Question Doubt about my PSU entrances

[wandererlost]

Hello.
I got a Superflower Leadex III Gold 750W Modular Gold, (SF-750F14HG). I bought it about 2 years ago.
Behind it there are only two VGA inputs and two CPU inputs.
If I buy an RTX 4080S could I use my VGA inputs on both the VGA input and CPU to supply power?

RTX 4080S requires three 8pin (6+2pin) connectors.

Your PSU has two cables, each with two 6+2pin PCIE connectors.
So - four 6+2pin PCIE connectors total. One will be left free.

So the name CPU and VGA doesn't matter? Are they the same entries?

Are they the same entries?

No, the pinout is different.

No, the pinout is different.

So I can't use a 4080S with this PSU? Would I have to buy a new one?

You can use it. Do what @SkyNetRising suggest

But won't it cause damage by using only two PSU inputs?

Besides, I would only have to use it with an adapter, right?

Do you have all modular cables with your PSU?

Besides, I would only have to use it with an adapter, right?

Yes. You'll have to use adapter - 3x PCIE 8pin to 12VHPWR connector.
It comes bundled with all RTX 4080S.

Yes. The VGA cables each have 6+2 pins. There are 2 cables.

Those are outputs! Each output is rated for 300w.

What do you mean?

Yes. The VGA cables each have 6+2 pins. There are 2 cables.

Each connector is rated for 150w.
