so i was really exited to finally build my new pc. i plugged in everything in the right place and i even checked several times.so when i pressed start, all that spun up for a sec was the psu fan and thats it. nothing happend. it didnt turn on. so i wanted to check if the psu actually works so i turned it on without anything plugged in and it worked just fine. so i plugged everything back in and tried again and again and still no boot up. and then all the sudden the psu starts to smoke. i dont even know what to think now. i need some help. is the psu broken or something else???
