Asrock H110 BTC Pro+ not booting after 2nd GPU

   Not really sure what else to try here

I have the following

Asrock H110 BTC Pro+ MB
Intel Celeron G3900
4Gb Ram
500gig SSD
3x 1200w server PSU's

On an open air frame

Im following the installation guide and doing this I added 1 GPU (Nvidia 1660 Super) and everything boots fine, I added a 2nd GPU (Nvidia 3060) and everything worked fine, I added a 3rd GPU (Nvidia 3060) and when I press the power button nothing happens.. I remove the 3rd GPU and everything works fine again.

I've tried changing the riser and switching out to different cards including another 3060, AMD 5500 XT, AMD 5700 XT and a 3070.

I've tried adding another PSU just for that 3rd card

Nothing seems to work. As soon as a 3rd GPU is added the board won't power up

Yes the risers are powered and all power connections are made to the motherboard.

Any idea what could be happening here? I see others having similar problems but with higher numbers of GPU's
