ANTEC CSK1000 Pro 1000W 80+ Bronze Semi Modular ATX 3.1 Power Supply

The Antec CSK1000 Pro is a 1000W semi-modular power supply built to the ATX 12V 3.1 specification, making it a solid foundation for modern high-performance desktop builds. Rated 80 PLUS Bronze certified (230V EU), it delivers continuous 1000W output across an operating temperature range of 0°C to 40°C, helping keep your system stable under sustained workloads. Cooling is handled by a 120mm silent fan managed by Antec's Thermal Manager, a low-voltage fan control system that adjusts fan speed in response to internal heat levels, balancing acoustic performance with thermal headroom. The result is quieter operation during light loads without sacrificing airflow when power demands increase. Safety is covered by Antec's CircuitShield protection suite, which incorporates eight independent safeguards: Over Current Protection (OCP), Over Voltage Protection (OVP), Under Voltage Protection (UVP), Short Circuit Protection (SCP), Over Power Protection (OPP), Over Temperature Protection (OTP), Surge & Inrush Protection (SIP), and No Load Operation (NLO). Active PFC ensures stable power factor correction across the supported input voltage range of 200V–240V at 50Hz. The included PCIe 5.1 12V-2x6 connector (600W rated) provides native compatibility with current-generation discrete graphics cards such as the NVIDIA GeForce RTX 40 Series, eliminating adapter requirements. The semi-modular design keeps essential cables — the 24-pin ATX motherboard connector and CPU connectors — permanently attached, while peripheral cables are detachable to reduce clutter and improve case airflow. Antec backs the CSK1000 Pro with a 5-year warranty and the unit carries multiple regulatory certifications including TUV, CB, RCM, CE, BIS, UKCA, and KC.
