MSI has developed a two-color connector for high-power GPUs utilizing the 12+4 (16-pin) cable. The horror stories about melting connectors that were later explained as user error are something we all remember. Some people had difficulty fitting the cable all the way into the connector, which was a direct cause of cables overheating and melting.
As demonstrated by PCWorld who are visited the MSI booth at Computex 2021 fair in Taipei, the company might have just ‘solved’ this problem. The company came up with a yellow connector cable for its modular power modules. The idea is plain simple, as long as the user can see the yellow part, then the cable is not inserted correctly. The only way to hide the yellow part is by plugging the cable all the way down until there is only the black part of the cable is visible.
 
PCWorld were given two cables to demonstrate how this works and MSI MAG 850GL PCIe Gen5 ATX3.0 power supply. The supply is not relevant here because this cable can be used by any MSI product, and it is designed to be two-sided. This means that the yellow part will act as a safety measure not only for the supply but also for the graphics card, which is probably more important to note anyway. This novel idea for the high-power GPU cable is also very cheap to implement by other vendors. It requires no major changes to the design of the connector, while it ensures that users are plugging the cables correctly. If only NVIDIA came up with this idea sooner.
 
It's a very simple, but clearly understood idea. 
 

Next up, labels on things like Bleach "Do not ingest"

I just received a notification of PCI-e power connector change in accordance to PCI Express Card Electromechanical Specification Revision 5.1 from Amphenol as of June 1, because I bought connector from them before.
(As of this moment, the revision 5.1 document isn't yet listed on PCI-SIG site, by the way.)
 
Looks like pins length and locking mechanism will be updated to address existing 12VHPWR issues.
 
Notable changes:

• Modification of Power and Sense pin length
• Modified mating Interference dimensions and tolerance
