so regarding balancing, how do i do that? how do i know on what rail what cable is? this psu (akasa venom power) has native cables (2 6+2, motherboard cable, cpu cable) plus 4 6+2 modular cables (picture at bottom)

1. i assume each pciex 2*6+2 cable belongs to a separate 12v rail so i have to connect each card with one 6+2 connector from one cable and other 6+2 connector from other cable? then the card is balanced?
2. now how do i proceed with 12v for motherboard and cpu cables? how do i know whether they are not at their own 12v rail?
3. evga titan has 42A so if i put it on single rail psu might restart the pc?

PS: my pc has only single ssd and dvd drive so i wont be actually running any heavy equipment beside 1-2, possibly very unlikely 3 gpus

thank you

they write its dynamic single rail, but in rewiew of 850w it was revealed that its just advertised as single rail but actually has 4 12v rails

One thing I couldn't understand though is Akasa's decision to advertise it as a single rail unit, while, in fact, it has four +12V rails with a high OCP trigger point (40 A). I am aware that most users think that single rail PSUs allow higher overclocks, but that is just a myth. If the OCP triggering point is at the right level, a multi-rail PSU is actually safer than a single rail one.
