Gotcha. I actually haven't tried powering up a SATA drive without a data connection... what happens if you do? Does it spin up? If so, then does the hard drive detect that a cable is present through some sort of always-open circuit between the sata cable and the motherboard?

I updated my post for the interrupt signal as well.

A SATA drive will power up normally without a data plug.
Once again...

Ok, thanks.

Here's an example: http://www.jonnyguru.com/modules/NDR...W/DSC01271.JPG

And another:

http://www.jonnyguru.com/modules/NDR...K/IMG_0802.jpg

Note the two separate maximum combined ratings for +12V? These PSU's truly have two independent +12V outputs. These outputs are then split up again and capped off with OCP's.

In the middle of it, it lists two +12v rails with a max draw of 12A and 14A each, but below that, the maximum wattage is only 180w. If the power supply could truely handle 12A and 14A on both rails at the same time, it would be outputting (12+14)*12 = 312w. Thus, this PSU must be a single-rail split into two.

So really, you're saying that the true capabilities of a PSU should be measured by the wattage listed below the 12v rails, not the maximum amperage available on each 12v line?
Like I said in one of the first posts in this thread: The amperage rating underneath the voltage (+12V1, +12V2, etc) is not a measure of capability, but a designation of a limit to how much power can be delivered on a particular rail. The only measure of capability is the wattage number underneath this.

Jeeze, this thread really took off eh?
Good work to all those posting info, I'm learning a fair bit here.

1000W is extremely unnecessary... ATM 750 is good for almost any high-end system.
