SOEYI Power Supply Series

SOEYI Power Supply Series – Product Lineup & Competitive Edge

Version 1: Half-Bridge

·        Power Range: 200–300W

·        Voltage Support: 180–264V

·        Efficiency: ~65%

·        vs. Competitors: SOEYI retains a complete EMI filter circuit for better stability. Most competitors omit EMI filtering entirely in low-wattage models.

Version 2: Double Forward (Standard)

·        Power Range: 350–750W

·        Voltage Support: 170–264V

·        Efficiency: 75–78%

·        vs. Competitors: Uses FR-4 fiberglass PCB – heat & moisture resistant. Competitors often use cheap paper-based PCBs, which are prone to short circuits and poor heat tolerance.

Version 3: Double Forward + DC-DC

·        Power Range: 350–850W

·        Voltage Support: 170–264V

·        Efficiency: ~82%

·        vs. Competitors: Equipped with 105°C high-temp capacitors and thickened heatsinks. Competitors in the 500W class often use 85°C capacitors with undersized heatsinks, significantly shortening lifespan under full load.

Version 4: Active PFC + DC-DC

·        Power Range: 450–1000W

·        Voltage Support: 90–264V (true wide-range)

·        Efficiency: 86–88% (Bronze-grade ~85%)

·        vs. Competitors: SOEYI delivers genuine wide-voltage input – ideal for unstable grids. Many competitors claim "wide range" but are actually fixed 220V designs, leading to high failure rates.

Version 5: LLC Resonant + DC-DC (Flagship)

·        Power Range: 550–1600W (market mainstream: 850–1200W)

·        Voltage Support: 90–264V (global wide-range)

·        Efficiency: 96%+ (80 PLUS Gold–level)

·        vs. Competitors: Fully modular cabling with ultra-low output ripple – safe for high-end GPUs. Competitors in this class often suffer from power rating inflation, uneven load distribution, or poor dynamic response.

Core Differentiation – Side-by-Side Comparison

Key Takeaway

From entry-level to high-end, SOEYI maintains safety essentials (EMI, PCB quality) while leveraging technological advantages (wide-range voltage, high-efficiency architectures) to outperform competitors at every price point.

Competitive Highlights – At a Glance

·        PCB Quality: Black FR-4 board – heat & moisture resistant vs. cheap paper-based alternatives.

·        Voltage Flexibility: True 90–264V wide-range support vs. narrow 200–240V – better adaptability to unstable power grids.

·        Transparent Build: Our tear-down videos clearly show full EMI filters, adequate capacitor ratings, and thicker heatsinks – no shortcuts.
