which end of the power cable to use on the motherboard?

[xxcrimsonspiritsxx]

Okay so I have this cable that connects CPU power to the PSU, one end is 8 pins, the other is two 4 pins...

Question is: does it matter which end goes to the motherboard and which goes to PSU?

My manual has no information on that sadly


Thank you for your time

mane and model of psu same for motherboard .

Sounds like you have a modular PSU. If so the 8 pin goes to the PSU, the (2) 4 pins go to the motherboard (sometimes you need (1) 4 pin and sometimes you need both which is why they give you (2)). Not sure if you can even put them the other way.
But, as other poster said, we need the model of PSU and Motherboard to tell you for sure.

Thank you both for attempting to help

The PSU is EVGA 750W fully modular as you said

The motherboard is an Asus ROG Formula X

use the 8 pins cable mark cpu in the psu cpu slot 1 then use the other end to the motherboard of the same cable since it also need a 8 pins one to work .

So the 8 pin goes into the CPU1 on the PSU

And the 4+4 goes on the motherboard's 8 pin slot for the CPU ?


Is that correct?

QQ: is it true that one 4 pin is needed for the mb to work, while the 8 pin is used to be able to OC?

no the board need the 8 pins to work that is how she was made .

Some mainboards (X99/299, X399 for example) need a pair of 4-pin CPU PWR inputs...; most motherboards don't need or use the other input...

Argh.. Okay sorry if I sound dumb but I'm not sure I follow


The 8 pin (not 4+4) goes into the motherboard
And the 4+4 (not the whole 8 pin one) goes into the PSU CPU1 ..... Correct?

 

[scout_03]

the full 8 pins to cpu and the 4x4 in the motherboard that how you should connect them .

I think you meant to say the full 8 pins to the PSU, not the cpu.

Alright that seems to be the right way


Would appreciate it if you could edit the "CPU" to "PSU" so that others could benefit from your answer as well


Thank you very much for your time

yes was a typing error 8 pins psu and 2x4 to board .
