[SOLVED] New built PC won't start and makes one clicking noice instead

[Crustum]

I built my first PC today but it won't turn on. The motherboard lights upp but when I click on the power button the PSU (I think) just makes a clicking noice once and nothing else happens. I've checked that the power button works and experimented with some cable connections. I don't know what to do. Can somebody help me?

Motherboard: Asus rog strix B450-F Gaming
Processor: AMD Ryzen 5 3600
PSU: Corsair RM750x
Graphics card: Gigabyte GeForce GTX 1660 SUPER OC
Case: NZXT H510
SSD: Samsung 860 QVO 1TB
RAM: Corsair 16GB (2x8GB) DDR4 3200Mhz CL16 Vengeance

I managed to solve it. I had put in the cable from the PSU to the graphics card the wrong way.
