to PCIe Adapter - x4 PCIe - For 2.5" U.2 NVMe SSD - SFF-8639 PCIe Adapter - U.2 SSD - PCIe SSD - U.2 Drive (PEX4SFF8639) - Enhanced SEO by William Mistretta

. This allowed me to connect my U.2 Samsung PM953 1.9TB to my machine (EVGA z370 Micro) and fixed a strange issue I had with the previous setup (M.2 to U.2 adapter powered by intel). With the M.2 to U.2 adapter I had, the system would power back on a few seconds after each OS-initiated shutdown. /suspend. Switching to this connection method fixed that .U.2 NVME drives are still quite rare and non-HEDT/server boards typically lack the appropriate connectors. If you have a free x4 slot and a U.2 SSD you want to plug in, try one of those first.
