I have an existing PSU plugged into a RadeonHD5970 which I am replacing with a GTX1080.
The Radeon uses a 6pin and an 8pin, and the PSU has two cables that are daisy chained like so:
Currently the radeon is only using one wire as it only needs the 6 and 8:
(PSU)---(6PIN-plugged into Radeon slot 1)---(6+2PIN-Plugged into Radeon slot 2)
However, the GTX1080 uses 2x 8pin, so my question is, is it safe to use both wires coming from the PSU for the 1080, ignoring the first 6pin and using the 6+2pin connectors?
