Build won't startup

[ILogiq]

I'm in a huge problem.
Yesterday I bought my ram.
And the day before that my new case arrived.
And more components would come next month.
So I thought.l that I should just change everything from my old case to the new one and change the ram.
So I would be ready for next month.

Well. I felt like the building process went pretty smooth but that changed rather quickly.

As i finished building I noticed one of my psu cables was too short. (4p) so I decided to change the psu's place to see if everything would run smooth.

Well to my surprise, the computer did t even startup. It was as if it wasn't connected to the electricity.

So after panicking, I decided to change everything back into the old case.

After everything was setup I tried to start the computer up. And guess what. It still didn't work. I don't understand whats happening. Everything is plugged in.

I even tried with the old ram. But no difference.

Any help would be appreciated.

Double check the small 2 and 3 wire connections from the case to the motherboard and make sure they are connected properly for PWR (Powe) and RSET (Reset). Make sure the power supply rocker switch is set to On. You need to find the motherboards manual to make sure your connections are correct.

I'm pretty sure everything is plugged in.
I already tried plugging out and in and no change.
