Hello someone please help me I just built my first computer and when I turned it on nothing happened the fans didn’t spin no boot or anything I thought it was the power supply but it was brand new and when I did the paper clip test the fan on the power supply spun so I now am thinking it’s the motherboard but I’m not sure because people are saying that the paper clip test isn’t really good because it can still be a bad power supply even if it passed that test I’m ready to get another motherboard but I just wanna be 100% sure that that’s the problem cause I’ve already spent over a 1000 dollars on it if someone could help that would be great thanks!

Ryzen 5 2600
Rx 580
3000mhz Corsair vengeance ram
Asus b450m-a motherboard
Corsair vs series 650 watt
