why make a bulky adapter to replace a more slender and reliable cable that already exists?

As John Hoang points out "600W load requires a 1200W rated CORSAIR PSU or higher. 450W load requires 1000W or higher. 300W load requires 750W or higher. "

As mentioned in my initial post my GPU is supplied with 4 to 1 adapter and works fine with my HX1000 Platinum PSU.

It doesn't make a lot of financial sense to buy a new 1200w PSU just to be able to use the 2 to 1 Corsair Adapter i.e. if the Corsair 2 to 1 adapter is not compatible with all RTX 4090's like mine then why not produce an adapter that does?

but a new 4  cables adapter will not magically turn your PSU into a 1200W one.

the 4 cable squid and the Corsair cable with 2 PSU connectors do the exact same thing. If your 4090 works with the Nvidia squid, it will work with the new cable. it's just a cable. the sense wires on both the corsair and nvidia cables allow the GPU to pull up to 600W of power. the power limit of your GPU will be the same with the Nvidia or the corsair cables.

Corsair recommends a 1200W PSU to have enough headroom for the power transients, with some margin. If your computer does not shut down with your current PSU it's fine.

I'm well aware "a new 4 cables adapter will not magically turn your PSU into a 1200W one."  That would be pretty cool/hot if it could 😛 

My original question was would the Corsair (2 into 1) Adapter work without issue with my GPU which was supplied with a 4 into 1 adapter.

MSI recommend "1000W (Min. 850W)" PSU.

Power consumption of the MSI RTX 4090 Spurim X = 450w in Silent Mode and 480w in Gaming Mode i.e., only 30w over the recommended Corsair spec.

But with many reports of connectors going into "meltdown" I wanted to check for peace of mind if Corsair adapter would be safe and if it would cope (in theory) if the GPU is pushed/overclocked.

the 4 connectors squid is made this way because PCIE cables are specified for 150W each. hence the need to use 4 to avoid overloading one and going over spec (even if in practice thay can take a lot more).

The corsair cable does not use PCIE connectors. it's two feeds straight from the PSU so they don't have that limitation. That's why they use two cables instead of 4 :  300W on each.

In fact you'll have less voltage drop because less connectors are involved. All around it's a way better connexion.

Also, virtually all meltdown occurences were on the Nvidia 4 cables adapter. Another incentive to get rid of it i'd say

Cool, awesome thanks LeDoyen.

Makes a lot more sense now. Thanks for the info 👍
