Manufacturer description

SHARK TECHNOLOGY ATX-400 is a compact 400-Watt power supply with a reduced depth into the PC case to allow for easier installation and free up more room inside the system to facilitate better internal airflow. Strong 80mm turbo fan further ensures hot air inside the system is blown out with or without an extra case fan. Both SATA and Molex 4-pin peripheral power connectors are each laid out on two separate cable lines so drives positioned not adjacent to each other can still be reached.Designed to be an ideal easy-to-install replacement power supply choice for most name brand Intel or AMD…
