Newly built PC won't start (not even fans turning)

Patxher999

So I just built my new PC: Ryzen 5 3600 MSI Rx 5700 Asrock b450m Steel Legend Corsair Vengeance 2x8gb

Anyways, I got it nicely built, plug it in and turn on the PSU. The lights come on on the motherboard, but the power switch does absolutely nothing, no fans turning, nothing! I also tried shorting the power button pins on the mobo, but got the same result.

I've tried unplugging everything and plugging them back in (except GPU and CPU), and I've tried different combinations of the two RAM sticks, but no result.

The motherboard needs the right BIOS version for the CPU, but the box came with a "Ryzen 3000 ready" sticker on it, so that should be fine. But I'm wondering if perhaps the BIOS might not have been updated? Would this cause the PC to not even attempt to turn on?

I have tried stripping it back to just PSU, mobo, CPU and heatsink, again with no luck.

I have also tried using a spare PSU and both PSUs passed the paperclip test.

I have also tried clearing the CMOS.

Please help, I'm open to any suggestions!

Thanks Happy

Most likely a power supply issue, make sure everything is properly seated.

it could be that he is using the intel layout on the nzxt h500 instead of plugging in the amd adapter
