Cores not activated

I have just bought a Ryzen 5 5600G and an ASUS Prime B550M-A motherboard. When I open the BIOS it registers all 6 cores, but Windows task manager only reckognizes 4 and when I enter msconfig it also only displays up to 4 cores. Any idea how to fix this. Also my power supply only has a 4-pin connector for the CPU, so could this be causing the issue?

Try updating to the latest Motherboard Non-Beta BIOS Version available and also update your AMD CHIPSET drivers from here: https://www.amd.com/en/support/chipsets/amd-socket-am4/b550

If you have the latest BIOS already installed then do a CLEAR CMOS to reset your BIOS back to factory defaults and check afterwards if Windows is showing all 6 cores.

Also in BIOS Settings check to make sure all of your Processor's core are enabled and none disabled or locked.

Also check your Windows Installation by running the following command line in a Elevated Command Prompt or Powershell. You can copy and paste it into Command Prompt or Powershell if you want:  SFC /scannow

One way to verify your AMD Processor core is by downloading and installing Ryzen Master app. It will give you a lot of information about your AMD processor including if any cores are locked or not.
