wouldn't push the pulse too hard , PCB isn't as good as Nirto, Windforce, Strix ( when its not on fire). though damn good for its price point
i know the higher units are superflower but stating here seasonic are oem for lower watt/range

might help, but dont think thats the issue
I think my OC average and not aggressive, set P6 at 1542 @1000mv and P7 at 1592 @1000mv , actual core clock 1500MHz and 935MHz on HBM @1000mv... max 180watt power consumption...
I will test my GPU and PSU on my brothers PC, as Danny75 advised...
I`ve ordered backup Asrock motherboard in case my is faulty... Expensive Vega 56 at the end =)))
I think one of the possibilities could be that ITX board not providing the necessary additional power through the PCIe slot. Hence why it was fine on your brother's system.
PSU maybe. Bit of a pain to test the PSU in your brother's system but if possible do it to rule it out.
Thank you for the advice, I will try it!
