3D Printed Tool Reinforces 16-pin 12VHPWR Connector While Helping with Cable Management
A Redditor who goes by mikejc shared the 3D printer model for a contraption that safely bends a 16-pin ATX 12VHPWR connector to a 90° angle for cable-management. It's essentially a crutch to guide the high-gauge cables of the connector, which bends the cable at a safe 3.5 cm distance away from the connector. A properly guided cable reduces mechanical stresses on the contacts of the 12VHPWR connector, improving its durability in scenarios where PC enthusiasts want to manage cable clutter in their PCs. The PC enthusiast community was stirred last week to end-user reports of GeForce RTX 4090 graphics cards with burned 16-pin power connectors.

I've noticed a similar problem with some domestic wiring cables. Some of the "cheaper" wiring brands are clearly inferior to the better quality ones, and are "equivalent" in current capacity in as much as they cannot handle overload, and they require cool temperatures, not within insulated conduits.
A 3D printed design might look better, but it's mostly unnecessary. And I think a simple tube like design, with two 3-4 centimeter pieces that can clip to each other will make a better job.
Makes you wonder why nvidia didn't do this.
Right they wanted people top buy new psu's :slap:
1600$ and you have to print accessories so it doesn't melt :D
I wonder if anyone who bought one of these horribly designed cards has been in contact with the CPSC, the EEIE, their local/State Attorney General's office, or at the very least the BBB ?
I know I certainly would have if I had spent $1.6k on a dangerous, worthless pos that should never have been cleared for release to the public in the 1st place..
If you’re that desperate for a card then go get something to hold u over until nvidia gets their shit straightened out.
Please re read my post and understand that I am suggesting that someone can fix the adapter's problem with almost 0 cost. And I say almost 0 cost because I guess 10-20 centimeters of self adhesive tape does come with a cost. Maybe $0.0001.
Also the 3D printed tool in the first post does NOT stop the cable from bending close to the socket. It's even seen in the picture where the cable is free to bend upwards or horizontally. It's not a good design, but it is a good example to offer ideas for fixing this problem.
Gamers Nexus tested 5 such adapters and all of them were built much sturdier than the one Igor's Lab had, which shows that the problem might be very minor.
As for that 3d printed part - 4090 is already a tall card, and this thing probably won't fit to most of the cases on the market.
I have ordered a cable from cable mods. I want it to bofh look good and be safe. That 3d printed part, does not fix the burning/melting problem. A cable from cable mods I hope will fix both of these problems.
The material fail temperature you need to reference is the glass transition temperature (the lowest temperature at which the material can flow or warp), not the melting point. This depends on what material you're using. Approximate fail temperatures for common printable materials are:
- PLA: 60˚C
- PETG, high-temperature PLA: 95˚C
- ABS: 105˚C
- Nylon: 70˚C
- Polycarbonate: 145˚C
As you can see, most of the cheaper printing plastic spools are not suitable for hot rigs.HORSEY
