Hello,
I have a 1600w titanium PSU which I've been using for a mining rig. I added a new GPU recently and did some rewiring. The PSU would try to turn on, I see some LEDs flash on components and the fan is about to spin, but it shuts off right after. I rewired everything again (GPUs, risers, etc), tried again and it won't turn on at all (No LEDs flashing and I don't even hear a relay sound). I unplugged everything and plugged the tester, same behavior. Is there anything I can do to troubleshoot it, like a fuse check or similar?
