## Long description

The Akyga AK-U4-350 350W 20+4 pin ATX Black is a 350 W ATX power supply unit designed for desktop PCs. It supports ATX 2.31 compatibility and delivers continuous power for typical home and office systems as well as modest gaming or multimedia builds. The unit uses a 20+4 pin motherboard connector and includes a range of fixed cables: 4x SATA, 2x Molex, PCI‑E 6+2 pin, mini‑Molex, and EPS12V 4+4 pin. A 12 cm fan with automatic speed control and a chromed grill provides active cooling, while a manual on/off switch and a supplied 1.5 m power cord simplify installation and operation. The power supply meets safety and environmental standards (CE, RoHS, REACH) and carries an 80 PLUS Bronze efficiency rating.
Advantages
The unit offers stable continuous output of up to 350 W with 80 PLUS Bronze efficiency to reduce energy loss and heat. Active PFC improves power factor and voltage stability, and built‑in protection mechanisms (OVP, OCP, OPP, OTP, SCP, UVP) protect connected components against overvoltage, overcurrent, overpower, overtemperature and short circuit conditions. Non‑modular cabling ensures simple, reliable connectivity and the range of connectors supports common drives, add‑in cards and CPU power requirements. The 12 cm fan operates with automatic speed control to balance cooling and acoustic performance.

How to use
Turn off and unplug the computer before installing the power supply. Mount the unit in the case according to the chassis instructions and secure it with screws. Connect the 20+4 pin ATX cable to the motherboard and attach the EPS12V 4+4 pin cable to the CPU power header. Plug the PCI‑E 6+2 pin connector to the graphics card if required, and attach SATA or Molex connectors to storage drives and peripherals. Connect the supplied power cord to the unit and the mains, then switch on the manual on/off switch and power up the PC. Verify stable boot and monitor voltages and fan operation during initial startup.
Usage recommendations
Use this power supply in systems with total power consumption within the 350 W rating and allow for adequate airflow inside the case. Avoid overloading the unit with multiple high‑power components; for multi‑GPU or high‑end CPU systems choose a higher‑wattage supply. Periodically check cable connections and keep the fan and ventilation areas free of dust to maintain cooling efficiency and prolong service life.
