    • Worked without any technical issues. Stiff so take your time during the install
One of the budget options but riser cables don't need to be $60. It works well. Despite having to remove my GPU several times since the build to upgrade my WiFi NIC and to reroute power cables etc. Kinda stiff but be gentle and take your time and you can curve it to your needs. Install was quick, it worked well with my mobo, case, and GPU. Takes up a bit of room so if you have other PCI cards like me, it can cause headaches but again, be gentle and route it and hold it for it to kinda retain the shape and it'll work. Only gen 4 PCI-E, but that's good enough for me. Not gen 5 compatible so if your chasing those 1% lows, don't go vertically mounting the GPU. ... show more

    • Works great, fantastic value

Great riser cable. Works perfectly coupled with an RTX4090. No drop in bandwidth and it works 100% at PCIe4x16. Cable is flexible but not thin. It made a good computer build even better by being able to mount GPU vertically. Highly Recommended.

    • Works with Intel Arc Pro B50 as a secondary card
Size: 200mm Color: Black
Riser cable is working as expected. Plugged into a PCI-E slot and was able to drive a Intel Arc Pro B50 without external power, even though that is a PCI-E 5.0 8x card.

    • Don’t buy cheap riser cables
Size: 200mm Color: Black
Ever since using this cable, my PC would crash randomly, games couldn’t run for more than 5min without crashing or hanging the entire computer, 1 of my 3 GPU fans would not turn on.. it was clearly causing power and communication issues between my GPU and motherboard. After removing this cable and having my GPU back into the motherboard directly for 2 weeks, not a single issue. ... show more

    • Double check your dimensions, it didn't fit my case.
Size: 200mm Color: Black
The Okinos PCI-E 4.0 Riser Cable worked well and handled my 4090 Founders Edition without any issues. Performance-wise, it does what it’s supposed to, and the high-speed transfer and flexibility are solid. It was simple and easy to install, had a standard weight. Its also definitely durable even with zip ties. But it didn't fit perfectly. Even though the specs indicated it would fit my PC case, it didn’t quite line up as expected. I ended up using zip ties as a quick and temporary fix, which worked well enough for the time being. It’s not the most ideal solution, but it’s functional until I find something more permanent. Overall, it’s a good product, but double-check the fit for your specific case before buying. ... show more

    • Great GPU cable for vertical mounting
Size: 200mm Color: Black
I built a gaming computer with the ASUS TUF Gaming GT-502 case. This case allows for vertical mounting of my RTX 4090 GPU. This GPU interface cable works great in my system. Some tips about using the cable, the cable is quite stiff and the cable needs to be in an “S” shape to work I.e., one end plugs into the PCIe slot on the motherboard and the other right angle female PCIe connector for the GPU. So what I did was to “train” the cable to be that “S” shape by folding the cable in “S” shape and put it into a 4” diameter round jar for a few days. After a few days the cable took on that “S” shape and it would not work itself loose from the motherboard or GPU. ... show more
