One of the unique features from this case is the presence of a laptop-style 65 W external power adapter (19 V, manufactured by Delta Electronics), as shown in Figure 10. Inside the case there is a DC-DC converter to transform the 19 V DC provided by the power adapter into +12 V, +5 V, +3.3 V, +5VSB and -12 V. Since we have the necessary equipment, we decided to test this power supply to see if it can really deliver 65 W and what is the quality of the outputs (i.e., noise and ripple).

The cables provided by the DC-DC converter are:

• Main motherboard cable with a 20/24-pin connector, using 20 AWG wires.
• ATX12V cable, using 22 AWG wires on the yellow wires and 20 AWG wires on the black wires.
• SATA power cable, with two SATA connectors, using 20 AWG wires.
• Peripheral power cable, with two standard peripheral power plugs, using 20 AWG wires.

All cables are very short, having only 9 1/16” (23 cm) between the converter and the first connector on the cable and 4” (10 cm) between connectors, as we would expect on such a small case. The wires are thinner than normal, but at only 65 W maximum power they seem to be using the correct gauge.
