• Recommendations: To unlock the system's potential, particularly for the integrated GPU, it is recommended to use two memory modules (for example, 2x8 GB or 2x16 GB) with a frequency of at least 3200 MHz and low timings (CL16 or lower). The video memory for the iGPU will be dynamically allocated from the system RAM.

4. Power Supply Requirements

With a nominal TDP of 35W, the processor imposes minimal demands on the power system.

• Power Calculation: The primary consumers in a system based on this APU will be the motherboard, storage drives, and case fans.
• Recommended Power Supply:
  • For a system without a discrete graphics card, a quality power supply rated at 300-400W is sufficient.
  • When installing a discrete entry-level or mid-range graphics card, it is advisable to use a power supply rated at 450-550W from a reputable brand (with 80 Plus Bronze certification or higher).
• Key Criteria: For a 24/7 operating system, the stability of voltages, quiet operation, and high efficiency of the power supply are important.
