A technician is replacing a power supply. Which two factors should the technician consider when obtaining the replacement part? (Choose two.) type of case wattage $$ \square $$ number of internal fans input voltage level of 12 or 5 VDC $$ \square $$ output voltage

Question

UpStudy AI · Accepted Answer

When replacing a power supply, **wattage** and **output voltage** are the two most critical factors to consider:

1. **Wattage**:
   - **Importance**: Ensures that the power supply can handle the total power requirements of all components in the system.
   - **Consideration**: Calculate the total wattage needed based on the components (CPU, GPU, drives, etc.) to prevent system instability or hardware damage.

2. **Output Voltage**:
   - **Importance**: Guarantees compatibility with the motherboard and other components by providing the correct voltages (typically +12V, +5V, and +3.3V).
   - **Consideration**: Verify that the output voltages match the specifications required by your system to ensure proper functionality and prevent electrical issues.

**Other Factors (Less Critical but Useful to Consider):**

- **Type of Case**:
  - Ensures the physical size and mounting points of the new power supply fit your computer case (e.g., ATX, Micro-ATX).
  
- **Number of Internal Fans**:
  - While not as critical as wattage and voltage, having an adequate number of fans can aid in proper cooling.

- **Input Voltage Level**:
  - Generally standardized (e.g., 100-240V AC) and less of a concern unless you're operating in a region with a unique power requirement.

**Summary**: Focus primarily on selecting a power supply with the appropriate **wattage** and **output voltage** to ensure compatibility and reliable performance of your computer system.

**Correct Factors to Consider**:
- **Wattage**
- **Output Voltage**
When replacing a power supply, the technician should consider **wattage** and **output voltage**.
