Will this power the flux capacitor?

Unfortunately, not nearly enough power. At 300W, we would need 4 million SPD3303X-Es to reach the 1.2 GW needed to power the original flux capacitor as well as 4 million power cords, 4 million outlets, etc.. it would be a bit of a challenge :) - Jason, SIGLENT NA

does it have a current limiting feature?

Yes, the two main outputs each have a programmable current limit with the same fine granularity as voltage setting. The third 3.3/5V output I think is a fixed limit.

How does it behave when powered up from the ac input? does it begin working with last settings, or must the soft power button be pressed to start?

This has a hard power switch, you can tell by looking at the power button the line in the middle does not touch the circle. when you power it up, your last settings used will still be there but it will not be enabled. Hope this helps.

Can you adjust the tree outputs?

I assume you meant three instead of tree. However, channel 1 & 2 (0-32 volts)are adjustable. The three outputs of 2.5, 3.3, and 5 volts @ 3.2 amps are fixed and selectable by a slide switch. A comprehensive user manual is available for this power supply that details all the features. Very happy with mine!
