Hello.
I have a Superflower Leadex III Gold 750W Modular Gold (SF-750F14HG) from about two years ago.
There are only two VGA inputs and two CPU inputs behind it.
If I purchase an RTX 4080S, could I utilize my VGA outputs for both the VGA input and CPU to provide power?

The RTX 4080S needs three 8pin connectors. Your power supply has two cables, each featuring two 6+2pin PCIE connectors. That gives a total of four 6+2pin PCIE connectors, with one remaining free.

Yes, the names CPU and VGA refer to the same components.

It seems you're wondering if a 4080S will work with your current power supply, and if so, whether you need to purchase a different one.

However, relying solely on two PSU inputs might lead to issues. Also, would you really need an adapter for this setup?

Do you include every modular cable with your PSU? Yes. You'll need an adapter - three PCIE 8-pin to 12VHPWR connectors. It's included with all RTX 4080S models.

The VGA cables each contain 6 plus 2 pins. With two cables in total.

These results are designed for 300w.
Each connector supports 150w.
