Question Motherboard not turning on...

So first time building and I'm having issues powering on my motherboard (b450 tomahawk max). I've plugged in all cables but nothing happens when I press the power switch. I've checked with two PSU and they both work.

When I plug the 24pin connector into the motherboard and turn on the psu I notice that this chip ( View: https://imgur.com/a/yUpxygt
) gets very very hot very quickly. I've unplugged everything from the motherboard and only tested only plugging in that 24pin connector and still the same result.

Do I have a DOA motherboard? I've tried all the basic troubleshooting methods with 1 RAM connected etc... Any help on this would be appreciated.

  • Yes I remembered to plug in the 8 pin CPU connector
  • When I plug everything in nothing boots, no lights, no fan, nothing.
  • Takes about 1 second~ for the chip to be too hot to touch (Can't be normal right?)

Is it mounted in a case ?
