I was a little scared by the comments of other users, but in the end, I decided to buy it. So far, I have no issues. It just needs a good connection both from the power supply side and the card side. Maybe with a small screwdriver, you can push the tabs up to make sure it clicked in. It is indeed very convenient because you get rid of the mess of the 2 8-pin cables, you do better cable management, and definitely, the graphics card experiences less pressure. I used it to connect a 4070 super gaming x slim with a Corsair RM650 power supply

I didn't expect such poor construction, the equivalent from bequiet is 5 times better in construction. What a shame :(

A convenient adapter to avoid having many cables. The manufacturer of my card seemed to be of higher quality, but I had to connect 3 pci-e cables. The reason I give it 3 stars is that it loses contact with the slightest movement and the card doesn't work, something that never happened with the manufacturer's cable.

Very good connector with a "tight" lock!
The cable is quite stiff, it needs testing before installation and careful bending (NOT FOLDING!) using a thick marker to give it the proper shape and then connecting it to the power supply and card.

Installed on Corsair TX750M (semi modular) with the Asus TUF 4070Ti gaming OC graphics card.

Keep in mind that cable manufacturers do not provide unlimited plug and unplug options. When the card draws 300 watts, a worn-out pin can overheat at the point of poor contact. Always check the connectors and if they appear worn out, it is advisable to replace them!

So far, I have no problems.
It concerns the Corsair RM850x 2018 series PSU.

Update 26/8/2024: there is still no sign of malfunction or damage to the cable or the card.
