I'm looking to build a new triple 6990 rig and I'm wondering if anyone can help me with a choice of power supplies.

I know that a lot of you in the community use the AX1200 which here in Australia is more expensive then the Strider 1500W.

So I'm not sure which one to choose; the AX has a single +12v rail where as the Strider has 8 +12V rails but has a higher wattage.
