Difficulties powering my system

[mrroudeleiw]

Hello,

Yesterday I build my new System and I have a quiet weired Problem.

When I shut down the System, sometimes (like every 2-3 time), the System doesn't have power anymore and won't start again. The only way to fix it, is to unplug replug sometimes.

I can see if the System has power because my graphics card (Zotac GTX 1080 AMP) has a light that indicates if the System has power.

Any idea where the Problem could be?

Specs:

Core i7 7700k

MSI Gaming Pro Carbon Z270

ZOTAC GTX 1080

BeQuiet Straight Power 600

check all connections, did you try to overclock your cpu?

Just rechecked the connections, every fine. No overclock
