Cablecc Oculink SFF-8612 SFF-8611 to PCIE PCI-Express 16x 4X Adapter with SATA Power Port for Mainboard Graphics Card

I purchased this thinking it would fit better in my oculink egpu enclosure than the 24pin ATX model as it was listed as working with graphics cards. It did not work with my RTX 4070 and the main reason i think this is, is that after researching, I do not believe Sata can deliver enough power through the pci-e slot for a modern graphics card. I ended up going back to the 24pin atx connector and using a 90 degree angle adapter to get it to fit. My guess is this is for other pci-e cards like wifi network or sound card etc. Thankfully I returned it and got a full refund without problem. They should not list graphics cards in its description in my opinion.

I've installed a lot of these at work, and they're great for what we need, but it can be hit or miss depending on your setup. The SATA power limit hasn't been an issue even up to running 5090s - big GPUs generally draw most of what they need straight from the PSU rather than through the PCIe slot. Knocked off a star because the power connectors are flimsy, even considering the low cost. They're just held in place by the solder pins and easy to snap off if the SATA connector is stiff or if they get knocked about in shipping. There should really be adhesive or a couple of M3 bolts on there for mechanical strength. They seem to work well with x4x4x4x4 bifurcation adapters on CPU-direct PCIe lanes, and hit gen 4.0 speeds no problem with high quality oculink cables. The PCIe speed needs to be set to 4.0 specifically in the BIOS (or 3.0 if you're still having issues), our systems won't boot at all if it's left on auto but are totally solid when set manually. Using them with NVMe adapters or slots that use chipset PCIe lanes seems to be a lot less reliable, so it's pretty much down to luck if that'll work for your specific motherboard and GPU or not.

"Powered" by a single sata connector, but SATA connectors don't provide enough current for a PCIe slot.

couldnt get it to work on my HP's onboard oculink port, but could be the mothboard

M2-oculink変換基板からoculinkケーブルでつなぎ、4Xカードを挿して動くことは確認。ビデオカード系はまだ動かせていません。

Really poor quality. The power pins socket snapped off when connecting solder joints.

This oculink board works perfectly, plug-and-play, with the oculink port on the Minisforum UM780 XTX.

残念ながらM.2 NVMe SSD 2TBを接続してみたが認識できなかった。M.2 SATA SSD 1TBは接続しちゃんと認識して使用できる。

Utilisé avec une rtx 3070 et une gpd win 4. Fonctionne parfaitement, reconnu aussitôt.
