Can I follow up on this. The unit arrived today and has only 2 x SATA 
power outputs. The two cables have 4 x SATA sockets on each, ironic as 
that is what I had so much trouble finding for the Seasonic.

The relevant spec is:

DC Output Rail Ratings
+5V: 20A (Max 110W)
+3.3V: 20A (Max 110W)
+12V: 70.8A (Max 850W)
+5Vsb: 3A (Max 15W)

Can you calculate from that if I can safely run all 4 3.5" Iron Wolf 
(5,400 RPM) from one cable and should I run two from each?
