Hi Power 550W ATX Power Supply
The Hi Power 550W ATX Power Supply is a reliable and versatile unit designed to provide stable, efficient power for a wide range of desktop computer systems. With a 550-watt continuous output, it offers sufficient capacity to support modern mid‑range gaming PCs, office workstations, and home entertainment machines, while leaving room for future hardware upgrades.
Built to comply with the ATX form factor, this power supply fits seamlessly into standard tower cases. Its 12 V rail is carefully engineered to deliver consistent power under load, ensuring your CPU and GPU receive adequate energy even during demanding tasks. The unit includes multiple standard connectors — such as a 24-pin ATX main connector, a 4+4 pin CPU auxiliary connector, and several PCIe, SATA, and peripheral Molex plugs — giving you flexibility to power graphics cards, storage drives, add‑in cards, and legacy components.
Efficiency is a key feature of the 550W Hi Power model. It is optimized for low internal energy loss, reducing heat generation and lowering your electricity bill. A thoughtfully designed cooling system — typically including a ~120 mm fan — provides effective airflow to maintain optimal internal temperatures. The fan operates quietly under moderate load and spins up more actively when the power draw increases, helping to extend component life and reduce noise.
Safety and protection are built in. The power supply incorporates over-voltage, under-voltage, over-current, short‑circuit, and over‑temperature protections. These ensure that any unexpected electrical event is safely handled without damaging your sensitive hardware. The housing is constructed from flame-retardant materials, and the internal components are selected for durability and reliability.
Cable management is another area where the Hi Power 550W excels. The cables are long enough to reach all areas of standard PC cases, and their sleeving or plastic sheathing helps prevent tangling, improves airflow routing, and promotes a tidy internal layout.
Overall, the Hi Power 550W ATX Power Supply provides a dependable balance of power output, efficiency, safety features, and expandability. It is an excellent foundation for users who are building a dependable, mid-tier PC that demands reliability without premium pricing.
