Maybe having multiple cables is a sensible idea due to the newer 12v connectors being problematic, spreading the load over more wires may result in less melting ? Possibly it's better to have 600w split 2x300w(1200w capacity) than 1x600w cable ?

Yes that’s what I was thinking - two cables but 300w each.

Not sure they would go with that, however maximising sales to people who buy a 5090 is maybe not something they need to worry about. Anyone doing that would probably be able/willing to also purchase any additional items (such as compatible PSU) as well, that's how I see it at least.

they wont make sales dependent on the availability of another product not directly under their control.. because it translates to potentially lower revenue
its going to be the same as 4090 and will ship with 12vhpwr to 8-pin dongles

I’m suggesting they will go from 1x4-way pcie octopus adaptor (as per 4090FE) to 2x2-way pcie adaptors.

So 4x pcie would still be ok. No need for a new PSU.

Or you could go with 2x12v cables, no adaptors.

in that case they'd rather adopt 4x pci-e receptors, the 12v was in there to reduce the board footprint
i think a 2x12v design exclusively benefits psus with 2x12v ports - it makes sense if someone already has one of those, but i guess the size of the current installed base will not be enough for nvidia to adopt the design
so i feel as long as the board power requirements are within the 12vhpwr spec, theres no apparent reason for change because it would defeat the primary objective of the port while only benefitting a fringe minority

There is no chance in hell that the 5090 FE card will be using two of those connectors. Aftermarket, maybe, but certainly not NVIDIA’s own. Plus, I doubt they will be using the full 600W, between 400W to 500W probably, but I doubt they’ll push it further than that.

Plus, two connectors are more points of failure on an already poorly designed connector in the first place, so that’s one reason I certainly don’t want a second connector.

Can you imagine how that announcement would go? Here’s our card that’s twice as fast as a 4090, but the requirements will be two power connectors, so you need a bare minimum of a 1000w to 1200w PSU, which most don’t have. So that’s another few hundred, and the card will be £2000+ according to most here. Can you imagine the negative news on that?
