I have a Corsair AX1200 Gold PSU.

It will power 3 GTX 670s, the mobo, a 3930K oc'd to 4.5ghz, 6 SSDs, and:

24 3-8TB green drives.

1. I know it can power all this because it has but...
2. How many drives can it power off of one 3 SATA prong cable? I'd like to reduce the cable clutter in the case by daisy chaining multiple 1 to 4 SATA connectors.

Okay, so each SATA connector has 3 pins for 3.3V, 5V and 12V. Each of these pins can carry up to 1.5A. So one SATA connector should be capable of powering drives using up to 4.5A with each of those voltages. What specific drives do you have?

Alright, well those use up to 1.73A each (source), all of that's using 12V. So you'd be able to power at least two drives per SATA connector, three at a push.
So if you connect each connector to two drives you'll need to use four of the cables, if you go for three per connector you'll need three of the cables.
