FormatC :
The PCI-SIG has to renew their standards, right. But it seems they will keep it as long as possible to be compatible with older hardware. We dicussed it with a PSU manufacturer and the engineer showed me a few PSUs for SI business with AWG20 cables (and bad cable quality) from as Chinese competitor. For this hardware - PCI compatible, is a 6-pin not the thing what I want to have in my PC
The ventilated chassis rating of real #20 copper wire is 11A, which is still higher than Molex's 9A/pin rating for standard MiniFitJr connectors and enough to deliver over 200W at 12V using only two pins.
If the PSU manufacturer is using copper-plated #20 aluminum for 6-pin PCIe, nothing is stopping it from doing the same for 8-pin PCIe. You can't really build meaningful standards based on the behavior of companies who ignore them.
