Enermax Tomahawk 500 W is a short power supply, being only 5 ½” (14 cm) deep, using a 120-mm fan on its bottom and active PFC circuit, of course.
Being an entry-level product, it doesn’t have a modular cabling system. Only the main motherboard cable and the ATX12V cable have a nylon protection. All cables use 18 AWG wires, which is the minimum recommended.
