Tb250-BTC PRO problems

[J10]

I have a problem with this motherboard. I connected 4 GPUs and it started, but then I added two more GPUs and now it doesn’t start at all, no power at all. Did I burn it?
It doesn’t start at all, with or without any GPUs. I tried clearing CMOS but nothing. I have a TB250-BTC + running the same 6 GPUs without a problem.

All RX 570’s, it seems like there is no power going into the board, but the power supply is good, 1200W Corsair.

Any suggestions?

First of all, how you try to clear CMOS? trough CMOS jumper? or battery?. Most effective to clear CMOS is unplugging the CMOS battery.Try to unplug and plug again your RAM, don't plug additional GPUs power. Make sure your PSU is working good.
