I was trying out the Asus AI Overclocking. It put a 38% bump on the 9900K. In Prime95 Small FFT, the CPU was hovering around 80c. The temperatures and noise were actually acceptable. I was surprise that bottom intake is actually quite decent in the Cerberus. However, at that OC, the power consumption was over 240w. I tried a few other tests, but all of a sudden the PC froze. I thought no biggie - let's dial back this OC manually, and get the PC back to a stable state. Did a hard shutdown.
Upon turning the PC back on, the PSU would click, fans spin for a half second, and then turns off.
It was too late in the night to start troubleshooting. I just hope it's not the PSU (new Corsair 600w Platinum), or the MB (new Strix Z390i)...
