Review: Works with 40 series - Works with 4090, didn’t impact performance on a handful of benchmarks. I was concerned as the packaging on the TT cable says 16Gbps while the 4090 shows 21Gbps. I checked system info in nvidia control panel before and after install and it’s still reading 21Gbps with the riser installed. I got the 4.0 300mm extender and it fits great in the TT view 51 case. The included vertical bracket that came with the case works perfectly. Directions/instructions are broken English and a bit confusing, if you are looking at buying this item that shouldn’t come as a surprise. If you have a small/mid sized case I might consider something shorter, as this thing barely fits in my case. The cable seems sturdy and well built. There is a small red stripe on each side of the cable for some reason which is a bit strange, but no big deal. This is my 3rd try with a different riser cable over the past few years, and it’s by far the best quality and performance. Note that this only includes the riser cable. Mounting hardware and such will be with your case or you’ll need to order separately.
Review: High grade cable - You have to pay to be the boss. Very nice cable, plenty long and flexible. No issues running card

### ⭐⭐⭐⭐⭐ High grade cable
*by L***N on December 19, 2024*

### ⭐⭐⭐⭐⭐ Good preformance for the price
*by A***O on October 31, 2025*

I used cheaper cables and they just don't work with my core p8 case. They also caused my pc to crash several times. After buying this one, I've never had that issue since
