I have the Asus Prime b250m-A motherboard and would like some help finding where to plug in the front panel connectors and also I am familiar with the CPU power connector being an 8 pin, is it a 4 pin on this motherboard?
The front panel connector is in the manual and it should also be printed on the motherboard. If your PSU has an 8-pin cable (2 x 4-pin locked together), then split it and use the 4-pin cable that fits.
