Hi, just installed a new PC with these details:
Mobo: Asrock B760 Pro RS/D4
CPU: i3-12100f
GPU: MSI GeForce GTX 1650 Aero ITX
RAM: Corsair vengeance rgb 3200mhz cl16
SSD: Lexar NM710 NVMe
Case: NZXT H5 Flow rgb
PSU: Cooler Master G750M
When I power it on, all fans spin and everything works fine except for the lack of a display and the CPU cooler fluctuating unexpectedly. I’m unsure what to do.
Could it be that I’m missing the ATX 12v2 port on the motherboard? My PSU doesn’t have an extra cable for that?
Help would be greatly appreciated!

The PSU in the build above is not old. If it doesn't have the required cables, it might be due to incorrect components or a mismatched PSU.

I saw that the second cpu connector is meant for overclocking and high-power processors, but the i3-12100f isn't suitable for overclocking or power-hungry chips.
