Despite its compact SFX design, the SF850 delivers a robust 850W output, making it ideal for power-dense gaming systems and professional workstations. Officially certified for ATX 3.1 compliance, this power supply meets the latest reliability and efficiency standards while offering native support for PCIe 5.1 hardware. An included 12V-2×6 PCIe 5.1 GPU cable ensures seamless compatibility with next-generation graphics cards, including NVIDIA GeForce RTX 40 Series GPUs. With 80 PLUS Platinum certification, the SF850 achieves exceptional power efficiency, reducing heat generation and energy waste while improving long-term component reliability. Built using 100% industrial-grade 105°C-rated Japanese electrolytic capacitors, it guarantees stable power delivery even under continuous high-load operation at temperatures up to 50°C. Cooling is handled by a quiet 92mm PWM fan with Zero RPM mode, allowing completely silent operation at low to medium loads while ramping up only when necessary.
