Also, we don't know what happens when the minimum load is not met.
In principle, the regulation could be off (so the rails are more
than +/-5% off the normal value). The supply probably doesn't go
crazy. If it was me, I'd search for a supply without a minimum
stated.

Thanks Paul & all. I'm trying to do this on the cheap, using parts I
already have. I can pick up a used SCSI enclosure on eBay for
$20+ shipping, that would include a dedicated PS, but I figger why
spend the money if I can avoid it?

Specs for the Sparkle give a combined wattage rating for both the
5V + 3.3V rails.. Does that mean a load present on one of those
rails will result in a shared load on both? I'm hoping this will satisfy
the 0.2V minimum for 3.3V.

Sorry, that should have been 0.2A, not 0.2V.
