help with new build

[Alex93]

i have a new pc build its not working when i first turned it on there was no pictures but everything was on now there nothing turning on i have unplugged replugged everything multiple times still nothing ive been messing with it for hours the manuals that came with it are useless also unsure about this 4 pin connector coming off the motherboard connector 

 

yes the ram is in the right spot i assume its a connector problem when i plug it in there is a white flash then nothing

well thats a mess!

 

it looks like you have the 24pin cable from the psu to the motherboard the wrong way around, the solid 24 pin goes into the motherboard the other end that is split into 2 connectors goes into the psu...lets hope you have not fried anyting?

[aledsav1]

I would remove all cables again *carefully and re do the cabling, making 100% certain you are using the right cables and the right ends of them are in the right parts -motherboard-psu, you see the last photo, that spereate cable on the inside of the case going to the 24 pin is wrong, that goes into the motherboard end (same as the rest of the cable for the 24 pin)

Start by checking that all cables are fully inserted. Couple of your pictures show cables that aren't plugged in all the way.

Does this white flash happen everytime you try or only the first time

If its only the first i suspect something may have shorted

anytime i flick the psu switch

[aledsav1]

in the last photo of the 24 pin cable going to the motherboard there is the main part of the cable behind the case but there is a cable (4 wires looks like) inside the case, that should not be happening it is all part of the same cabling, the main 24pin motherboard cable must be plugged in wrong, I have never seen it able to be seperate like that before

 

the 24 pin connector that goes into the motherboard 24pin header is solid block not 2 seperate parts

I know this is going to be a pain, But can you take everything out of the case and assemble it externally to check if you get a boot that way.

That PSU in particular has an extra 4 Sense Pins that go into the PSU.

took out the old gpu no more flash but still not powering on

[aledsav1]

just looked at the siverstone psu and it does show the seperate 24pn block? so maybe its right

thats what i thought as its the only spot it fits

[aledsav1]

so that is the 8 pin for the top left of the motherboard...you have that in yes not the one that has 6 pin and 2 pin seperate

[aledsav1]

and that is the motherboard 24 pin..you have that end in the motherboard yes?  look the wires are all connected further down from the block, so why is your seperate and running inside the case when the rest is behind the case??

[aledsav1]

I would remove everything from the case and build outside, just getting the wires right and then test..as from photos its all looking a bit confusing with that 24 pin having a seperate wire running to it

good thinking i got picture this time now i need to put it back together 

[Alex93]

pulled it all apart like suggested and managed to find a cable mentioned all looks to work now i must of gotten the cables mixed up once i put back together ill be back 

[aledsav1]

brilliant...be carefull you don't mix the cables again when you rebuild..just take your time

[Alex93]

pulled it all apart it works put it back together it wont work 

[Alex93]

had to plug and play with the cables it’s decided it wants to work

[aledsav1]

so obviously theres a connection problem with the cables, but seems you found the issue, just make sure all cables a firmly clipped in both psu and motherboard ends
