Changed my case and doesn’t turn on

FelixSutton

Me and my friend swapped PSU and I plugged everything in but the computer only boots on for a second and turns off. The PCIE is green and the sb power is red.when I press the on button I can hear the fan turn on and the lights turn on but only for a split second.

You don't have the CPU power connector plugged in. Top left side of the motherboard.

What does the cable look like that? Because all of the cords with the psu don’t look like it will fit

It will be split into two groups of 4 pins.

Will look like the top left image. The CPU 4+4 connector.

Image result for cpu connector

You are missing this in the top-left corner, should work fine after you plug it. No wonder you got lost in the cabling with such management.
