GPU PCIe 6+2 pin connectors

[Momkai]

Hi,

 

Today I will be receiving my new system with a 3080. 

 

The only thing i didn't order is a PSU, because I have a almost new one laying around (850W). The only thing i forgot is that the 3080 needs 3 x 8 pins to power it. The PSU I had left has only 1 cable with 2 x 6+2 pin. 

 

Fast forward, i ordered a 6+2 from amazon, but the cable looks somewhat thinner. See attachments. The numbers on the cable are almost matching.

 

Would you connect it?

It definitely looks a bit thinner and sketchier.

But there's a more important question:

Did you make sure that it has the same pin-out as your power supply?

It has the same pin-out as my own one. I've added a picture.

It's 16AWG vs 18AWG. Most PSU's have 18AWG cables, yours had thicker ones because it's a two in one. It would not make a difference in terms of amps, BUT I would be worried about pinout. Remember the side that connects to the graphics card is STANDARD 6+2 PCIE, but the side that connects to the power supply is NOT STANDARD between manufacturers. If you have a multimeter it would be easy to check which pin leads where, or you can try to find a paper/ask the seller, or you can actually visually confirm by following each wire, since it's a flat cable, didn't think of that.

Thanks, beat me to it. ^^

 

Momkai I would try to find one from the power supply manufacturer. That is your safest bet.

It definitely doesn't look like the same pinout, look at the PSU side of the cable. Please check it over, because on the picture it looks like a different pinout, so please don't blow up your GPU.

The wires are all connected differently.

You can see on the bottom left picture that the wires don't go to the same spot on the PSU side. Don't use this!

I'm ordering a new PSU, thanks all! I don't wanna risk it.

You could just follow each wire from connector to connector and visually compare which wire leads where, start from the ones that look different. Of course if you don't feel comfortable doing that ordering a new PSU is the safest bet.
