With respect, taking other components off the PSU isn't necessarily going to get it working. The 12V load is the important aspect of the system and removing all hdd's isn't going to affect this.
The Q6600 and Aquagate isn't helping with this as well I'm afraid.
The SXS isn't a particularly great PSU as it's based on a line of PSU's going back through the GXS 700W and FSP 700W models that were notoriously bad at regulating the 12V rail under high load. This leads to voltage ripple, and ripple is what kills components.
Basically, it might work. That means you might press the button and it powers up fine and initally works fine. You might run into problems when you enable SLI and you start getting dodgy scores or you system start crashing. Even if all that doesn't happen and it runs fine, you're stressing an average PSU and that's never good with pricey components.
If you're going to SLI, then get a new, quality, 700W+ PSU (Corsair, Seasonic, Silverstone, Enermax etc).
