XPS 8950, PNY 4080 Super, PSU upgrade

Wanting to upgrade my GPU, I've already purchased a PNY 4080 Super, and I knew I'd need to upgrade the PSU before utilizing, but I didn't think about the difficulty of finding the one I needed before hand haha. The GPU came with something similar to this, but I don't have enough 8 pins on my current PSU nor the wattage to power this thing. Would someone that's done this before or knows Dell parts better than I be able to assist me? I can't get any product details for their 1000w psu that I was going to throw in it. If it doesn't have a 3x8 it does me no good. https://www.dell.com/en-us/shop/dell-1000w-power-supply/apd/rd0g0/computer-chassis-components
Thanks!
