Antec Signature SP Platinum 2200W - PSU, 80 Plus Platinum

The Antec Signature SP Platinum delivers a continuous power output of 2200 watts, engineered for high-demand systems such as professional workstations and multi-GPU configurations. Its 80 PLUS Platinum certification indicates high operational efficiency, resulting in reduced energy consumption and lower heat generation. This unit is compliant with ATX 3.1 standards, ensuring compatibility with current and next-generation high-performance components. The active Power Factor Correction (PFC) further regulates voltage for stable power delivery to sensitive hardware under heavy computational loads.

This power supply features a fully modular cabling system, which permits users to connect only the necessary cables for a cleaner build and improved internal airflow. Thermal management is handled by a single 135 mm fan that operates actively to maintain optimal temperatures, with a documented noise level of 33 dB. The unit also includes a silent mode for quieter operation when the system is under a low power draw. A suite of integrated power protection features, including overcurrent and overvoltage protection, safeguards connected hardware from electrical irregularities.
