𝐃𝐢𝐋𝐢𝐧𝐤𝐞𝐫 𝐌.𝟐 𝐭𝐨 𝐔.𝟐 𝐍𝐕𝐌𝐞 SSD, 𝐒𝐅𝐅-𝟖𝟔𝟑𝟗 Drive to 𝐌.𝟐 Host Adapter,U.2 SSD Converter -with Power Cable(50CM)

I've only been using this cable for a few hours, but this has been the ONLY cable on the market that so far appears to properly work with chipset-driven M.2 slots, at least on this MSI board running an Intel CPU.I had two spare M.2 slots in my NAS I was hoping to use a simple M.2 to SFF adapter with, but that did not work on my chipset-drive M.2 slots. This cable worked.The length of the cable is a bit small, likely due to PCIe signal limitations, but it's the perfect length for my 3U NAS.So far, so good, if it ends up being bad or causing issues with my P4800x's, I'll update my review.

Same length and build as the intel one that came in my other (retail) optane drive. Works the same. No issues. I know it's a very niche product, but a few more inches on the cable length would have been better. Then, again, the nvme connectors on most motherboards are placed in spots where they're covered by add-in cards. Just be aware of that.

Works great for my Optane SSD!

Connected it and does not even show in bios. Don’t recommend.

Worked great to plug in my Intel P4510, freeing up a PCIe slot. Note that it doesn’t include the standoff screws- you’ll need those from your motherboard or case.

Functionality: absolutely works, zero issues there. If you have any U.2 drives and don't want or can't use a traditional PCIe slot then this is a solid choice. There are some quirks, continue reading.Will it fit under my motherboard SSD heatsink?: Your mileage may vary. Others have said it won't fit and that's more likely than not. In my case, I could, once I moved the cable wrap further down the wires, flattened them out, and removed any thermal pads underneath the heat spreader (see attached images).Quirks: make sure there are no tight bend radii throughout the cable's length for best performance. I used this connector for an Optane (RIP) drive and my 4KQ1 performance was 2/3rds the normal performance before I rerouted the cables to change the way they were arranged in my case. After that, everything was fine.Misc: these apparently use Amphenol connectors (legitimacy unknown) and this looks very similar to the Intel branded m.2 to u.2 adapter they would bundle for their drives. PCIe gen 4 speeds may not be fully reachable with this adapter (untested on my end)

Picked one of these up to add a U.2 drive to my X570 AMD system. Unfortunately the Taichi heat spreader plate did not allow this thick of a cable underneath the m.2 builtin heat spreader. This spreader was one piece for all m.2 devices, and since I have 2 other devices in the system, there was no way to skip using it.If the cable management was FLAT instead of round, it would have worked. Alas, I found a 25% cheaper PCIE 3.0 x4 card that enabled u.2 drives after I discovered this, and thus returned the cable.Given my experience here, I'd recommend the pcie card before the m.2 to u.2 converter. Just makes more sense!

Worked great on my older AMD board to connect an Optane drive as my new OS drive. The drive is only pcie 3 so I dont know how well this cable works on pcie 4 devices but that doesnt matter much to me right now as the 5800X Optane series is VERY expensive and will be for years to come. For now, it performs flawlessly on a storage stress test for my PCIE 3.0 905p Optane drive.
