Hi Peoples - I am turning over to you for some guidance. The rig boots normally without the GPU plugged into the PSU, either through the PCI slot or through the riser.

However, when I plug the GPU into the PSU, the rig starts up briefly, everything lights up accordingly and seems to be trying to boot, but then about 3 seconds in the rig resets. I hear a little blip and it continuously tries to boot up with no avail. While I intend to hook up 6 gpus (between two psus due to availability on 1000 w plus), I am only trying to connect 1 first. I would think that a 750w psu would be capable without tripping power for 1 gpu?

I've gone through and removed everything and it comes down to each gpu tripping something. Any insights would be greatly appreciated!

Rig has the following specs:
-msi z390 pro MOBO
-i5 9700
-16gb ram - corsair
  • samsung 250 ssd
  • 4 120 mm fans
  • 2X evga 750 g5 gold+ psu
  • Asus Geforce rtx 3070 (will eventually connect 6 total)
