Solved Computer I built won’t turn on for first time, only displays yellow/orange light on Mobo when power switch on PSU flipped.

[WhipcatMetre]

Recently finished my first PC build, and have got it all together and built. However the computer won’t turn on when the power button is pressed, no response at all from fans or anything. The only sign of life I get is a yellow/orange light around the gpu slots and lower left hand side of the motherboard when I turn the PSU switch on when it is connected to power. I have tried testing it with each different ram stick as well as with and without the gpu, each time no change, same response with the light and nothing else. I have checked all cables routing from PSU to various modules and from the case into the motherboard (usbs, power, reset etc) and all appears to be correctly connected. I have tested the PSU using a paper clip on the 24 pin cable and it works fine, and have tested it with the case’s fans and it works fine too, making the front and back fans on the case light up and run as well as making the cpu fan run, and when connected to the HDD using the paper clip test method the HDD can be heard running as well. Thoroughly stumped here, any help would be much appreciated - thanks in advance . My PC Parts are as follows:

Pull everything out of the case and rebuild the PC on a non conductive surface, eg cardboard, and try that.
