GPU's fans and logo light wont turn on

[eblive126]

My whole computer will power on except for the GPU's fans and logo light. I first thought it was a power issue so I bought a new power supply. I installed it and the same problem occurred.
Specs:

GPU - RX-480
CPU - Intel i5-6400
Power supply - Corsair 650W
Old power supply - EVGA 400W

Did you install the driver? Does the GPU work after driver installation?

I've installed the right drivers to the GPU and it still did not work after that

The fans and the light log are connect on the gpu board with 4-pin pwm cable. You may want to have a look at this connection which is revealed if you remove gpu cover

All the power connectors are plugged in and there are no blown capacitors

You have your monitor connected to the GPU and not your motherboard?

I have a multi-GPU mining rig with 6x Sapphire RX 570/580 Nitro+ conencted via risers and a lot of times half or more of them don't light up until the mining program starts. I thought it was because I was using the iGPU for my monitor connection.

I'm sure that i have my HDMI cord plugged into the GPU

Is it recognized in Windows Device Manager? What about AMD Radeon Settings?

It's recognized in Device Manager and in WattMan the fan speeds are stuck under 100 RPM

What's the make and model of the RX 480? Did you buy it new? It could be DOA.
