PSU connected to case fans and wont run, please HELP!!

ArmedArsenal413 · Apr 5, 2016

My 2 case fans are connected directly into my Corsair CX750m PSU via a 4 pin molex cable (case fans are also 4 pin) but when I start up my PC the fans will only receive power for a split second then turn right back off, I've tried using multiple different ports but it still wont work. Anyone else having this problem??

Why are you not using the motherboard case fan ports?

Case fans are Molex or others connectors? Do you use an adapter?

Edit:
Perhaps this can help:

maybe the connector is not meant to be connected to case fans and you're doing it wrong , even my motherboard has 3 ! case fan pins as opposed to my old motherboard which only had 2

helpstar :

the case fans where never plugged into the mother board, they where plugged into my old psu, so I assumed that they would work with the new one

jimmyEatWord :

the case fans are 4 pin molex connectors, theres no place for them to go on the motherboard

there are converters for that , that convert your 4 pin molex connector to tiny 3 pin mobo connector

ohhhhhh ok, that's good, where would I be able to get one of these converters? I'm new to building PCs and all I really know is some basic stuff that my cousin told me when he installed my PSU

have to get to bed, but I will give that a shot tomorrow, thank you for the help

to your first question : sometimes they ship them free of charge to your address specially if you recently bought your case , they did that for me ,

your second question: i think i have a vague idea of what those connectors / converters look like , i think i have a couple in the basement , i try to go there and take pictures for you and put them in this thread

Is this what you're looking for , i couldn't find my own stuff
