cpu power cable correct?

legendaryjordan · 24 Feb 2015 at 18:56

computer won't boot after a new build, need urgent advice. On the 8 pin psu connector, the ports don't match up fully.

e.g. the female on my z97 is:

bottom rounded square - square - square - bottom rounded square
square - bottom rounded square - bottom rounded square - square

but the mail 4+4 pin from my psu has 6 x bottom rounded squares (sorry i don't know how else to explain them) and only 2 squares. is this why my pc won't even post?

Hi it would probably be easier for you to take some photographs. Make sure everything is seated properly and that your not trying to plug the cpu 8 pin into the gpu or the other way around

EDIT the 4+4 pin sounds more like the CPU motherboard connector but once again this will be easier to tell with photographs ( CPU pins tend to be 4+4 pin or just 4 or 8 pin ) whilst gpu cables tend to be just 8 pin or 6 + 2 pin

thank you so much for your reply.

see both pictures below. If you try to slot the male cable into the female, it doesn't look totally compatable?

Yeah sorry i was wrong! snips thinks that you have it the right way around, just make sure they are correctly stuck together and plugged in they should have a little lip on them so you can clip the two together

but some of the squares don't match up to the other squares. is that a worry?

EDIT useful diagram

So that means I'm trying to plug in a pcIe 8 pin to an eps 12v???? will that work.

EDIT: If the cable you are trying to plug into the motherboard matches the PCIe 8 pin layout on this diagram then no that wont work as i thought you need to plug the cable that is EPS-12V into the motherboard pci wont work in there

oh lord jesus christ my PSU doesn't even support this mobo???

that's what im explaining is that apparently my psu doesn't have an eps-12v? It's a CoolerMaster GX-Lite 500w

Your psu does have a EPS - 12V

From coolermaster website

M / B 24 pins x 1
CPU 4 + 4 pins x 1
PCI-e 6+2 pins x 2
SATA x 6
Peripheral 4 pins x 2
Floppy 4 pins x 1

I'm looking at my PSU and it's not there. Is there maybe an adapter I use or something?

Post a picture of all the PSU connections and we'll be able to tell you which one you need

Or just unplug everything and put each one in until the correct one comes up and fits in the hole.

There's no molex wires that would fit in that. the only other one is my 6+2 and 6+2 molex wire but that's for my gtx 970.

Thanks soooo much lads for giving me what i need here

going to look in the box i got my psu in to check if it has the EPS 12v

Thats the cable mate just make sure its the right way around :/

There's no wires coming from my PSU that support the CPU slot exactly, even if 4+4 is combined.

There must be. You sure it's not just tucked away somewhere?

im sure. the only one i have for the pcie cpu one. is there maybe a spare one in my box?

legendaryjordan · 24 Feb 2015 at 20:10

savagesam117 said:
I doubt that as it is not modular.

This your PSU?

Found this.. That's what i can gather from it anyway. By the looks of things

That's the one yeah. It doesn't have any wires connected to the PSU that have the same modules as the eps-v12 why meee

legendaryjordan · 24 Feb 2015 at 20:20

savagesam117 said:
Just post a picture.. makes life much easier

I can't but I can say for sure that there are no 8 pin connectors or 4+4 that will math the modules exactly when plugged in.

Can I ask you if there is maybe a connector I can use for this?

Edit I mean an adapter

Here is a picture of the cables that come out of your PSU...the picture is of the Coolermaster Unit you say you have

The CPU plug is the one on the furthest left

Yep that's exactly right but that cpu plug at the left when joined together amount to a pcie connector (as above) but the female connector is an eps 12v

they put out a completly different amount of power and voltage to a different set of pins....the 4+4 on the left is not the same as an 8pin PCIE connector.

If the 4+4 doesnt fit try switching the 2 blocks of 4 and make sure the peg clip is facinf the correct way for the socket, ive done it before where ive tried to plug it in and got frustrated to then discover i had 1 half of the connector facing the wrong way

Check the first picture I posted above that's the way I have it

It's the modules I'm worried about for example in my scenario a little square module is being plugged into a square with 2 rounded corners

legendaryjordan · 24 Feb 2015 at 21:01

Those ones don't fit the little modules either. Plus they're for the gpu

Your first picture was removed by admins, upload it to photobucket or something then post it again

Ok, no pictures necessary, just see below please.

1) I'm using the only wires on the PSU that has CPU wires (all the other ones are being used currently).

My motherboard slot is shaped like this:

[)[]
[][)
[][)
[)[]

My 2*4 pin is shaped like this:

[)[]
[][)
[)[)
[)[)

The question is, will my 2*4 (which makes up a pcIe I believe) be compatible with the motherboard slot posted above even though the modules are different?
