EVGA - What would you pay for PCIE cables?

Now I recall it was where you connected the cables from the SPU to the other extension that had only a 6-pin connector, I think. Is that right?

Shown is a black NZXT 6-Pin to 6+2Pin VGA Extension Cable connected to typical power supply cable (red). So....

The red side connected to the (modular) power supply will have a 6+2 pin at other end (yellow & black circle).

The black side is a 6+2 pin and is connected to either a 6 or 8-pin GPU. If connected to a 6-pin GPU, the 2 pin connector would just be dangling like that shown in the yellow circle.



The extra 2 pins are simply extra ground cables; Thus the reason most extension cables for the GPU just utilize 6-pins on one end with the 2 extra ground pins on the other end sharing a common ground at the 6-pin side as shown in the example above with the black NXZT extension cable.

Some power supplies utilize a true 8 pin power configuration for those GPU's requiring 8 pins, especially as GPU's become more and more powerful. You have to figure there's a reason a GPU was designed with 8 pins in mind instead of 6.

Anyway there was a discussion here - Pci-e cables 'actual limits vs artificial limits' - jonnyGURU Forums


How this clarifies

Britton30 said:

I just look you GPU up, two 8-pin connectors.

Yep, it takes two 8-pin connectors. And, as I said before, if Sapphire wanted 6 pin connections, they would have made it 6-pin. Am I being overly "cautious", perhaps.

You wanted to fix the "dangler" you had in the yellow circle.

Not necessarily dangling, but un-used pins coming from the PS to the GPU

That image is of my old extension cable with only had 6-pins on one side, which is why I wanted a "true" 8-pin cable. See this post for the 8-pin cable image - EVGA - What would you pay for PCIE cables?

Then read from here - EVGA - What would you pay for PCIE cables?

Bottom line, no pins or connections are dangling...

Single 8 pin pci-express cable with 8 pin and 6 pin piggyback. Is this safe to use on a card with an 8 pin and a 6 pin input connector ?
EVGA is telling me it is

Yes. For cards requiring only six pins, the other two (split) are just left dangling since they're not used. For cards requiring 8-pin connections, those two extra pins would be used.

Since my card requires 8-pin connections, and I didn't want red cables, I went with a true 8-pin extension so no pins would be dangling at either end

BTW those are the same cables that came with my PS as well. I got six of those red cables in all. Two like the ones you show, and four like the ones shown here.

Nice pics and cabling job Drew. I like the green SATA cables going with the green board highlights.

Thanks. Yeah I thought that was a nice touch. BTW those particular green cables are just going to my hot swap bays. Wanted something to distinguish them from the others :)
