2. Interface type, Efficiency rating, Brand

3. Color, Size, Weight

4. Warranty period, Manufacturer, Price

The correct answer is: Form factor, Output wattage, Type of connectors

When replacing a power supply, it is essential to consider the form factor, output wattage, and type of connectors. The form factor is important because it determines the physical size and shape of the power supply, ensuring that it fits properly within the case of the computer. Power supplies come in different sizes, such as ATX, SFX, and more, and selecting the correct form factor is crucial for compatibility. Output wattage refers to the total amount of power the power supply can deliver to the components of the system. It is vital to choose a power supply with a sufficient wattage rating to support all installed components, including the motherboard, CPU, graphics card, storage drives, and peripherals. Underpowering the system can lead to instability, crashes, and potential hardware damage. The type of connectors is also critical because different hardware components require specific types of power connectors. For instance, modern graphics cards and motherboards often require particular connectors such as 6-pin or 8-pin PCIe connectors, as well as the main ATX power connector. Ensuring that the power supply has the necessary connectors is essential for successful installation and operation. Considering these specifications helps ensure that the new power supply will be compatible, adequately supported, and able to
