[SOLVED] Molex fans to 4 pin won`t start, pls help :)

[Adi Bulz]

Hello, i just build my first pc, i have a problem with the fans. My case comes with 6 fans, all of them use molex. My psu has a molex to 4 pin adapter, 2 molex and 1 4 pin. If i plug the fans to it, without using the 4 pin everything is good, 3 for each molex from the psu. If i connect the 4 pin to the mobo my pc wont start. I cant connect them to the mobo? Thank you very much for your help!

What brand name and model is your mobo?
Does this case have a multi-port fan header on it? What brand name/model is this case also?

My mobbo is Gigabyte b450m ds3h, my case is spacer h3x@ and it dosent have a multi port fan header.

Can you show any photos of your adapters/ how you're connecting them?
What are you calling 4pin? Floppy power connector? Do not connect that to motherboard!

Yep, i think thats it. Its a cable with 2 molex and one of these. It`s my first build, sorry.

You are connecting a power cable to the fan header on the motherboard it seems. That is why it' snot starting, you are lucky you did not fry your system.
