Seagate IronWolf Pro 10TB won't spin up/detect in bios

[Zedan]

Hi all, 

I have been testing unRAID free trial on an old Dell Optiplex and have been very happy with how it has been working however, I have bought a 10 TB Seagate and I can not get it to spin up under PSU power and it won't detect in the BIOS of my mobo. If I put it in an external Caddy the drive will spin up and show in Windows where I can initialize and format it as needed. 

MOBO: Asus Strix B560-i
CPU: i5 11400
Drive: IronWolf PRO ST10000NT001

Any Ideas on what I am doing wrong?

Try using a 'Molex to SATA power adapter'.  This adapter does not supply 3.3 volts to the drive.   There are a few HD's which use one of the 3.3V supply terminals as a reset signal when if is high.  (No 3.5" drive requires 3.3V as a supply voltage.)
