Need help figuring out what is fried

[Futor]

need help diagnosing how bad this problem is and what need to be replaced. Got a 3070 and updated my PSU to a 750w. When I did the install I thought I had a bad PSU so I returned it. When installing the PSU I realized my actual problem was I mixed up the cables for the power supply. got everything installed, correct cables, and power up. No screens turn on. plug screens into the motherboard. Still nothing on the monitors. Plug a monitor into my laptop and it turns on. When I did get everything powered I heard a spark and smelled that dreaded smell. I think i fired somthing. But how to I tell what is fired and what isn't.

depending on the cpu that would address the issue with no image on the screen with the motherboard.  but i am confused here, how did you mix up the cables?  Did you plug in the cpu cable into the gpu or what exacty?

I had a 550w gold EVGA PSU and replaced it with a seasonic 750w gold to make sure I had enough power. I used some of the original EVGA cables and some of the seasonic cables. I didn't realize that the cables aren't standardized. CPU wise i got a Ryzen 2600

yea cables are kinda specific to the particual power supply.  as for your cpu, that cpu does not have any intergrated graphics so it wont show a image if you plug it into your motherboard.

yeah, so everything lights up when i power on so I don't suspect the PSU. I suspect it may be the mothrboard or cpu but don't know how to tell which

well, where exactly was the "spark"? that would perhaps help to diagnose the problem.
