4 18amp 12v rails

post #1 of 5
Thread Starter 
Ive just bought a new psu. ocz 700 watt stealth stream 2 and i noticed it has got 4 12v rails all at 18amp.


will this be sufficient for todays top end graphics cards? only a single one, not sli or crossfire or should i have gone for a psu with 1 massive 12v rail?

What difference does it make having the 12v split into 4 instead of 1 or 2 big ones?

Basically it doesn't matter.

Sometimes not all the amps from every rail can be utilized. Generally 2 is the best option.

Actually the more OCP rails the better. It reduces the load on any given circuit and makes it less likely that the OCP will be tripped. In a perfect world each individual wire would have its own OCP circuit--but that would double the cost of a given power supply.
