I just purchased a seagate 8tb barracuda drive to install alongside my SSD's, but no matter which cable i use the PSU wont power on unless the SATA cable is disconnected from the drive. i've RMA'd the drive once already thinking it was a bad drive but the new drive produces the same problem. The PSU "clicks" and the lights flash on the motherboard and then it immediattly turns off. I'm not really sure where to troubleshoot from here.

Edit: The motherboard in question is an Aorus Master with 2 x 1TB nVME SSD drives in the top and bottom m2 slots. Does that have anything to do with it?

This is one of two things:

1. You're not using a Corsair SATA power cable. The "click" is short circuit protection because cables from other PSU companies are not pinned the same way.

If you ARE using a Corsair cable, then the problem is #2:

2. The HDD supports PWDIS and sees +3.3V where there should be no wire. Solution here is to cut the +3.3V wire, pull that pin out of the connector, etc.
