Gigabyte B450 Tomahawk Max with Ryzen 5 3600 and GeForce 1650 HyperX Predator 16GB PCIe 650W power supply worked until yesterday. Power failure occurred. I took it out of its case, removed all components, attempted to connect the power pins, but nothing happened. I bridged the pins on the PSU, the fan began spinning. I tried using a 600W PSU just in case a connector failed, connected the power on the motherboard, but still nothing. Then I switched to a 650W PSU; when I bridged the pins on the motherboard, the PSU fan started moving again, though it stopped after a click. I saw someone on YouTube using the same motherboard and bridging the pins without CPU, GPU, or RAM—then the PSU fan spun. Anyone knows what’s wrong?
