Newbie question in connecting a PSU

post #1 of 13
Thread Starter 
Hi guys.

I just got my Enermax Liberty 400W. I know this is quite newbish, but It seems that I have a 4pin plug for the CPU, and also a special 6pin plug for the PCI-E.

I can't seem to find a special CPU 4pin connector in my motherboard. There is however a 4pin connector called "ATX_12V". Do I need to plug the 4pin CPU plug into that connector?

About the PCI-E plug. Where do I plug it? do I even need to plug it?

The 4 Pin Connector is for your floppy drive I think you will find and you only need to use the PCI-E connector if your PCI-E graphics card needs extra power - which the 7600GS doesn't

I don't think he's talking about the floppy connector.



I think he means that, in which case there should be a connecter on the mobo. If there isn't, you may not need to plug it in.

EDIT: http://www.links.co.jp/html/press2/image/i945pg-rh.jpg Judging by that picture, there is a cap on the 4 pin part on the mobo power connector that you have to pop out.

Thank you.

the 4 pin cpu cable is for the CPU according to the Liberty 400W manual.
Did you mean the 4 pin connector on the motherboard itself? labeled ATX_12V?
Are you sure about this because I think this is meant for the CPU.

From Gigabyte's manual: "The ATX_12V power connector mainly supplies power to the CPU. if the ATX_12V power connector is not connected, the system will not start".

Muftobration: I didn't mean that. that the 24pin atx connector. I have that connected already. I have an additional 4pin cablethat is meant for the CPU.

Yes, the 4pin which is quadratic is also called the ATX12V plug, so plug it in!

Yes. That will provide the psu power through that 4 pin mobo plug. The CPU gets power from the mobo itself. If you want, you can try booting without the 4 pin plugged in. If it doesn't boot, plug it in and see if it does. I'm pretty sure you need it, but they did cover up the 4 pin plug on the mobo, probably for a reason.

Edit: I see what you're saying. You have the 24 plugged in and still have an extra. You don't have to plug in the extra one, just the regular 24 pin.

You WILL have to plug it in for it to work. Try without it plugged in, if it boots, you should be OK, and if it doesn't, plug it in.

Thanks again guys

I intend to overclock my CPU quite a bit. It will consume a lot of my power. In that case should I just have it connected anyway? can it harm anything?

I also have a special SATA power plug, instead of the 4pin molex. Where do I plug it?
The last PSU I had simply had a molex and a 24 pin ATX cable. that 's it!

The SATA power connector is for if you have SATA devices (like SATA hard drives). You don't need it if you have no SATA devices.

If you have no place to plug in the extra 4 pin connector, then you have no choice other than leaving it out. If it was built to only have the original 24 pin connector, then overclocking should not require the extra 4 pin. You will get plenty of power from the 24 pin anyway.

Edit: Do you mean that it has SATA, but NOT any molex?

I have a sata HD. I used a 4pin molex to fire it up before.

I don't think you understand me correctly with the cpu 4pin plug. First of all, I do have a 24pin ATX motherboard. So all the 24pins(the 20+ small 4 pin plug) are connected. Besides that I have an extra cable going from the PSU which is designed for giving power to the CPU only. I also have a similar connector on the motherboard itself, called "ATX_12v". According to the motherboard's manual it is meant for the CPU also. so I guess I should have this cpu power cable connected into this 4pin connector right?
