Use Ohm's law to calculate a suitable output series resistor (R = V / I). Make sure that resistor is rated for the full power of the output.

NOTE: Output voltage regulation will fall by −100% at full load
Authoritarianism is for wimps.

Smart people don't buy "smart" devices without very carefully weighing up the risks and benefits beforehand.

My PC: Core i3 4130 on GA-H87M-D3H with GT640 OC 2GiB and 2 * 8GiB Kingston HyperX 1600MHz, 2 * WD3003FZEX-00Z4SA0, Pioneer BDR-209DBKS, Seasonic G-360, Chenbro PC31031, Windows 7 Pro (though I do want to build a second system with GNU/Linux).
