Question New build is not powering up ?

[Danny7928]

Motherboard: ASRock B650M Pro RS
CPU: Ryzen 5 7600X
GPU: Radeon RX 7800 XT
RAM: G.Skill Ripjaws S5 32 GB (2 x 16 GB) DDR5-6000 CL36 Memory
PSU: Corsair CX650M (2021) 650 W

BIOS: 1.28

Everything is brand new, help would be greatly appreciated

All I have done before attempting to power up was, setting up the M.2 Nvme SSD, add in the 2 ram sticks in A1 and A2 slots, put in the CPU, and CPU Cooler, then I added in the 24 pin
to ATXPWR1 and 8 pin to ATX12V1. When I turned on the PSU, the motherboard LEDs turned on but when I attempted to power on the board using the System panel header (PWRBTN# and GND)
using my case's POWER SW cable, nothing happened, the CPU fans did not turn on, or anything else. I then attempted to use my screw driver to manually click on the power button, but nothing happened too.

TLDR: PSU plugged in, motherboard light turns on, power button wont boot pc

Steps that I have done:
1. Completely removed the CPU cooler and checked the CPU's orientation was correct and checked for damages.
2. Re-plugged the CPU Fan coolers into the correct CPU Fan pins on the motherboard.
3. Tried removing the RAM and only putting one at a time.
4. Checked to see if my power cables were plugged in correctly and in good orientation

While it is preferred to use the memory in A2 and B2 when in a pair that should not cause a no boot.

With no boots, I generally resort to a bench build -- I build it on my desktop on a sheet of cardboard or the motherboard antistatic wrap. It is easier to change parts and takes the case out of the potential list of issues (shorts, bad start button/cables). It also makes it very easy to see that everything is connected exactly where it should be.

Also, what is the full model number of your memory? Does G.Skill list your board under the compatible boards on their compatibility PAGE for that model?
