Question ASRock B450 Steel Legend Issues

[v0iceless]

Hello,

I am suffering over this computer build. Here are the specs:

Phanteks Eclipse P400 case
AMD 2200G 4-core processor
ASRock B450 Steel Legend motherboard
Deepcool GAMMAXX 400 CPU Cooler
Thermaltake Smart 500W Power Supply
Team T-Force Delta II RGB 8GB RAM
ADATA 960GB SSD

So, what I get is that when I plug in the computer and flip the switch on the back, the Mobo lights up, but nothing else, no CPU fan, no PS fan, no chassis fans....nothing. Power button on the case does nothing. Reset switch does nothing. It will move beyond the motherboard alone lighting up.

Things I have tried:

1. Checked manuals and verified all connections were in the correct place and seated properly. Everything is plugged in to the correct location and seated firmly.
2. Paperclip test at direction of Thermaltake Support to test the power supply. It passed.
3. Unplugged all cables from Mobo except 24-pin, 8-pin and CPU fan. No change
4. Unplugged 8-pin and CPU fan, plugged in chassis fan. No change.
5. Ordered a replacement Mobo thinking the one I got was DOA, new Mobo has same symptoms.

I'm at a loss...I guess it's possible that the new Mobo is DOA as well, but I find it unlikely. Not to mention the return process took weeks and was a hassle.

Any suggestions? Am I missing something?

No bends on the CPU and I have replaced the PSU, no difference. It's a bit maddening.

I have this exact issue. Did you find a solution?

Yes, so both motherboards I received from ASRock turned out to be DOA. I switched to ASUS ROG STRIX mobo and it worked like a charm. I also replaced the power supply for good measure, but tested both boards with both psu's. the ASUS fired up no matter what was plugged in, the ASRock wouldn't power on no matter what I tried.

I don't know if I will order another ASRock board after this experience. I'll stick with brands I'm more familiar with.
