My custom pc is not starting!

[AlleLalle]

Im done with building my first pc, but it wont start. The motherboard led's light up, but when I press the power button nothing happens. I dont know if the power supply fan even starts. Please help ;c

Thanks I rebuilt it and I see the pc wont start because when I plug the molex cabel in. What does it do, and it goes from the chassi it self. I got a 6 pin connector from the powersupply and to a 4 pin fan connector on the motherboard, and the one from the chassi goes right in there.

Read the manual for that,it should tell=blue light.

it's probaby from the built in fancontroller.

and it goes from the chassi it self. I got a 6 pin connector from the powersupply and to a 4 pin fan connector on the motherboard, and the one from the chassi goes right in there.

You really lost me here,6pin to 4pin to .... what?

The molex from the chassis goes into one from the psu.
A 6pin to 4pin?

 

[AlleLalle]

I mean, the molex from chassi needs something to put into, so there is one cable that goes into the powersupply with a 6 pin connector. The other end is to the motherboard.

and when I just plug the power supply pins in, it starts but no case fan starts

Like i said,attach this directly to one matching from the psu.

so there is one cable that goes into the powersupply with a 6 pin connector. The other end is to the motherboard.

This one is probably for the gpu=pcie connector.
What goes to the motherboard? How many pins?

Read again,

a 6 pin connector from the powersupply and to a 4 pin fan connector

You don't connect a 6pin to a fan connector.
What do you mean by a "fan connector"?

 

[AlleLalle]

I know see I just needed to connect one to the power supply but now it starts but no case fans starts

 

[AlleLalle]

Fan connector, the 4 pin ones on the motherboard

 

[Vic 40]

Nothing from the psu should go directly to a fan connector!

 

[AlleLalle]

THANKS THATS ALL NOW IT WORKS! THANKS SO MUCH!

 

[Vic 40]

You're welcome.😀

Glad we found the problem.

Actually, that's not true. On occasion some builds or builders I should say, they do install fans and/or pumps with their connectors plugged directly to the PSU without going through the board so they will have full unregulated voltage. It's quite common in fact and is the reason the sell adapters for doing so. I realize that was not the case in this situation and glad you solved the OP issue. Cheers to Vic 40 and the OP.

This still means no cables from the psu go directly onto the motherboard,they connect directly to the pump or fan,that's different.
The o.p. is talking about a fanconnector/header on the motherboard,not on a fan.

 

[Darkbreeze]

Oh crap. Yeah, PSU definitely doesn't connect to the fan headers. Heh. Sorry, I misunderstood that part.
