Review: Works well, solid build - Works well, and constructed well. I would opt for the one with power supply along with it, but to save a few bucks, rock solid unit. Review: Inexpensive and works, I'm an Oculink believer now. - Works. Nice that includes the m.2 Oculink adapter. Be sure to buy an Oculink cable. I have a mini PC that only has (1) M.2 PCIE x4 4.0 slot, so I had to clone my MVME to SATA drive. Comparing FPS with games that struggled, it's apparent that Oculink > USB4/TB4. I wish this had a Power supply mount, and that the Oculink port was more accessible towards the bracket of the graphics card. The power switch on Auto didn't work, so I toggles it to On. Works like a charm. There's potential to 3d print an enclosure. Install notes: ONLY plug your power supply to the 24-pin connector (check/green). DO NOT connect power to the connectors circled in res (X/red). If your GPU requires PCI-E power, plug those power supply cables directly to the GPU power connectors (not dock). ## Features - Oculink-Compatible adapter board, support devices with O culink port to expand PCIE card. - Support M.2 port, through the standard O culink extension cable to PCIE card. - Support expanding GPU graphics card, PCIE network card, PCIE sound card,?PCIE capture card, etc. PCIE array card only supports X4 devices. - Support ATXSFXsmall 1U power supply, the adapter board only needs to be inserted into?the 24P power supply, the graphics card power supply is provided by other power supplies.??Power supply should be 500W and above. - This series of boxes do not support built-in power supply, and limit the size of the graphics card.

The only problem I had was the I couldn’t get it to turn on using the turn on with pc startup so I had to set it to be on 24/7, but that wasn’t exactly a problem for me since I intended for the pc to never turn off since it runs a whole bunch of servers ## Frequently Bought Together - JMT M.2 M-Key to PCIE 4.0X4 External Graphics Card Stand Bracket Compatible with Oculink/M.2 NVMe Laptop eGPU?GDP Handhelds (Dock-OC4) - chenyang SFF-8611 Cable OCuLink PCIe PCI-Express 4.0 SFF-8611 4i Male to SFF-8611 Male Data Extension Cable 50cm for eGPU GPD Win Max2 External Graphics Card & SSD - CY Cable OcuLink PCIe PCI-Express SFF-8611 4i to OcuLink SFF-8611 SSD Data Active Cable 50cm --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kg/products/604015681-m-2-m-key-to-pcie-4-0x4-external-graphics](https://www.desertcart.kg/products/604015681-m-2-m-key-to-pcie-4-0x4-external-graphics) --- *Product available on Desertcart Kyrgyzstan* *Store origin: KG* *Last updated: 2026-05-10*
