Thanks! As soon as the new PSU and the GPU arrived I will try it out! I hope I was just too dumb and the PC will work with the GPU. ?

CPUless method.?

But the fans should go on even without a gpu or not?

First of all my English isn't the best... The problem is my PC won't boot. Whenever I press the power button the PSU clicks once and nothing happens (no fan is spinning or something else). The mainboard lights up all the time, but the lower display stays black. As a test, I had my speakers connected to the motherboard and they work without problems. Unfortunately, I can not check on the monitor if an error message is displayed because the graphics card is not there yet. During the paperclip test the PSU only clicks... I hope someone can help me. (I sent the PSU today for exchange.)
