I'm assuming you'd connect psu 2 to the gpus, but its important to be sure about this since each psu may be on a different phase so the pci slot and the pci cables must be on the same phase
What is exactly powered by each psu? both psus connect to cpu inputs and cpu pci inputs, but only the first psu connects to the two 8 pin pci power inputs next to the atx input, so because of this it almost kind of seems like the first psu should be the one powering the pci devices (gpu). The manual only says how to connect the two psus to the motherboard but says nothing about what each psu is powering or how to hook up pci devices in dual psu mode

Hi @iedoc ,
thank you for your inquiry. In dual PSU mode, each PSU typically powers different components of the motherboard to balance the load and ensure stable power supply.
Regarding the specific devices powered by each PSU and how to connect PCIe devices in dual PSU mode, we recommend referring to your motherboard manual. You can consult the quick start guide below, which provides detailed connection instructions.
