I already sent one board back because that is what I thought too. I think I need a new power supply

They are both plugged in correctly, I have the 24 in the 24 slot and the CPU cord is in CPU power 1. Thanks for trying to help!

This is my first build and I have run into some problems... My motherboard (B450 Tomahawk Max) won't light up fans won't start nothing... I really don't know what is going on and it really sucks. I have tested the power supply which is a Corsair CX500M, which should be compatible and it works fine. But when I put it into the motherboardboard nothing happens, the fan on the power supply won't spin either. I don't know if there is a compatibility issue, so I have listed the part below. All the parts but the GPU are brand new. CPU - Ryzen 5 3600 GPU -EVGA GEFORCE RTX 2060 ultra Cooler - Wraith Cooler included with CPU Motherboard - B450 tomahawk max Ram - 2x8gb Corsair Vengeance LPX SSD - intel series 660p 512 gb IMG_1108.3gp
