I've seen people mention concerns over adapter cables overloading the power supply, and recommending to buy an ATX 3.0 one instead. And the limited amount of times you can plug/unplug the cable.

Would there be any issue with using the adapter with a 4090 for example?

So how come the adapter needs 3 seperate 8-pins on the power supply, but the dedicated cable only has 2?

This cable plugs directly into the PSU via our type-4 connector, each of which will push well beyond 300W. This is why only 2 connectors are needed.

 

The adapters shipped with the GPU's are reliant on PCI-e specifications and must take into account that each of the 8 pin PCI-e connectors might only be able to push 150W.

The 3x8-Pin Adapter is rated for the intended 450W. So it needs 3x150W.

But Type4 PCI-E Cables of Corsair are 1x8-Pin to 2x8Pin Cables (daisychain), meaning each 8-Pin Connector on the PSU-Side is rated to provide upto 300W.

Thus the 600W 12VHPWR cables only needs 2x8-Pin on the PSU side.

 

On that note, I intend to run a 4090FE with the SF750 PSU, since there is no higher SFX PSU from Corsair...yet.

I do have a Powerbudget of 550-600W left for the GPU, so it should work.

The question is WHEN you (corsair) be releasing and ATX 3.0 PSU? Personally I don't care of adapters / your better adapter I just want the right PSU , no round the corner solutions just the best conditions for the GPU if I will ever considering buying one. So yeah an estimated date would be really helpful , I know there's already other big brands that have the new PSUs already so why its taking so long for you guys?
