Hello boys.
I came to ask about the function of the wires of a power source.
I know that the VGA cables are for the gpus.
But what are the SATA, PERIF and MB for?
Can I use them to feed the gpu's in some way with them?

If your cards/risers pull too many amps, your cables can overheat and pose a potential fire hazard.

But they have not answered my question, What are the cables for?

Hi bro, SATA, PERIF - > SATA and peripheral cables for HDD, or any disk drives, dvd drive etc MB -> Motherboard Remember that those SATA/Perif Cables wire could handle approximately 75watts It will easily burnt up those wire when applied to GPU that has a power of more than the watts it could handle

You can use a cable splitter for powering GPUs or Risers. But you should know few important things.
How much power your device needs How much power can handle by that splitter related to the power source that used by those splitters (SATA, 4 pins Perip, PCIe) and also another thing related to the power scheme.

A SATA max can support 75 watt and maximum you can power a riser from it as a riser itself takes 75 watt. The VGA 8 or 6 pin cable ,usually 8 pin is to be connected direclty to the GPU, a 8 pin pcie cable can give up to 200 watt in power.
From my personal experience the IT before me working in my place had made some changes to the PSU cables and it had connected three 6 pins cables meaning 3 GPU-s to the same SATA cable and gave 450 watt in power connected to a 75 watt cable. That ended in the destroying of the PSU completely , PSU was a thermaltake 700watt. Always talk with some friend of yours which is IT or works in the IT field when asking technical advice. You can PM me, while I don't promise to answer right away, you will receive your answer within a few days.

6 or 8 pin PCIE is the best choice out there. Really try to stay far away from SATA to PCIE (or anything similar) adaptors. You need to be sure your cables can stand the amperage being pulled through them.

Thank you bro. Your help is very apreciated. Do you know a good voltmeter model? When I connect everything I would like to observe what is consuming my rig

Don't do it.
Why Using those adapter cables is an extremely bad idea ? But I see many miners using adapter cables. Will it affect hardware?

Why? Is dangerous? you need to have cables with good quality if not can something went wrong. like burn the cables and damage the graphic cards

I think that the image which smoolae posted, pretty much tells you the reason why not to do it.

Invest in a good power supply with enough outputs to power everything. They have fallen in price again. Power is the blood of your mining process. And investing in good power supplies is for your safety.

maximum of gpus per sata cable of 3 to 4 connections is 2 and no more than 2.
