MSI PRO B650-P WIFI

[body2pg153e02d7]

Good morning,

I have recently acquired the MSI PRO B650-P, an Ryzen 9 7950x and 4 x 16GB g.skill trident z5 neo ddr5-6000 cl30 , RADEON RX 580 video card and my old Corsair AX750 power supply.

I want to mention that the board has 2 cpu powers 8 x pin each (but i have at the moment only 1 x 8 pin connector from my PSU which I connected to the motherboard)
Now I've put everything together but when I turn on the pc, the CPU (RED) and RAM(YELLOW) they stay solid and doesn't boot,.

I've tried to take out the ram one by one, I've kelp one and move it trough all slots, I've taken out the CPU, I've taken out both ram and CPU, I tried to take out the GPU, but nothing.

I've run out of ideas, can anyone suggest anything, please?

I have the impression it might be mandatory that the board has both COU 8xPin connected?

Any suggestions are welcome.

Please try to boot up the system with minimum settings by connecting only one stick of memory on DIMMA2 slot and clear CMOS by shorting the JBAT jumper for 5-10 seconds to check whether the system could boot.

Still the same.

Can the motherboard boot in any way without a cpu?

Only one cpu 8-pin is required to get working. 2nd one is optional. I did this on my build.
To clear cmos, disconnect the power, press and hold clear cmos button for 20 seconds if the board has such a button. If it doesn’t have one, keep the jumper short for 20 seconds.
1st boot after clearing cmos takes long. Wait for 5 minutes to see if it works.

No. But you should be able to update bios without cpu.
