Asrock WRX90 Evo Dual PSU and GPU configuration details
Consider sharing your insights on whether keeping all PCIe devices on the same PSU in a dual PSU setup is actually feasible. It seems the advice makes sense as long as no GPU or PCIe slot draws power from both units. The Asus board for the same chipset appears to handle GPU/PCIe allocation more flexibly, which makes me question how strict the recommendation really is.
When someone encounters this problem, I reached out to an Asrock support person to verify the advice given for managing power usage on overclocked Threadripper CPUs. It’s safe to leave some GPUs running from PSU1 and others from PSU2, as long as you stay within your power limits and avoid drawing power from more than one PSU to a single GPU or PCIe card. With TR, understanding the CPU’s power draw during full load is crucial because these processors consume a lot of energy.
