Botton to top: cablemod, EVGA stock, offical EVGA custom sleeved
 
Cablemod pinout is all out of wack. They keep insisting to everyone that it is based on the official EVGA sleeved cables, including to me. I didn't accept that as true because i own the official cables as seen above, i showed pictures of stock, official sleeved and their cables . They have the 17th and 3rd pin on the 18 pin PSU plug running to the 20th pin on the 24 pin plug which is the 2 x 3.3v running to the defunct -5v pin.
 
Apparently this is quite common with their cables, either by design or poor quality control. I've done some research reading about PSUs/hawardware dying with these cables, and after showing them enough pictures they said they would look into it.
 
I'm waiting for a response and will update accordingly. For now unless you want to repin some cables, i wouldn't buy cablemod.
