Hi, I've got an issue with my new build, any help/guidance would be appreciated:

The issue after installing everything and then plugging in the power cable, the light on the power switch and hdd light come on and stay on but pressing the power switch does nothing, no life from the fans. I've tried resetting everything (I think correctly) but still no go :(


This is the hardware I've got:

Gigabyte GA-Z170N-WIFI Intel Z170 (Socket 1151) DDR4 Mini ITX motherboard
Corsair Vengeance LPX Black 8GB (1x8GB) DDR4 2400mhz 1.2v
Intel Core i5 6400 2.7GHz Socket 1151
be quiet! System Power 7 450w '80 Plus Silver' PSU
Corsair Hydro Series H75 Liquid CPU Cooler
Fractel Design Core 500 case

no graphics card plugged in yet
 
Thanks, I'll double check the headers are in correctly. It's not really clear on the power/reset/HDD led headers which way round is positive and negative, there is a down arrow on the back, does that mean anything?

The 12v cable is plugged as well as the 24 pin connector.

The lights are definetly coming on as soon as the power cable is plugged in, before the power button is pressed.
 
The arrow does indicate the positive, so I've got the headers in the right place according to the manual.

I've ordered another power supply, if that doesn't work then I'll see about returning the motherboard.

Thanks for all your help and advice.
 
I've tried putting the components outside of the case and using a screwdriver to power on but still no luck.

The 4pin ATX cable is connected
