Bitmain is being conservative, and it's good that they are - consider the difference between an S3 (350W, 4 jacks) and a KNC Neptune (400W, 1 jack). Which has a better track record for not bursting into flames?
400W can be run off two cables if you have good cables. I wouldn't trust 18AWG for more than about 150W where I'd trust 16AWG for 250 without batting an eye. My opinion, it's safe with two cables if you have good cables. If it makes you feel any better, I ran about 30 AM Tubes (200W per module) off a single 16AWG cable per module for six months without a single issue.

Hehe Im quite confused. When you speak of good cables do you mean the quality of my PSU PCI cables? Or are you referring to the internal wiring of my house?
