Antec CSK1000 PRO ATX 3.1 Bronze SMPS

The Antec CSK1000 PRO is a 1000W semi-modular power supply built to the ATX 12V 3.1 standard, making it a forward-compatible choice for modern high-performance desktop systems. Its inclusion of a PCIe 5.1 12V-2x6 connector (rated at 600W) ensures seamless compatibility with current-generation graphics cards, including the NVIDIA GeForce RTX 40 Series, without the need for adapter cables. Certified 80 Plus Bronze (230V EU), the CSK1000 PRO is designed to operate efficiently under real-world load conditions, helping to reduce heat output and keep system noise levels in check. The 120mm fan is governed by Antec's Thermal Manager system — an advanced low-voltage fan control mechanism that modulates fan speed based on internal temperature, keeping acoustics low during light workloads and ramping up only when needed. The semi-modular cable system strikes a balance between convenience and cable management. Fixed cables handle the essential 24-pin motherboard and CPU connections, while optional modular cables for PCIe, SATA, and Molex peripherals can be attached only as needed, reducing clutter inside the chassis and supporting better airflow. Protection is provided by Antec's CircuitShield suite, which covers eight industrial-grade 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 and Inrush Protection (SIP), and No Load Operation (NLO). These collectively protect both the PSU and connected components under adverse electrical conditions. Antec backs this unit with a 5-year warranty, reflecting confidence in the product's long-term reliability. The compact body measures 140mm (L) × 150mm (W) × 86mm (H), making it compatible with a wider range of ATX cases including some compact mid-towers. Regulatory certifications include TUV, CB, RCM, CE, BIS, UKCA, and KC.
