I’ve recently gotten a new graphics card to run better games as i realised my last one wasnt good, i’ve found out this graphics card has a 8 pin PCIe port but i cant find the power cable anywhere, my graphics card currently is a GeForce GTX 1660 Super and i just wanted to see if i need to buy an 8 pin PCIe cable as i cant find one anywhere inside my pc and if i do, where do i put it? Videos are greatly appreciated
