PC dies soon after turning on.

Hi everyone,

I've recently finished building my PC which has an AIO NZXT Kraken X62 cooler, I plugged it into my CPU and connected it to the SATA power connector. The radiator fans were also plugged in to the same wire the AIO waterblock uses (I suppose that is how they get powered, and rather not from the USB port). The PC turned off without getting into BIOS although the motherboard's ASUS logo did appear for a second before dying.

Everything seemed to be turned on and connected, the radiator fans were spinning at max speed and it was annoying while the PC was on. The waterblock's NZXT logo LED was off, however. But the radiator fans were spinning normally, anyone can tell me the possible issues? My PSU is fine as it was self-tested A-OK (it's a Corsair AX1500i PSU). Sounds like possible overheating due to the AIO not getting powered, no?

It is a possible overheating issue, but the CPU wouldn't thermal shutdown immediately, you should be able to make it all the way into Windows before any thermal shutdowns occur.

The fact that you didn't make it very far past POST makes me believe it's a motherboard issue, especially since the AIO isn't turning on and you can't even get far past POST. Which header is the AIO attached to? It should be either on the CPU_FAN or CPU_OPT_WITH_PUMP header, preferably the one with pump.

Full specs.

The AIO is connected to CPU_FAN header, CPU_OPT is connected to a PWM hub on my case which is linked to the front intake fans only.

I know that the motherboard's platform is new (X399), and it could have issues. But why isn't the NZXT logo on the waterblock not lighting up? That implies that the cooler's pump isn't even powered. :/

Cleared CMOS, re-arranged RAM sticks and it worked! Thanks for your help guys!
