Yea by specDoubt it. If the AIBs are still working on it, they won't have told retailers and that info is probably still under NDA. If you told retailers now, the spec would leak everywhere because the retailers are customer facing. More likely is some webstore is quoting made up figures, and the rest have copied it just to get preorders. Isn't 375W exactly the max power limit supplied by the PCIe slot plus two power connectors?
75 PCI_E
two 8 pin 150+150
They could go three 8 pin lol but they would get crucified for that.
TBF that's what the FE is two 8 pin. So it would be maxing out its spec at 375.
