Hi, I bought a prebuild PC a few days ago and I noticed 2 of the PCI-E cables on EVGA RTX 3080 are not connected to anything. Are they necessary? The PSU is Fractal Design Ion+ 760W Platinum.
Also another thing...the GPU is not recognized by any software such as Aura Sync so I can't color match the RGB with the rest.
And a third Question unrelated to the GPU...when I turn off the PC and flip the PSU switch off, there are still some lights blinking inside of the PC. How come? Where are they getting power from?
