Ryzen 5 3600, B550-A Pro build, no posting

So, here's the problem.

I am trying to build a new PC, but after I try to boot it, I get no output.

 

CPU: Ryzen 5 3600

Mobo: B550-A Pro

GPU: Sapphire Nitro+ RX 580 4GB (tested on another PC, works perfectly)

 

I don't know what the hell is the problem. Any help will be appreciated...

HDMI is connected on GPU port, not the mobo one

Did your fans/RGB turn on? if it didn't you probly didn't plug in the power button cable to ur mother board. Can you tell me the rest of your spec for your pc, the problem isn't awlays the mother board, CPU or the GPU. if you have another system the best thing you can do is check all parts if any of them are working.

Fans/lights are all on, Debug lights come up correctly (boot light if i don't insert bootable USB, DRAM if they are missing (tested that too), VGA light if plugged in mobo HDMI etc etc)

 

Specs:

PSU: Corsair TX 650M 80+ Gold

SSD: Samsung 970 EVO Plus

HDD: Seagate Barracuda 2TB

 

I don't know what other spect you might need, it's my first time building...

You should try taking everything apart and build it again if that doesn't work then you should ask an expert
