SOLVED by @jj122@lemmings.world

Make sure all power connections on the mb are made (there are more than just the 24 pin).

I hadn’t connected the PSU CPU cable. Now it works: https://streamable.com/9bwg1k

Also thanks guys for suggesting the dual channel slots spacing between the memories.

Thanks everyone. You're all wonderful.

What components did you use?

It appears that you don't have a GPU. My guess would be you have a CPU that does not have integrated graphics meaning there is nothing to drive the HDMI and the motherboard can't post.

CPU is an i9-12900K. It has Intel® UHD Graphics 770 according to https://ark.intel.com/content/www/us/en/ark/products/134599/intel-core-i912900k-processor-30m-cache-up-to-5-20-ghz.html
