• Mining-Exclusive Design:

• Multi-Channel Independent Power Supply: 8 +12V outputs with independent voltage division prevent current crosstalk during multi-GPU parallel operation, enhancing system stability.

• High Conversion Efficiency: Although not 80+ certified, typical load efficiency reaches 85%+, combined with dual-fan strong cooling for 24/7 mining scenarios.

• Industrial-Grade Durability: SECC 0.6mm high-strength casing with overcurrent/overvoltage protection reduces hardware risks during long-term operation.

III. Core Technical Advantages of 1200W+ Power Supplies

1. 80+ Certification and Energy Efficiency Revolution:

• Platinum/Gold certification ensures high conversion efficiency at 20%/50%/100% loads. Take RGB PRO 1300P as an example, it saves about 300 kWh annually compared to Bronze PSUs, while reducing heat generation.

2. Technological Foresight of ATX3.1 and PCIe5.1:

• Native support for 12V-2x6 interfaces meets the 300W+ transient power demand of PCIe5.1 GPUs (e.g., RTX 4090’s 12VHPWR interface), avoiding safety hazards from adapters.

3. Topology and Component Quality:

• LLC resonance + DC-DC synchronous rectification topology reduces ripple noise. Japanese Nichicon/Rubycon capacitors (life ≥100,000 hours) and alloy inductors enhance stability, suitable for server-grade 7x24 operation.

IV. Buying Guide for High-Power Power Supplies

1. Power Redundancy and Scenario Matching:

• Gaming rigs: (CPU + GPU TDP) × 1.5 (e.g., i9-13900K + RTX 4090 requires 1300W+).

• Workstations/mining: Reserve ≥20% power for multi-hardware parallel operation (e.g., 6x RTX 3080 suggests 1650W+; refer to GM-1650 BK).

2. Certification and Efficiency Priority:

• High-end users prefer Platinum/Gold certified models (e.g., RGB PRO 1300P) for energy saving and low heat; budget-conscious users can consider Bronze-certified high-power models (e.g., GP series).

3. Modularity and Compatibility Details:

• Fully modular design suits cases with high cabling requirements; ATX3.1/PCIe5.1 interfaces reserve space for 3-5 years of hardware upgrades.

V. Conclusion: High-Power PSUs as "Guardians" of Hardware Performance
