PSU 'molex' question.

There's this crazy molex type dilly coming out of my PSU. It has 2 yellow, and 2 black wires, and the end looks just like a molex, except it's square. Looks sorta' like:

'U' being the thing that locks it into whatever it's supposed to be locked into. (It's supposed to be in the center....doh)

Anyways, my question is this: Can I put anything (like, a fan, for instance) into it? Or is it 'special'?
 
thats for your motherboard, if you have a Pentium 4. so unless you want to mod something that usualy uses yellow as its hot feed to that and risk messing something up (i dont know ive never done it, it may be ok) then id just tuck it up by the psu
 
Its the same type of wire used for the yellow molex connectors so... well in my friends system we just soldered those wires onto a molex connector for extra length. works fine :).
 
It sounds like an AUX for your motherboard. Mine is shaped that way. What PSU do you have? You can probably go to the manufacturer's site and check out an online manual. They are usually in PDF form.
 
Are you sure that's not the 3V connector? With newer processors, that extra juice is required for normal operation. If your motherboard has a spot for it right next to the CPU, then that's what it is.

If not, I also speculate that it's an old AUX connector. Bloody micro-ATX motherboards...

No, it's definitely the ATX12V connector used by many new motherboards. It provides two addtional 12 volt lines for safer and increased current delivery if necessary. The connector can be clipped (not recommended) or tucked away if the motherboard doesn't need it.

What he said. I'm honestly surprised that other people here did not know what this thing was.

You can use it for fans if you don't need it for your mainboard. Otherwise, I'd use it for what it was designed for.

AMD and Intel motherboards are using these now.
 
The reason I ask, is because right now it's hidden nicely behind my mobo tray, and I'd like to use it for a fan, however I wanted to make sure all would be fine using it for that.
 
leave it alone, almost every new motherboard being used today requires it (and if you don't plug it in, your system will be unstable)

Unstable? :confused: I haven't ever had it plugged in, and my system is stable. :confused:
 
Some boards will work without it, but your overclocking results will suffer. You also might melt your ATX connector onto the mainboard.
 
If your motherboard has the connector for it, then you will need to use it there. If it doesn't have the connector, then you can use it for something like a fan. I do not suggest cutting it at all in case you upgrade and the board you get needs that connector.
