Where does my case fan plug into? (Also help with the other tiny case plugs)

[Sebubble]

I watched several videos on how to build but all the case fans seemed to have the same plug. Mine doesn't. It's quite big and has two very big pins in it with what looks like two missing. I can provide a picture if no one knows what I'm on about. There doesn't seem to be any way to plug it into the motherboard.

Also I've followed steps on plugging the smaller plugs in (P+ P- etc). I looked inside my old PC and copied the order. That's okay isn't it? Does it matter which way they face?

There's only 2 types of fan plugs, the smaller pwm or the bigger molex. Molex fans only have 2. The fan won't be switching which pin is used so the others are useless. They could not be at full speed if they are wired to the 5v rather than the 12v wire. You can switch the pin actually and I've done it before. Some of my older ones that are molex have a speed switch yet are still 2 pin. Resistors are great aren't they.

Manual page 1-18 for front panel pinout.

That's molex, it goes into the psu.

The pinout for the mobo front panel header may not be the same as your old pc. Do not turn on the pc without checking that mobo manual so you don't short and kill things. What way they face doesn't matter.

molex has 4 pins usually, to be sure post the picture

those fans on molex will work at full speed because they work directly without the mainboard control, so no speed management at all, not desirable if you do care about noise

The manual only shows one row of plugs, the others being hidden behind so I couldn't see which ones they were. I will check again but is there any diagram that shows the order of those plugs on a ASUS LGA 1151 STRIX Z270E GAMING Intel Z270 ATX Motherboard?

Thanks for the help with case fan. I've looked it up and the 2 pins is normal. I just hope the wire is long enough to reach the PSU now.

MERGED QUESTION
Question from Sebubble : "Where does the Molex connector plug into the PSU?"

I have a Molex plug for the case fans on my build and I believe I saw a connector in the PSU box but I don't know which plug to put it in. PERIF?

PERIF=Molex

Yes, the "PERIF" cables in the PSU are the 4-pin Molex connectors where you can plug your Molex case fans.

The cables connectors should look like this:

Question from Sebubble : "24 pin cable in the wrong way around?"

This may seem like a stupid question but I want to make sure I've done everything right before I attempt to turn it on. I had a cable with a load of pins in it that said MOBO so I know it's the motherboard cable for the PSU. However one end has all the pins fixed together and the other end has two seperate sections. I've put the fixed end into the motherboard and the two piece into the PSU.

PSU is EVGA 220-G3-0650-Y3 SuperNOVA 650 W G3 80+ Gold SLI/Crossfire Fully Modular PC Power Supply Unit

Motherboard is ASUS LGA 1151 STRIX Z270E GAMING Intel Z270 ATX

It only fits in one way. I'm just going to merge all your cabling issues threads.

Question from Sebubble : "Where does CPU cable go?"

I'm just finishing up with my build (mainly cable whereabouts) and I want to make sure I've got everything correct. I got a cable with my PSU that says 'CPU' on it... which I assume I need to use. I have a few other cables which I think I'm not supposed to use (extra VGA cables etc).

I've got the ASUS LGA 1151 STRIX Z270E GAMING Intel Z270 ATX Motherboard and I've plugged the CPU cable into the top left. It was actually two 4 pin plugs.

I hope this is correct. If I have anything wrong, it won't explode will it?

You're good to go.

DOes your PSU already have one small cable connected to MB labled CPU or AUX CPU? (you won't need a 2nd for Z270)

I will have to go back into the garage and check tomorrow but I believe the only other cable connecting the motherboard and PSU is the 24 pin plug.

Thank you! Apologies for the flood. I'm never sure I'm posting in the right section. Sorry! Thanks again for all your help.

Question from Sebubble : "VGA cable in the wrong way around?"

This may seem like a stupid question but I want to make sure I've done everything right before I attempt to turn it on. I have used one of the VGA cables that came with the PSU to connect my video card. GTX 1070 O8G. The cable has one end that's 8 pins fixed together and the other end has 6 pins and then a seperate 2 pins. I have plugged the fixed end into the PSU and the 6 and 2 into the GPU. Is this correct?

That is right, however, if your PSU does not have pci-e cables included, it is not up to the task of powering your PC with that expensive card. Id replace your PSU ASAP, like dont wait.

Yes. That is the correct way to place it.

No cables came marked as PCI-E, however it came with two VGA cables and I guess they're the same thing?

It's not that it's in the wrong section, it's the same issue that can really just go together: cabling help.
