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.

Ohh mate that was it. I hadn't connected the PSU CPU cable. Now it works: https://streamable.com/9bwg1k

Thank you so much!!

Make sure only the correct mb standoffs are installed and all of the correct standoffs are installed and used. Looks like there is an unused mount in one of your pictures.

Well noticed. I totally forgot to move the 2 remaining MB standoffs. Thank you so much!!
