I have EVGA’s Z77 FTW motherboard as described here: http://www.evga.com/support/manuals/files/visual/151-IB-E699_Visual_Guide.pdf
There are two inputs for 6-pins ATX power for PCI slots 2, 3, 4, and 5. One connector is just above slot 1 towards the left end and the other connector is at the lower left corner of the motherboard (90-degrees bent connector).
My PSU is Corsair AX850. http://www.overclockers.com/forums/showthread.php?t=697193
One 8-pins connector (EPS) is available in the green boxed rectangle in the above illustration.
My question is “Can I use an 8-pins cable with a Y-splitter and detach 2 pins from the motherboard end and then plug in the 6 pins into the PCI ATX power connectors?”
Suggestions for alternate approaches are also welcome.
