Adding power moles to your extenders! Easy.....

Hey,

 Had a good question so thought id share it. Save yourself loads by adding a power molex to your extenders as to not blow your motherboards with more than 4 cards in it...

Basically its 5 wires that go to YOUR YELLOW cable on the molex. 3 from 1 side (including the red one) and 2 from the other(leaving the red one connected. Pic shows it better. Each PCI-E sucks 75W so after 4, drawing over 300W from a mainboard (unless a high quality mobo) isnt a wise idea. I blew a crappy gigabyte (which i say avoid the new ones, ive had 3 failures of AMD gigabyte boards).

By doing this you draw it from your PSU instead and skip the motherboard

It would be nice to get a more detail on how to do it.

Im not the best at explaining things, never have been. Out of the 6 wires where the 2 RED/PINK wires are on your extenders at one side (X1 side obviously), you cut 5 of them, Leaving one red/pink connected to the motherboard.

Side with 3 cables cut (1-3, 1 been red/pink)

Side with 2 cables cut (2-3) LEAVING RED/PINK CONNECTED

Thanks for posting!

For further reference if it wasn't clear enough for you
Side B pins 1,2,3
Side A pins 2,3

As pin 3 on side B is 'reserved' does it have to be connected? is this the power up lane?

Thanks for clearing that up, I just copied cablesauraus technique after ordering (a rather expensive) one off him. Cost me £20 compared to £3.60 to do myself
