[SOLVED] Asrock X570s Shuts Down after 1 minute (No Post)

[tperk100]

Case- Fractal Design R5
MB - Asrock X570s
CPU - AMD Ryzen 9 5900X
PSU - Phanteks AMP series 550 Watt
RAM – Neo Forza FAYE 32 Gig (2x16) 288 pin DDR4 4400
Storage - Crucial MX500 SSD
WD 3 T HDD
All other accessories are currently disconnected.

System powers up with no post, runs for about a minute and shuts down. There are 4 Red Leds that flash on an off, and then stop flashing with 3 of the 4 still lit until auto shutdown.

I am confused about the ATX 8 pin power plug. My PSU came with a cable that has a split connector. It has two 4 pin connectors. They fit into the 8 pin MB connector, so I’m assuming this is correct. Could I have possibly reversed them? If they are OK, where do I go from here?

Thanks for any help

My mistake on the GPU.

However, problem is solved. It ws shutting down because I had not connected the CPU fan. To me it was amazng how hot the CPU got within one minute of idle time. I could not touch it.

Thanks for your replies
