asus rx 580 oc
ROG-STRIX, DUAL, AREZ-STRIX or AREZ-DUAL?

I only have a Sapphire and MSI RX 580 here an neither of those have LEDs on them.

Are you sure the LED is on the graphics card and not on the motherboard shining through or reflecting off the bottom of the graphics card? It's totally normal for a motherboard to have a standby LED, but I don't recall ever seeing a GPU with a standby LED.

Right. But you're saying the light is ON even though the PC is OFF (in standby), correct?

So, the only rail that should be live while the PC is in standby is the +5VSB. But PCIe slots don't have +5VSB:

So the only thing I can guess is that a capacitor either on the motherboard or on the graphics card itself is holding a charge even after the PC is off and it's keeping that LED lit.

Does the LED eventually turn itself off if you wait long enough?
