Hi so I am putting together a computer and I install all the parts I have double and tripple checked all plug ins and I have got everything installed correctly but my pc will not boot it wont go into bios or anything. I am worried it might be my power supply as the motherboard has 3 4pin psu connections in the top left and my power supply only has 2 4pin connectors. other than that I am not sure what it would be. I know my mother board it getting power because I can get all my case fans to power up and spin and their led's come on but other than that it wont do anything. Also it will stay on for like 30 seconds then reset. I have made sure everything was put in all the way so no connections were half in. here is my full part list (I have a temporary gpu so its not included in the part list as im only using it until I get a new one and I dont feel as if its relevant because I know it works because its been in another pc for months now)
