Cpu power canle

[WanderingFoe]

Hi. 
Im doing my first build, well test bench atm and I tried googling this but I can’t find anything helpful. I’m plugging in the cpu power cable and does it matter what side goes to motherboard or psu? One side is a 4+4 pin and the other is 8 pin. I’m using an evga z370 ftw motherboard and evga 850g3 gold psu. Sorry in advance for such a beginner question but people have been helpful here   
thanks!

The 8pin side goes to the PSU, the 4+4pin side goes to the motherboard. The reason they do this is because some motherboards only need a 4pin, so if you need to you can split the connector into a 4pin instead of a 4+4pin.

YES! It absolutely does matter. The 4+4 side is for the motherboard

The modular cables are one-way

The 4+4 side goes into your motherboard, the 8 pin side goes into your PSU.

The cables should be labled, CPU for the CPU usually the 4+4 and it may have an extra CPU power usually another 4+4 in case the board and CPU require two. The 4+4 side plugs into the board and the solid 8pin side plugs in the power supply.

As a follow-up now that you won't blow anything up, here's some more nuanced detail:

The cables usually have markings on the connectors, often saying "PSU" for the PSU-side, and things like "EPS", "CPU", "ATX", "PCIe", etc. for the device-side connector. 

 

Additionally, you can usually use some tricks to figure things out if those are unclear or not present:

• CPUs are usually a 4+4 pin on the motherboard side
• ATX/Motherboard 24-pin connectors are usually 24 or 20+4 pins on the motherboard, and a 14+10 or something like that on the PSU side
• GPU connectors are usually 8 pins on the PSU side, but often have multiple endings on the GPU side to allow it to plug into a GPU with multiple connectors using only one cable

Awesome! Really appreciate the quick responses. You all are lifesavers

They do have markings but it says MB and MB or cpu and cpu on them. Unless it’s in some kinda fine print
