Molex connector problem

Prathit Pannase · Mar 20, 2014

Guys I need help
I have completed building my new build but when connecting the molex connector to power supply ,I found out that out of 4 pins , 1 pin is missing.
My case nzxt phantom 530
What should I do ?
without the molex connector in built fans don't work
I have water cooling h100i.
So what should I do ?

I don't think that you need more that 2 of the four pins for the fans to work.
When fans are powered from the PSU all they get is power, sensor and control (fan) pins are not used.
Have you tried it yet or is this an assumption?

But still, with the water cooling you shouldn't have a cooling issue.

it should have four. is the wiring for 4 there?

Gee Bee · Mar 20, 2014

ok, i think you got it back to front, the H100I has three pin molex connector, and the 530 has four.
Just plug the three pin to four pin and your good to go.

I cant get what is connected with this molex... is it one of the case fan? If so fan molex connector doesn't need to have 4 pins actually only 2, black + yellow or black + red depends what voltage needs to be used 12V for yellow, 5V for red.

no the h100i has only three pins, the way op wrote it sounded like the the case only had a three pin molex. It has four.

connect three to four and your good to go.

I have connected the molex connector of h100i ,
Only problem was that the case had only 3 pin of 4 it was like || |
One missing in between , that's why I was scared.
I will go home and try to connect it to power supply and see whether it works or not.
One more question guys
My motherboard gigabyte ga-z87x-oc keeps restarting.
My monitor dint arrive yet but when I started my pc
A orange light was visible on power button of my motherboard when I pressed the power button the pc starts up but then again shuts down in 8-10 seconds then again starts up and this process keeps going on and on.
Also the hd audio cable which we plug into the motherboard is very loose.

wait until your monitor arrives and go from there.

Well it seems not of all the pins are being used anyways, as I've said before the minium of pins is obviously 2 which is power and ground pins. Depends what is the voltage it can be differend side of the molex left or right since ground is 2 pins inside, usually with black wire.

Btw look here:

I found out that there is a hdmi port on my motherboard.
When I connect it to my hd tv it says no signal ( from no connection) but even when I start up my pc there is no display.
Any idea how to make it work ?
