After years of following advice online i am now faced with an issue that i can't find a fix for.
I have a mining rig and recently added a second PSU and an eighth GPU . The first PSU could handle all 7 cards fine but i needed another PSU for the last card. I couldn't get it to work, it wouldn't boot to windows, but i tested unplugging all GPU's and the computer boots so the ATX PSU splitter seems to work. I reset windows and plugged in just 1 GPU and updated the drivers and i can boot to windows and the card is recognized in device manager. Everything looks right but the fans and LED don't work.
When i start the PC both fans and LED work, but after booting to windows they stop. I can't turn on the LED with Strixx software and i can't get the fans to spin with afterburner. Looking at the software everything should be in order but somethings obviously wrong.
I've spent roughly 15 hours in total now trying everything i can find online, swithing cables, testing different cards with different risers, switching the load of the PSU's but nothing seems to work.
The riser is plugged into the same PSU that powers the motherboard and the GPU is plugged into the other PSU.
Sometimes the LED flickers on for a second or two before shutting off which leads me to think it's a power issue but i'm not sure.
Any help at all is greatly appreciated since i can't even revert back to using 7 cards because the issue still remains even if i completely disconnect the new PSU.
