I am running a 6x3090 workstation using 6 server power supplies and breakout boards. The power supplies are rated at 800 watts. Each power supply is set up with a breakout board and there is one power supply for each gpu. Each gpu has 4 6 pin pcie cables feeding it. The computer is run off 4 1800w enterprise double-conversion ups, with each of these on its own 120v 20 amp circuit. I mainly use the computer for training image segmentation models where it crashes every 24 hours of training or so. When running blender its crashing every few minutes of rendering. What might be causing this? Let me know if you need more information.
