I am currently moving my prebuilt Dell into a new case ( I know I know prebuilts). The PSU is my only issue. It’s 24 pin connector only has 23 pins. I’ve read this was removed with “modern” PSU’s for something called a -5V Rail? My new MOBO 24pin connector contains all 24 pins. Will this be an issue or can I just plug it in and be fine? I hope I won’t have to buy a new PSU, 850w isn’t cheap.
