If the way you are calculating the max 375 Watts is by adding the standard specification for those 8 pin connectors and then adding PCI-E wattage, so 150 Watt + 150 Watt + 75 Watt, we have seen in the past that those connectors can provide a lot more power than the standard specs suggest as long as the power supply is capable of it.

For example, if you take two very power hungry cards, the Titan Z and 295x2, both of those only have dual 8 pin connectors. Not more than that yet their estimated power draw is almost 500 Watts. It's why the recommended power supply is 750 Watts at a minimum and it's highly recommended to get 850 Watts or more. And you could overclock those on top of that.

Then I don't understand why everywhere I looked they were talking about "MAX" power over PCIe and the connectors. Where I come from "MAX" means "MAX". There must be a limit where the PSU can't or will not allow more power through any connector, otherwise they might not bother at all with safety.

I actually expected that all high overclocked cards come with 3x 8 Pin.

PSUs are in this respect similar to CPUs: Those with a lower power rating in a series are generally just models who didn't reach the same in testing. PCGH or C'T (can't remember which one, was over 5 years ago) once tested a 450W be quiet! PSU and managed to pull over 800W from it.

However, the PSU won't do this for long - and more to the point, neither would the card, it's power connectors and/or it's cables if they pull more than their designed limit.
