[SOLVED] B450f strix 8 pin connector problem

[a.dweik.99]

Hello guys . Today i got my a new b450f from rma. So i run the motherboard on the box. It worked fine. But when i bulid the pc the 8 pin connector seems like not giving a power to ram and debug lights and cpu. But i feel heat coming from my cpu.
The mobo turns on and the fans spins normally but usb outputs are not giving any power to the keyboard and mouse, debug lights are not turning on, but i feel heat from the cpu. What is happening??

What PSU are you using ? It might be case that your PSU can't handle your MOBO

Are you sure you're using the correct connector, the 4+4 and NOT the 6+2, in the CPU/EPS socket?

Yes, it didn't work but i wonder where is the cpu heat is coming from. I have run the rma mobo on the same power it worked fine

If your system ran fine in benchmode then you may have a short from chassis to MB.

So its dead now?

Not necessarily. I have had that situation and placed tiny fiber washers at the MB support post which fixed the problem.
Debry or a lost screw can cause a short
