Im looking for a good branded power supply that has anything over 45 amps on the +12v rail. I came across the OCZ stealthxtreme 700w PSU which has 4 18A +12v rails. I know that it doesn't really have (18x4) 72 amps, How do I calculate the amps it really has on the +12v rail.

Look into a Corsair, Seasonic, PCP&C or Antec Earthwatts PSU.
They offer the best quality available in the consumer PSU market.

Divide the combine wattage for all +12v rails by 12.
In the case of the OCZ StealthXStream 700W, the 4 +12V rails can deliver a total of 675W combine.
675W/12V = 56.25A available across the +12v rails.
