Thank you for contacting us and your interest in our products! We are sorry for the late reply. Have you tested another timing mode and see if you can change the thump timeout? Can you please reset the power supply? Just in case, i have attached the latest firmware for the M4-ATX power supply. Looking forward for your reply.
