First PC build - No signal on display

[LuxJosh]

I just finished building my first PC and wanted to install the OS.
As I turned it on, the fans started spinning, LED's on the motherboard light up, but no signal on the display.

Even the LED's on my keyboard light up after a while and the Caps Lock light toggles when pressing the corresponding key.
Still I don't get any signal on my display.

I already tried the following:

1. Reset the CMOS
2. Tried changing memory slots/booting with one memory card
3. Made sure all cables a plugged in correctly
4. Unplugged HDD and SSD
5. Tried different monitor and different output (HDMI / VGA)

I can't seem to find the problem, does anyone of the Pro's here know what the problem could be?

Specs:

Motherboard:
- ASUS Prime B350-Plus

CPU:
- Ryzen 5 1600

RAM:
- Corsair Vengeance DDR4 2x8GB

PSU:
- EVGA 650GQ Gold

where is your graphics card?

Do you have a GPU? Ryzen does not have a built in iGPU like Intel does. That's why it is a bit cheaper. You can get a cheap RX 460 or GeForce 1030 if you are not a gamer.

I bought a GTX 1070, it's still being shipped and I thought I couod already install the OS to save some time, so it's only the missing GPU?
