If you have a 40 series card, you'll need the new new new strimer plus v2 12VHPWR.

But there are 2 types. One from the traditional eps connections to the new 12v and the 12v to 12v extension. You'd get the one that fits your PSU. https://www.amazon.com/Lian-Li-Strimer-Plus-12VHPWR/dp/B0C25RCW71

This is the one you want for your PSU and GPU combo.

And this is the one for the motherboard. It also comes with the controller so you can plug the GPU strimer in it.

No, the one you linked it for a GPU that uses three 8-pin power cables, like the 30 series cards or some of the 7900 XTX cards. I don't have a link for a source in Chile, but this is what you're looking for. It should have the 12VHPWR connector on one end.

So this will work for a 4070ti?
