I would like to use this case http://www.silverstonetek.com/product.php?pid=452 for my NAS build. It requires an SFX ("micro ATX") form factor PSU. The problem is.. I can't even find such a PSU with enough SATA power connectors. Not even 4 SATA and 4 Molex (with adapters).

Silverstone's own SFX PSUs are only 3xSata and 2xMolex. I saw some Molex to 2 SATA adapters on amazon but even that would not be enough (plus, I am not sure if that's even an OK thing to do).

What am I missing?

A single SATA or Molex cable is electrically far more than capable of powering two hard drives. Nothing to worry about unless you intend to daisy chain all eight drives into the same molex header, though even that might work, I just don't know if anyone's tried :D.

A modern hard disk consumes about 5-10 watts at full load. For eight drives, that's 40-80 watts, technically a single molex connector can provide enough juice for a graphics card that consumes more power than that.
