Hello I have a Fujitsu DPS-800GB-3 A power supply and I have a problem with starting it. I tried the method from the topic: Link . The power supply turns on (the same symptom without these jumpers) and the green LED is blinking, but it does not give + 12V (with or without load). There are + 3.3V and + 5V voltages, but the most important one, i.e. + 12V, is missing. Is there anything else to connect, or is the power supply damaged?
