New Build Starting Then Instantly Shutting Back Down

[nwolf1010]

i built a pc for a friend recently and everything went smoothly when i put it together then when i went to check if it would post it turned on for a split second then turned itself of instantly after, i have tried the following so far.

paperclip method to test the PSU

Installing a new PSU i know to work

starting it with just one of the ram sticks (tried with both)

made sure everything was connected and put in all of the way

replaced the BIOS battery

unplugged everything from the MOBO that is not necessary

Tried a different outlet

Im out of ideas guys, im thinking it must be the MOBO at this point, the only other thing it could be is the CPU and i dont think it would cause a problem like this anyway.

here is the full build

You will need at least a 550w PSU to run that system. GTX 1080 minimum PSU requirement are 550w. Also don't by a crap PSU like that. Spend a few extra bucks for a proper quality one.

the total tdp of the system is 341 watts so that should not be the problem. on top of that if you actually read my post i had tried plugging in only the bare minimum to my pc (meaning i removed the GPU if you couldn't understand that) and it STILL dident boot properly.

im sorry if i was rude but you dident seem to even full read my post before posting your response

 

[Kasper Jorgensen]

Apologies accepted.

I did read, but many low quality PSU's cannot deliver advertised wattage. Also, by your description of the problem in hand is a typical PSU problem. Obviously it could also be your mobo but very unlikely your cpu as that will just cause a black screen.

Was the mobo installed in the case for all these tests? If so try out of the case...
it could as simple as a short...good luck though.

Also I have to ask, you did plugin all power connectors and specially the 12v cpu power connector located near the cpu socket right?
