Hello,

In my desktop Dell Vostro 3668, there's an outlet of 6 pins on the motherboard for connecting a SATA power cable. The power cable includes 5-6 wires and has at its other end a SATA male plug. I want to connect the SATA cable to a SSD.

My question:
If I connect the power SATA cable having the 5-6 wires through another power SATA cable having just 4 wires, to the SSD, how this might affect the condition and operation of the SSD ?? I mean to the reduction in the wires -- from 5 or 6 to 4. How this reduction might affect the SSD regarding its durability, operation and efficiency ??

From the motherboard, you get SATA data, not power.

Pictures of what you're talking about would help here.
You are not correct in my case. I have a 6 pin power outlet for SATA on the motherboard. It is also written near that outlet SATA_PWR2. There's even a 6 pin power cable with SATA connection in the market for that outlet . If it was allowed in this forum, I would upload 2 photos of both the motherboard 6 pin outlet and the power cable.

Then that should work.

What cables come off your PSU?
Right now I can't say what cables come off the PSU. But I was asking in my thread what would happen if I take the SATA power cable like in the picture, which is with 5 or 6 wires, and connect to it old SATA cable with 4 wires and then connect that old SATA cable (with the 4 wires) to a SSD ?? How this transit from 5 or 6 wires to 4 wires, would affect the SSD ??

I need to this because I don't find where I live a female power SATA cable with a 6-pin connection. The SSD has a male SATA inlet and so it requires a female SATA plug on the cable.

I have no experience with that particular motherboard or 6-pin connection.
But, if it is labeled SATA Power, then it should work with its appropriate cable. I would NOT use some random cable...but only that which came with that board or PC.

Please look and see what specific cables come out of the PSU.

What can happen?
From that 6 pin port on the motherboard, using some random cable, connected to a typical SATA drive...

...You let the magic smoke out and your drive is dead dead dead.

That is a non-standard SATA power connection, and a non-standard cable.
 
Correct me if I'm wrong, but the OP's adapter cable appears to connect a SATA power output from the PSU to the power input for the graphics card on the motherboard.

No, the power output in my desktop is on the motherboard, with a 6-pin outlet. But you are correct -- the SATA cable in my picture is male and so I think it's for graphic card. But I need a SATA female for SSD because on SSDs the input connector is male. But I don't find where I live any female SATA cable with a 6-pin input. That's why I am trying now various ways to match the available SATA male cable to my SSD, by using other old SATA female cables. That is the reason I asked the questions at the beginning of this thread.
