Computer doesn’t turn on at all after connecting case wires

[aggideladida]

Hello, I am currently in the midst of building a computer for the first time and after finally getting it to boot up and install Windows, I decided to put in the wires for the Phanteks LED strip and fans that came with the P400S case I bought.

I connected a 12v wire with a SATA PSU wire and connected the LED strip with the case front panel on one side and a 4 pin wire with USB headers on the motherboard.

Then I connected the fan wires with the fan headers on the motherboard. After that, I turned the PC on again and a blue flash appeared for a second and the PC shutoff. I have no idea what exactly happened and I am unable to turn on the PC at all.

I also tried turning the PSU on and off and have noticed the white lights that are always lit
on the GPU near the PCIe ports are not lit.

Anyone have any idea what happened and how to fix this?

Also some PC specs if it helps:

EVGA Supernova G3 650W PSU
ASUS GTX 1070 8GB ROG Strix
Gigabyte Z87N WiFi
i5 4690k

Did you check pinout with motherboard manual.

Their front pannel connector with their own pins of each buttons and switches .


If all works fine then try to reinstall ram in different ports

The front panel plugs were in the correct spot already since it booted up before, but I did replug it right now just to be sure. Also tried relocating the RAM in a bunch of different combinations and the PC won't turn on still.
