GELRHONR NGFF M.2 to PCI-E 4X 1X Riser Card,M.2 Key M 2260 2280 SSD Port to PCIE Adapter with LED Indicator SATA 15pin Power Riser for Bitcoin Miner Mining-Black

Provides a stable PCIe 4.0 x4 connection to an RTX 3070, which I'm using as a secondary GPU for Blender. Connection remains stable after 10 minutes of rendering. Installation was no different than installing any M.2 SSD—extremely easy—and it worked with no troubleshooting. The included screwdriver wasn't super useful to me, but it's cute. SATA power adapter is extremely stiff and difficult to connect to PSU cable, but works as it should. Make sure your motherboard chipset's heatsink isn't in the way! x16 devices are too long to clear most modern chipset heatsinks. Devices should still work if the heatsink is low-profile, but I recommend an alternative means to secure x16 devices. Unless your motherboard has an interesting layout, you cannot use your case's expansion mounting brackets.

Ordered three, one did not work. I was testing a Mellanox Connectx-4 LX PCIE card in the NVME slot of multiple different AMD motherboards. Has a bright green LED which I don't like. On the one unit that failed the green power indicator light was still on.

Connected a 750 ti (60 watts), an m.2 to usb 4 enclosure plus a 120w 12v brick. Cheap way to add an egpu to a compatible pc.

Works out of the box

Rating accounts for the price of this item being $10. Pro's, it works, I used it will a pcie 4.0 x4 extension cable and tested it with a SAS card. It worked right off the bat no issues. This would suggest to me that this would work fine with a 10gb nic as well as the SAS cards are a little power hungry. Cons. the PCB is very thin, and the way it is setup I don't that it is likely to line up with your case card slots. Given that the PCI slot is at the top/upper portion in my case the slot interferes with my GPU (even when I use the riser cable) - plan accordingly for your own circumstances. If you are going to use this with a either a rise cable or something that is very light weight and does not have external connections this may work for you.

NIC with PCIE 4.0 interface worked at PCIE 4.0 x4 speeds.

Plugged this a raspberry pi 5 and got to detect a PCIe SSD. Plugged into a mini PC with a few gpus and SATA controller and all worked no issues.

can be used if you need a quick and dirty Egpu among other things seems to work perfectly. only thing i did not like about it is it's use of a SATA connector and not MOLEX
