This is a smart car DC ATX power supply with ITPS function, capable of controlling motherboard power on/off based on the car's ignition status, delivering a maximum output of 180W. When the car is turned off, the X5-ATX sends a shutdown signal to the motherboard to power down the computer. It then waits for 90 or 600 seconds (selectable via jumper cap) before cutting off the +5VSB standby voltage, protecting your car battery from draining by a traditional ATX power supply during prolonged periods of inactivity. The X5-ATX continuously monitors the car battery voltage during operation. If the battery voltage drops below 11V for more than 60 seconds, the X5-ATX will shut off all voltage outputs and will not resume until the car battery voltage exceeds 11V. Features engine cold start, overvoltage, undervoltage, and overcurrent protection. The X5-ATX operates with an input voltage range of 6-25V, ensuring normal function even when the battery voltage drops to 6V during engine cold start. Additionally, the input end of the X5-ATX is equipped with a surge protection tube and a 15A/40V fuse for overcurrent protection, making it suitable for building safe 12V battery-powered computer systems. Note: Due to variations in production batches, the components on the power board may differ from the images, but the functionality remains the same and does not affect usage. Features a fanless design for absolute silence, supports battery input, and is ideal for car PCs, home entertainment computers (HTPCs), mini PCs, and industrial control hosts.
