New PC build with Z790 PG Riptide but can't post

I am building a new PC with these components

Open Box: ASRock Z790 PG RIPTIDE Intel LGA1700 ATX Mainboard
Intel Core i5-1300k
G.SKILL Ripjaws S5 Series (Intel XMP 3.0) DDR5 RAM 64GB (2x32GB) 6400MT/s CL32-39-39-102 1.40V Desktop Computer Memory UDIMM - Matte Black (F5-6400J3239G32GX2-RS5K)
Crucial T700 2TB Gen5 NVMe M.2 SSD
Thermalright Peerless Assassin 120 SE CPU Air Cooler
SAMA 650W Power Supply 80 Plus Gold Full Voltage Full Modular ECO Mode 12V FDB Silent Fan
Antec Performance Series P101 Silent Black 0.8mm SPCC ATX Mid Tower Case

I meticulously got everything put things together. It's been a while since my last build (2013) so the m2 SSD was new to me.

So upon first attempt, the motherboard had a red light at the bottom and CPU fans were spinning so I turned off and looked that up and indicates something is wrong with either the CPU, memory or storage. On first attempt I only had ATXV12V1 plugged in, thought the m2 needed power but first tried removing the Crucial T700, now there was no red light but no post.

Also, I am relying on using the onboard graphics using the HDMI port via the CPUs Intel® UHD Graphics 770 GPU

I then tried all of these without the m2 T700 installed

swapping the memory locations A2 > B2, B2 > A2 same
Single memory module in B2
plugging in ATX12V2
Remove/put back battery
Reset CMOS with jumper
plugged in an old SATA drive
All of these attempts result in the motherboards Intel Z790 chip cycling through different colors when the power to the PSU is turned on, then a faint beep from the PSU when the power button is pressed but nothing else happens, no fans spin, nothing.
