Works to save space for narrower cases.
Serves the purpose for newer video card power plugs. A new ASUS RTX 4070 Super card came with an adapter to two standard PCIe 8-pin power plugs, but it was long and stiff and wouldn't have fit in my case. This solves that problem.

Very much Needed with 40 Series Nvidia
Installation was a breeze, I'm glad this was available, and very affordable, I highly recommend this product if you have a 4080 and a smaller case, as it does take pressure off the 12vhpwr connection, and stops bad bending and bad connection, which can cause issues with the 40 series of Nvidia GPU's. Be aware though of there being A & B types. one points up and is what would be used for a vertical mounted GPU and the other points down, to help with cable management. Would consider for any future purchases, especially with how big new GPU's are.

Read carefully
Double check the orientation of the 4 small pins on your GPU (are they on the top or bottom). Seller posted a picture of this pretty clearly (second picture) so my fault for not reading carefully, but this doesnโt work on my GPUโฆ the plug would have to feed in from the top of my card. Apparently the orientation of the 4 pins is different on different GPUs. Giving 5 stars since itโs my faultโฆ but couldnโt use it. Design and build quality seem fine.

Beefy but wrong dorexrion
Beefy and way thicker then it seems. However it points back into the fan assembly instead of out toward top of case like most.

This plug is Great
This plug saved me from my lack of planning. I recently built a new PC where I used a GTX 4090 graphics card in a mid-sized case. That card is a size beast. If I hadn't found this plug I was going have to buy a case adapter from Lian Li for and additional 100 bucks and wait three weeks for it to ship from China. This plug saved me from having to do that.

Not a spec of copper
I had a cablemod 180 deg adapter and it melted itself into my 4080's connector during a few extended sessions. Cablemod allowed me to select any one of their cables as well as reimbursed me for a repair at northridgefix (a famous repair shop on youtube.) BTW, they do great work but, have absolutely horrid communication practices. I was left to worry about whether they received my $1200 card for way too long and they never did answer me about whether there was anything else that needed repaired past the obvious. That's the only 2 questions I asked. I prob overdid the packaging too but they sent it back with far far less. Also, expedited service took 2 more days than stated. I'm sure they're slammed but a simple email would've been great. Just a warning if anyone has to use them. The whole 11 days was very stressful, but I digress; I picked one with a 90 on the end. I found this and thought with the heatsink, maybe I'll be ok. Cablemods version did have a heatsink, just not much of one. This has no heatsink at all. There is a roughly 10x12mm very thin piece of AL on each side of the pcb connected to the ground. I can't rem the size, but if cablemods version with a sink and a thermal pad melted, this one with no such heatsink, thermal pad or anything of the kind to be seen, will surely melt too. I'm not going to use it. I would highly recommend anyone with more than a 4070ti or maybe even just a 70 not to either.

A great solution for the RTX 4090 cards
It is simple to use and keeps the power cable on the RTX 4090 card from being bent. It makes the installation easier and safer.
