New flat M.2 SSD adapter doesn't stick out from the motherboard, unlocking PCIe slots hidden under massive GPUs — JEYI's new 'ArcherX' AIC lays completely flush and supports PCIe 4.0 speeds

Adding more storage to your PC can prove to be a difficult task if your GPU is covering the M.2 slots. And if they're already filled, adding an expansion card to an empty PCIe slot can be a bit tricky because your GPU could block that, too. JEYI, a popular accessories manufacturer from China, has a solution to this problem: a flat PCIe-to-M.2 adapter that sits completely flush with the motherboard.

Most AIC (add-in cards) take up perpendicular space inside the chassis because they stick out vertically from the motherboard. Modern graphics cards are often so large that they block even neighboring PCIe slots, making it impossible to add the adapter even if there's space otherwise. JEYI's flat adapter solves this by putting the M.2 slot parallel to the board, similar to an actual, native M.2 slot, so it doesn't protrude at all.

The adapter is called "ArcherX" and comes in two flavors: PCIe 4.0 x1 and PCIe 4.0 x4. Both are also backward compatible with PCIe 3.0, and the vendor teased a PCIe 5.0 adapter in the works as well. The card is made by soldering two PCBs together — on one side, you have the PCIe connector itself and, on the other, you have the M.2 slot. It has a long, thin bar sticking out with a screw mount at the end for full-size (2280) SSDs. Contrary to how it may look, the company says it's very rigid.

JEYI chose to keep the adapter as small as possible to ensure no surrounding componentry comes in the way. There's no price or availability yet, but considering PCIe to M.2 adapters are cheap, and JEYI produces budget-oriented accessories, we should see this drop around the $20-30 mark. If you want to see another useful PCIe adapter like this one, check out this platypus adapter that adds two M.2 slots.

    That's pretty dang cool! And the one thing I love about PC modding - there's pretty much a solution to every scenario.

    My only concern is the adapter sliding out just enough that the SSD comes in contact with the GPU heatsink.

    Its a good design. Some years back though a few motherboards that had m.2 slots vertical hit the market but it never took off in popularity. I can see the fragility question with vertical for sure but it does use space better where traditional placement is really wasteful.

    Traditionally flat placement can be a wash in a lot of areas, but on the real estate of a motherboard where typically PCIe slots would be placed, m.2 slots are the most wasteful of all in removing PCIe slots in their place by the manufacturer.

    Nice solution. I have a perfectly good PC with ample memory and graphics but reading about motherboard slots gets me thinking about that NEXT computer... So fun. :)

    My motherboard has spots for 5 m.2 drives all over. I know it's made for it but there are 3 that are under the gpu. I haven't had any issues with them thermal throttling.

    I doubt that will happen. How often do you move your desktop around harshly enough to make a pcie card pop out? Those pins usually have a pretty good grasp. At the same time, they should have made it long enough to actually latch in like a gpu does. Then there would be no chance.

    I bought a JEYI SSD heatsink, a few years ago. It was the only 110 mm heatsink I could find that provided full coverage of both sides. I had one of those (now rare) 22110 SSDs that had NAND chips on both sides!

    I did really appreciate find at least one option out there, that was exactly what I wanted. It wasn't the most amazing SSD heatsink, but it worked more than well enough for my needs.

    It seems to me that it's hard for non-Chinese manufacturers to go after these niche markets where you can't necessarily charge a high premium.

    You could fold a small bit of paper and wedge it in between, as a makeshift spacer.

    However, I don't really see what mechanism of action would cause the adapter to work loose.

    Fair, but not all graphics cards exhaust downwards towards the motherboard. At least, I think blower-style cards don't.

    Vertical M.2 slots wouldn't really provide much benefit over just using a PCIe add-in-card adapter, other than the fact that most motherboards don't necessarily give you an option to route to either M.2 or AIC slot for all of those lanes.

    The main "benefit" of M.2 slots is the ability to use space under the second slot of a 2+ slot GPU. The obvious problem with that is cooling...
