Pc built, but not turning on!

I have build my new pc,

https://uk.pcpartpicker.com/list/8cGxFt

It was finished about a week ago, but I have still not found a solution. The fans and motherboard light up for a millisecond, then stop. When I try again, it just does nothing.
Can anyone help?

Thanks

Try assembling it again. And why did u buy a 2666 speed ram when ur mobo only supports 2400?

Sorry, I put on the wrong ram, it's actually 2133p

That make sense. Did u built it urself and did u try disconnecting all the cables putting them back on?

I'll try that now. It maybe be because the psu is faulty (possibly), and my father is helping me. I'm 13 but have done research

I just found out the psu has a missing pin
As in on the PSU-MOBO connector there is no metal in one part. I am not sure if this is normal though

Edit: Oh, there si not wire connecting to that part

Did you used standoffs under motherboard? In correct positions?

What do they do? I put some under my MOBO

Without them the case could be shorting the mobo (which would give effect you describe). Make sure there is no standoff touching motherboard in place where there is no hole no mobo.

Thanks, I'll have a look at it
