Review DELL Genuine Sff 220w Atx Power Supply Psu Screws

The Dell MC638 SFF 220W ATX Power Supply (HP-Q2228F3P) is a high-performance, compact power supply unit designed for Small Form Factor (SFF) systems. This power supply delivers a maximum output power of 220 watts, making it suitable for most entry-level to mid-range desktop computers.

This power supply unit comes with a standard ATX form factor and is mounted using screws. The screws for mounting the power supply to the case are not included in the package, so you will need to have them on hand if you plan to install this power supply in a system. The screws required are not specified by Dell, so it's essential to check the documentation of your specific system to determine the correct screw size and type.

The HP-Q2228F3P power supply features active PFC (Power Factor Correction) technology, which ensures optimal power delivery and reduces power loss. This technology also helps the power supply comply with energy efficiency regulations such as ErP Lot 6. The power supply also includes over-voltage, under-voltage, over-current, and short-circuit protection to safeguard your system components.

The power supply has a 120mm fan for cooling, which operates silently and efficiently. The fan speed is regulated by the power supply's temperature sensor to ensure optimal cooling performance while minimizing noise. The power supply also has a modular design, allowing you to use only the cables that you need, reducing clutter and improving airflow within the case.

The Dell MC638 SFF 220W ATX Power Supply (HP-Q2228F3P) is a reliable and efficient power supply that provides ample power for most SFF systems. Its small form factor, active PFC technology, and modular design make it an excellent choice for system builders looking for a high-performance, compact power supply. However, be sure to have the correct screws on hand before installing the power supply in your system.
