The ASUS Atlas A-45GA 450 W is 5 ½” (140 mm) deep, using a 120 mm fan on its bottom. The fan used is a Yate Loon D12SH-12(F).

This unit features a PFC circuit.

No modular cabling system is provided and only the main motherboard cable has a nylon protection that comes from inside the power supply housing. All cables use 18 AWG wires, which is the correct gauge to be used, except the +3.3 V (orange) wires of the main motherboard cable, which are thicker (16 AWG). The cables included are:

  • Main motherboard cable with a 20/24-pin connector, 17” (43 cm) long
  • One cable with one ATX12V connector, 17” (43 cm) long
  • One cable with one six-pin connector for video cards, 17 3/8” (44 cm) long
  • Two cables with two SATA power connectors each, 17 3/8” (44 cm) to the first connector, 5 7/8” (15 cm) between connectors
  • One cable with three standard peripheral power connectors, 17 3/8” (44 cm) to the first connector, 5 ½” (140 mm) between connectors
  • Two cables with two standard peripheral power connectors and one floppy disk drive power connector each, 17 3/8” (44 cm) to the first connector, 5 ½” (140 mm) between connectors
  • One cable with a three-pin fan power connector for you to monitor the speed of the power supply fan through monitoring software, if this connector is installed on the motherboard

This configuration is adequate for a low-end PC.
