My setup is the following:
- Regular PSU to power only the motherboard+CPU - Server PSU to power all GPUs, both riser+8pin - Regular ATX motherboard - Not connected the grounds of both PSU - Both power supplies are connected to the same power outlet
The rig works perfectly well when I disconnect the power from both units, wait few seconds to discharge the caps, connect the secondary (server), wait few seconds, and then connect the main one. However after a power outage, both supplies start at the same time and the rig is unstable (boots fine, detects GPUs but hangs after I put load on them) until I manually disconnect both and repeat the procedure.
I know about Pico PSU, but I'm CPU mining as well and those mini boards are not designed for a high load. How do I solve this issue without replacing either of the units? Perhaps connecting both grounds would help, but I haven't tried that yet.
