I did't know where to put this, so I put it here. I'm building a new pc and the motherboard is a Aorus ax370 gaming k5 motherboard. I bought a new power supply for it and used the old hard drives from the old desktop, the old Blu-ray drive, and Geforce 1050ti graphics card. I hooked everything up the way the manual said and I didn't get any power. I used the old 1000 Cooler Master power supply that was currently working with my old desktop and couldn't get that to work. The new case was a cooler master master case and it was a little cramped, so I completely rebuilt everything on to the old case. The new power supply still wasn't working and the fan on the power supply wasn't moving. I switched back to the old power supply that was working on the old computer and now it's not working. The fan isn't moving on the old power supply. I'm completly frustrated with my second build. The first build five years ago was really easy and now it's complicated. I need some help with this one.
