+======= ATX ======
+A 4.7Ω power resistor is used to draw power on the 5 V rail.
+This improves the 12 V rail.
+The ATX [[http://www.formfactors.org/developer%5Cspecs%5CPower_Supply_Design_Guide_Desktop_Platform_Rev_1_2.pdf|Power Supply Design Guide for Desktop Platform Form Factors]] ({{led_light_controller:atx_psdg_v1.2.pdf|archive}}) shows the relation between the load of these two rails.
