Plus Bronze at that price is nuts.

+12V Rails   2

Output   +3.3V@24A, +5V@24A, +12V1@20A, +12V2@20A, -12V@ 0.5A, [email protected]

 

Not terrible, but not great either.  I would trust it with 6 drives, or maybe up to 10 green drives.

To be honest, I really have no clue as to what these numbers mean but would like to know.

 

Care to give a "tutorial"?

 

What uses the various Volts?

 

I assume for the HDD you would look at the +12V for number of Amps?  And I guess it is 2A per Green Drive?  How many for a 7200RPM Drive?
