Question Question about new GPU into existing system

[Bsmooth]

Right now I'm using a GTX 1050 Ti and I want to go from a 1680x1050 to a 1440 monitor, I am looking to get an ASUS TUF Gaming GeForce RTX 4070 Super OC.
This is what I have for a system;
Motherboard: MSI MPG Z590 Gaming Plus, BIOS: 7D07 VA2

VGA: NVidia GTX 1050Ti

PSU: Corsair RM750x

CPU: Intel? Core i5-11600K

MEM: 2x8GB, 3600MHz G.Skill Ripjaw F4-3600C16D-16GVK
My question is the connector to my present PSU and the problem I've heard of melting cables. From what I understand the Asus card uses a 16 pin connector which I don't think my present PSU has. What type of cables do I need to connect my new Graphics card, and who makes good ones ?

That GPU includes an adapter in the box.
It will convert 2 x 8 pin VGA connectors to the new 12V HPWR connector.

I recommend simply using that instead of buying after market adapters.

Only reason I ask is that I thought it was a 16 pin, and that also that 12VHPWR was the one that melted.
