New pc not turning on.

I have tried to short the pins with multiple configurations as in without some parts and with all and nothing occurred.

Do you have the 24 pin and 8 pin power connectors securely fitted?

[DOUGIE]

As Gus suggested, if the 8 pin and 24pin are clicked right home, then chances are you have a Standoff/ riser in the wrong place and shorting out both Motherboards.. Even a screw left under the Mobo can cause a short.
As suggested by other Techies which suggested hooking up outside the case, you have not said you tried this. Just replied with something else you tried. I strongly suggest you remove the Mobo and try outside the case and make sure you haven’t a standoff in the wrong hole. To have 2 dead Mobo’s in a row is so rare, and believe a short is happening, here.

I have the motherboard removed from the case and the 8 and 24 connected are securely fit.

Turn on the PSU and touch the power switch connector pins as per Philpower’s diagram.What happens. Any lights?

[Abull2003]

Nothing happens when I do. No lights either.

You need to take the parts, to a computer shop, and have them tested.
I have run out of clues, without having the rig in front of me.

can you provide a few shots of the current setup laid out on your desk, maybe something will be obvious?
