I can confirm I am using one cable which splits into two connectors that are connected to the GPU, though this is a semi-modular PSU I can't find where I put the other PCI power connectors, and I don't know if the unit came with more than one of them. So unfortunately I wasn't able to test if that fixed the issue.Make sure you aren't using one cable going from the power supply with two connections plugged into the graphics card. Make sure you have two separate dedicated cables going from the power supply to the graphics card.
Make sure your power settings are configured to performance in Windows control panel.
Lastly if the above doesn't solve the issue, try re-seating the graphics card into the PCI-E slot along with the PSU Cables for it.
I was already on performance mode in windows power settings, and have been so since the start of this thread.
I tried changing the PCIE slot which the GPU was seated in and it yielded much greater GPU usage:
However the GPU is now running at PCI Express X2 Gen 2 speeds as opposed to Gen 3 speeds that it was when seated in the primary PCI E slot in my motherboard.
