So as the title reads, i tested my new and first build PC outside the case, breadboarding, everything worked great pc would stay on and function.
But when i installed everything in the case, it shuts off after 2 beeps which is like 5-10 seconds.
Please help i am very desperate and have researched everywhere.
I have done this twice and it is the same resolute.
Yes all the standoffs are installed correctly.

Motherboard- Asus B85M-G
Processor-i5 4670k
RAM-Corsair Vengeance 8gb DDR3
PSU-Corsair CS550M
Harddrive-WD 1TB
