I’m new to pc building so this might kinda sound stupid. So I put my hard drive into my pc and plugged in the power to it but I need to plug my sata cable in somewhere. One side of it is plugged into the hard drive so where on my motherboard does the other side go. This is probably really simple and I’m really stupid. Thanks!
