Molex 16 Pin Wire Connector, Harley BLACK Waterproof, Sealed Kit, MX150

Product Information

Another interesting bit of information from the draft concerns temperatures on the 12V-2x6 power connector's pins. The temperature life is 168 hours at 105 degrees Celsius, while the expectancy is 92 hours at 105 degrees Celsius with preconditioning. Therefore, manufacturers must consider temperature limits when designing their graphics cards to ensure that other components, such as the shunts, VRM, or coils, don't add unnecessary heat to the header. Some companies are already announcing new adapters for the GPU. CableMod, for instance, has a right angle adapter that it says requires less bending. What has Nvidia said about all of this? Amphenol ICC confirmed that the connector is designed for 600W graphics cards. It didn't specify whether it's for gaming or data center graphics cards. However, the company did list AI and cloud, gaming consoles, graphic interface, networking, server and storage as potential target markets for the connector. Up to now, we've only seen complaints from consumers using the bundle 4x8-pin to 1x16-pin power adapter. ATX 3.0 power supply owners seem unaffected. These power supplies already come with the 12VHPWR connector, so adapters aren't needed. On the flip side, there aren't many ATX 3.0 units on the market, and they are expensive. The specifications for the 12V-2x6 power connector aren't final; however, Igor's Lab believes they're unlikely to change. For example, MSI has already launched new ATX 3.0 power supplies with the 12V2x6 connector. The fact that the vendors can spec the 12V-2x6 power connector for 150W or 300W might mean that we could potentially find the new power connector on lower-end graphics cards as well.

We do not know precisely how many RTX 4090 cards have been sold that use the 16-pin 12VHPWR connector. There are also RTX 3090 Ti and RTX 4080 cards that also use the same connector. By that token, there could be hundreds of thousands of cards with 16-pin connectors now in the hands of consumers, and only a very few of those have failed — Gamers Nexus claims the graphics card companies are saying the failure rate is between 0.05% and 0.1% right now. So about one in a thousand to one in two thousand. The new connector helps eliminate the use of multiple 6-pin or 8-pin PCIe cables, decreasing cable clutter and making cable management easier. Nevertheless, the GeForce RTX 3090 Ti can also be powered by three 8-pin PCIe cables, although it would be a lot more unwieldy. We are investigating additional ways to ensure that the connector is secure before powering on the graphics card." Initially, there were some concerns that the 12VHPWR connector could fail if the cables were bent in the wrong place. CableMod, a third-party cable manufacturer, published a "12VHPWR Cable Guide" claiming that it can't be bent near the plug, and all bends should start at least 35mm from the connector. PSU manufacturer Be quiet! places that distance at 40 mm. This is difficult to do in most PC cases. It also suggested that people need to ensure they're plugging in the cables completely.Prior to that official statement, there were plenty of theories (some of which, it seems, ended up being right.) With Ampere, Nvidia pushed the 12-pin PCIe power connector, but it never caught on. Only the Founders Edition utilized that connector. The chipmaker's partners still preferred the standard 6-pin and 8-pin PCIe power connectors for their custom Ampere offerings. The introduction of the 12VHPWR power connectors will be troublesome for power supply manufacturers. They'll either have to design new products that comes with the 12VHPWR power connector or provide existing owners with an adapter.

Interestingly, Nvidia has used a 12-pin precursor to the PCI-SIG 16-pin connector on the Founders Edition RTX 30-series cards. To our knowledge, no one reported any melting 12-pin adapters over the past two years. RTX 3090 Ti cards also use a 16-pin connector, but they still come with a 12-pin adapter cable. Our findings to date suggest that a common issue is that connectors are not fully plugged into the graphics card. To help ensure the connector is secure we recommend plugging the power dongle into the graphics card first to ensure it's firmly and evenly plugged in, before plugging the graphics card into the motherboard. Some RTX 4090 owners have reported that the 16-pin 12VHPWR power adapters have melted while plugged into their graphics cards (some also claim that the connectors have melted, too). Nvidia has suggested that the issue is caused because 16-pin adapters are not being plugged completely into the graphics card. AMD doesn't use 16-pin connectors–at least not yet. When it launches its next-gen GPUs, the Radeon RX 7900 XTX and 7900 XT, both will use dual 8-pin power connectors, which means that people won't have to deal with adapters at all. What about older cards with 12-pin adapters?As our brand is known for highest quality standards, we treat this seriously and have initiated an investigation.

The PCI-SIG (Peripheral Component Interconnect Special Interest Group), which is in charge of the spec for the 12VHPWR connection, sent a brief statement to the press on Dec. 1, that in short tells companies making graphics cards to conduct better safety testing. This came after a class-action lawsuit was filed in California. Updated 10/26/2022 9:00 pm PT: Added the relevant information about the usage of third-party adapters from Nvidia documentation included with the GeForce RTX 4090 Founders Edition. So far the melting 16-pin connector issue was affecting mostly the GPU side as you can see in the image above. However, we now have the first case of a Reddit user Shiftyeyes67k who had a 16-pin melt on the SMPS side. The affected model happens to be a 1000W Dark Power 13 from Be Quiet. Here's what we know about the issues with the 16-pin 12VHPWR connector incidents so far. What is happening?When Nvidia launched the RTX 4090, the card was almost universally praised for the performance uplift it offered while also being not very expensive compared to its predecessor, the RTX 3090. In fact, the RTX 4090 is probably the most recommended card among all the other RTX 40-series GPUs, except maybe the 4070, as most of the Ada Lovelace (RTX 4000) GPUs offer terrible value. MSI recently came up with a simple yet somewhat effective solution for the issue, where it showed off bright yellow colored 16-pin power connectors. The idea is that the yellow-colored pins will not be visible to the user once the connector is properly seated (via PCWorld YouTube). Gamers Nexus couldn't replicate the melting issues at first, despite mangling several adapters. It put up a poll for 4090 users where it appears less than 10% have the 16AWG 300V wires. More recently, Gamers Nexus published a video where it "successfully" caused at least one adapter to melt… by not plugging the connector in all the way and by putting strain on the cables. This is murky territory. In the box for the Nvidia GeForce RTX 4090 Founders Edition, the documentation reads:

Nvidia and our partners are committed to supporting our customer and ensuring an expedited RMA process, regardless of the cable or card used.”It replaces the 12-pin plug that was on previous GeForce RTX 30 series Founders Edition cards and can provide up to an incredible 600W of power to the GPU. In comparison, older 8-pin connectors only supply up to 150W each. Despite the PCIe 5.0 connector having 16 pins, its overall size has still been reduced to something similar to that of the older 8-pin connector. The distance between the power pins has been reduced from 4.2mm to 3mm, and the connector measures just 18.85mm long. It's not tiny, but it still occupies much less space than three 'traditional' 8-pin PCIegraphics power connectors. Here are some of the first pictures of a GIGABYTE GeForce RTX 4070 Ti custom-design graphics cards, the RTX 4070 Ti AERO. GIGABYTE targets the AERO brand of graphics cards, motherboards, and notebooks, at creators who like to game, hence the product design that's a lot less flashy than the company's AORUS or Gaming OC brands of graphics cards. An interesting aspect of this card is that it features a 16-pin ATX 12VHPWR connector, and includes an NVIDIA-supplied power adapter that converts two 8-pin PCIe power connectors to one 12VHPWR. We know this adapter is different from the 2x 8-pin to 12-pin adapter NVIDIA included with the RTX 3080 Founders Edition, looking at the four sensor pins.
