2. M2x, M3x, M5x series fans operate at full speed: 7000~7500RPM, Max power consumption of one fan: 108w, Maximum air volume of server fans: 350CFM;
3. Power cord specifications: 3*1.5mm², 3*2mm², 16A;
4. Required ambient temperature:-5℃~35℃ (When the altitude is ≥2000m, the maximum operating temperature decreases by 1℃ for every 300m higher than the altitude);
5. Recommended AC voltage: 220V~240V (Note: too low or too high AC voltage will damage the PSU);
6. Recommended ambient humidity: 20%~80%;
