StealthXStream 400 W is 6 19/64” (160 mm) deep, has a 140 mm fan on its bottom, featuring active PFC, of course.

All cables use nylon sleevings, but they don’t come from inside the power supply, as you can see in Figure 2. The included cables are:

  • Main motherboard cable with a 20/24-pin connector.
  • One ATX12V cable.
  • One cable with one six/eight-pin auxiliary power connector for video cards.
  • One SATA power cable with four SATA power connectors.
  • Two peripheral power cables with three standard peripheral power plugs and one floppy disk drive power connector.

The number of cables is perfect for an entry-level or mainstream PC. All cables have 20 7/8” (53 cm) between the power supply housing and the first connector on the cable. On the peripheral power cables there is 5 7/8” (15 cm) between connectors. All wires are 18 AWG, which is the correct gauge to be used.
