GTX 1080 FTW2 dual 8 pin.. can one 6 work?

[Copyright]

My last card had an 8 pin and 6 pin connection which I had custom cables made to match up. My new GTX 1080 FTW2 has dual 8 pin. is it safe to use one 8 and one 6 on this card? I thought the 1080 worked on a single 8 pin normally.

Sure you can, with an adapter.

No, you cannot just plug a 6-pin male into an 8-pin female and expect it to work. Those two extra pins are there for a reason.

It is fucking funny that you can literally splice a two pinned plug on from the existing wires but not just run a 6 pin.

yup but those two extra pins are there for a reason...

The extra pins are mostly to guarantee that there's sufficient wattage.
If there is, it'll work without issue. If not, it could put undue strain on the PSU and possibly not even work and/or crash.
