Question Asus B450F Gaming starts but then nothing happens

[Galaf]

Hi,

I just bought a new system and built it.

In order to test, I plugged it in.
Lights turn on on the motherboard and GPU and when I press the power button of my case, my CPU fan does turn on but that's about it.

No Q-LED lights whatsoever, no beep, nothing.

Does any of you know of a way to troubleshoot this? Is there any probable culprit?

Thanks for your help!

And, in addition to the above suggestion by @egda23 , update your post to include full system hardware specs and OS information.

CPU: AMD CPU Ryzen 7 2700X with Wraith Prism cooler

HDD: Seagate Baracuda 2Tb
PSU: Antec NE75G
Case: Antec DP501

OS will be Windows 10.

In the end, I was missing the 8 pin connector.
Other things that happened to me during install was:

• I thought you could put DDR4 any way you needed to but they only work in one correct orientation so if the DRAM led lights up, try setting them up the over way around.
• Making a Windows USB boot key without a Windows environment around is real Hell (I only had Mac OS around me). If you need some help, feel free to ask.
