4pin square pinout and capacity?

I recently bought a 430W PSU for my bp6 machine. It has an unused 4pin sqaure connector(for fans on newer mobos if I remember correctly).
I was wondering if there would be any benefit to switching some of my case fans to this connector, and if so what is the pinout for it and how many case fans could it handle? I poked around and could not find much info for this particular connector.

This connector is part of Intel's new spec for ATX psu's. It's meant to bring 12 volt current directly to where it's needed on server style ATX motherboards.

Since it's a 12 volt, and uses the same color coding as the molex connectors, I'd expect them to come from the same circuit internally. This being the case, if your fans are plugged into molex connector's right now, there's little reason to switch them to the smaller plug, but you can if you want to. If your using the fan headers on the mobo, then go ahead and switch to the other connector.

Just use the same codes as for a molex (drive connector) ...yellow =(+) 12 volts, black = ground (-)
The capacity (amps) would depend entirely on your power supply, as there doesn't seem to be a spec set for this.

Have fun!

Doh! Since it is probably coming from the same circuit there doesn't seem to be much use in switching them. No use in fixing what ain't broke.

Thanks for the info Diggrr.
