No such thing as a stupid question. Stupid is not asking.
Yes, that power supply will easily handle even a 4 lane 1/32nd track. It looks like its adjustable up to 30 amps, and you'll never need that much. I have a very similar, older version, and it will max out at 50 volts, 30 amps. It has never been set above 13 volts, 10 amps, and does fine.
