The minimum required amperage rating per working pin of a 6-pin plug is less than the minimum required amperage rating per working pin of a 8-pin plug. Each have the same number of pins which do actual work, but the minimum quality requirement of the 8-pin plug is higher. In order to meet a 450 watt rating for the adapter, it must use three 8-pin plugs. It's a matter of standards. I don't know what is causing confusion.
No. Just no. On both 6-pin and 8-pin pcie plugs each pin is specified for 75 watts minimum each.
That's funny. Can you provide a source?
You are also the only one stating that the hypothetical adapter has a 450 watt rating.
There are news articles every day with manufacturers announcing these adapters with a 450 to 500 watt rating.
The problem is that instead of just answering any questions thrown at you, you use conversation derailing tactics by using a combination of deflection, projection and world salad with some catchy keywords thrown into the mix.
I am answering you. Most questions at least. The question of why 3 instead of 4 or 2 was just insane. It doesn't need to be answered. Serious questions only.

So how does a three 8 pin connection feed into a 16 pin connection? It clearly states it “is not designed to mate with legacy PCIe connectors” so the entire question still stands. Why is gigabyte saying 24 connectors will be required? Will a PCB connection be involved to transfer from three 8 pin connections to a mini 16? Will these new PSU’s only be able to utilize a single pci 5 connection due to incompatibility with old cables, or will the PSU manufacturers just try to hide the fact they are only using the dual 8 pin connections like NVidia already does? These are the answers I would like to see in schematics, because currently it states the old 8 pin connection are not compatible with the new connection, and that limits using older PSU’s with new GPU’s

well.. with the price power of electricity rising every year...
No kidding and people want electric vehicles. The price of electricity is going to be bonkers, heck my house is already at $0.1629431078249269/kWh last time I checked.

The way I look at it is the 12-PIN needs 850W or higher power supply.
750W and under = 2 x 8-PIN
850W and over = 3 x 8-PIN
Using 2 x 8-PIN from a 850W should be OK still 850W.
Using 2 x 8-PIN + pigtail (2 + 1) is still 750W.

My guess is that PSU manufacturers will start releasing dedicated modular cables with 12vhpwr outputs that plug to the 8-pin inputs of the PSUs.
Most modern modular PSUs seem to use hcs terminals for their modular cables, at least on the PSU, so you could just use cables with two 8-pin connectors to one 12vhpwr connector.
Then there are the transient response requirements. Just because the cables work without overheating does not mean that the PSU can handle these GPUs without shutting down or frying GPUs.
Personally I expect to see in-cable capacitors on at least some of the dual 8-pin to 12vhpwr cables. We shall see... eventually.

Just checked ours.. $0.164603/kWh + a list of surcharges every month. Last month was the highest power bill we've ever had for this time of year.

It appears to me that the adapter (cant find any details) will be limited to 450W ..... this is a standard load for (3) 8-pin PCIe power cables The only way to get the 600W from that 12-pin ... those 4 signal wires - require that signal to boost the power from the PSU .... there is no mention if the GPU will also be limited to 450W without signal on those 4 "magic wires" (excerpt OP link) "In order to comply with the 600W specs, the cable needs to have 12 wires for the current and 4 data paths for the signal. The data connectors ensure that the connection has been established and the card actually requires more than 450W of power. In case those data signals are not present, the power supply will feed up to 450W of power."
