Cabling System

In Figure 4, you can see the cables that come with the power supply. The cables are UV sensitive, so if you install an UV light inside your case the cables will glow. As you can see, this power supply comes with 10 wire holders, five Velcro holders (which means that they are reusable) and five thin plastic holders. With these holders you can organize the cables inside your PC, improving the airflow.

The motherboard power plug used on this power supply is really interesting: it fits both 20-pin and 24-pin motherboards without using an adapter. Its 24-pin plug can be transformed into a 20-pin plug by detaching the extra wires, which is very easily done, as we show on Figures 5, 6 and 7.

The auxiliary power cable used by PCI Express video cards has an extra filtering feature, as you can see in Figure 8 (we cut the light blue plastic protection to show you the components). Two electrolytic capacitors, two ceramic capacitors and one ferrite tube are used to make this filtering circuit.
