Hi there,

I've finally purchased my pc components. In regards to my power supply unit it has a 4+4 CPU connector cable and a 20+4 power connector cable.

My motherboard is ASUS P8Z77-V-LX. Now i have worked out that the 24-pin cable will connect to the EATXPWR on my motherboard.

However i need clarification for the 8-Pin EATX12V connector on my motherboard please? I assume that 4+4 CPU connector cable from my PSU connect this particular port?

Is this correct?

Thanks in advance,

Yep, that's correct.

The 8-pin CPU connector will have a matching female connection somewhere near the CPU socket which is a dead giveaway to where it fits.

Thanks all,

By the way i had another look in my manual and from the diagram i noticed i can a connect 4-pin CPU connector. Obviously i have to match up the connectors etc.

I had a look at the PSU CPU connector and from what I can see only 4 pins of the 8 match the 8-Pin EATX12V. So is it true that i don't need to connect all 8? Will it still work? I have an i7 CPU by the way.

Thanks in advance,

I've connected the 8-pin CPU cable successfully. I matched up the ports accordingly and slotted it in. Cheers.

My pc successfully turned on yay!

This is my first build so i am impressed. I was scared of blowing the CPU up so i double checked i had all the cables etc plugged before i hit the power button.

I've just installed my Windows 7 and the drivers that came with the MB.

I was slightly scared because i heard this really loud vibration noise in my pc. So i then switched the pc off, waited for few minutes, opened the pc and made sure the wires wasn't near any fans etc.

Switched the pc back on and there was a low humming noise which i had expected originally.

Now i need to continue on installing software etc.

Hey
I have the P8Z77V_PRO, the cpu connector on the mobo are 8pin but my psu has 4+4 pin and only half of it fits in. On the manual they say I can plug 8pin or just 4pin. I m worried about 2 things. Is it okay that way and can I still overclock. I have ivy bridge i7 - 3770k

I would put in 4+4 pin. It should fit in. Yes, you can overclock however you will need to make sure that you are not using the standard CPU fan that comes with the processor.
