ANTEC CSK1000 PRO ATX3.1 SEMI-MODULAR 1000W POWER SUPPLY (80 PLUS BRONZE, PCIE 5.1, ATX 3.1 CERTIFIED) | CSK1000 PRO

The Antec CSK1000 PRO ATX3.1 is more than a power supply. It’s the electrical backbone of your high-performance PC, engineered with precision to support next-generation systems with unwavering reliability and operational efficiency. Drawing from Antec’s legacy of innovation, trusted by builders and gamers alike, the Antec CSK1000 PRO is designed to handle the demands of modern computing environments with intelligence, versatility, and confidence.At its core lies a 1000W continuous power output, certified under 80 PLUS® Bronze standards to deliver up to 90% efficiency under typical loads. This translates into reduced energy consumption, lower thermal output, and ultimately, a more stable platform for your most intensive tasks—whether you’re rendering large-scale assets, deep into a gaming session, or running demanding productivity suites.The CSK1000 PRO is fully ATX 3.1 certified, meeting the latest Intel power delivery specifications. It also introduces support for PCIe 5.1, with a dedicated 12V-2×6 connector (capable of delivering up to 600W) designed to power the newest generation of graphics cards, including the NVIDIA® GeForce RTX™ 40 Series. This forward-compatible approach makes it an ideal choice for users building today with tomorrow in mind.The semi-modular layout gives you the flexibility to customise cable routing based on your build, improving airflow and minimising clutter. Pre-attached essential cables reduce setup time, while detachable connectors provide additional configuration freedom. The result is a cleaner, more breathable system interior, particularly valuable for airflow-optimised cases and minimalist builds.Engineered for silence as much as performance, the Antec CSK1000 PRO features a 120mm silent fan governed by Antec’s proprietary Thermal Manager system. This intelligent fan control algorithm adjusts speed in real-time based on system load and temperature, delivering the cooling you need without excessive noise, perfect for both high-performance gaming environments and creative workstations where acoustic balance is key.Underpinning it all is CircuitShield™, Antec’s comprehensive suite of industrial-grade protections. From Over Voltage Protection (OVP) and Over Temperature Protection (OTP) to Short Circuit and Surge Protection (SCP and SIP), the Antec CSK1000 PRO actively defends both itself and your system components against irregularities and power anomalies.Compact in size yet robust in output, the 140mm chassis ensures compatibility with a wide range of enclosures, giving builders the freedom to design without compromise. Every detail—from the clean cable layout to the reinforced components—is a reflection of Antec’s commitment to quality, dependability, and purposeful engineering.For those seeking a PSU that matches technical excellence with system-level harmony, the Antec CSK1000 PRO ATX3.1 is a power solution you can build around, with assurance.FEATURES1000W continuous power delivery with high-load stabilityCertified ATX 3.1 for modern power requirements and power excursion managementPCIe 5.1 ready with 12V-2×6 (600W) connector for latest GPU standards80 PLUS® Bronze Certified (up to 90% efficiency at typical loads)Semi-modular layout for improved cable management and airflow120mm low-noise fan with intelligent thermal control (Thermal Manager)Industrial-grade CircuitShield™ protection: OVP, OCP, OTP, OPP, SCP, SIP, NLOFive-year warranty backed by Antec’s global support infrastructureSPECIFICATIONSElectrical OutputTotal Capacity: 1000W ContinuousInput Voltage: 200V–240VInput Current: Up to 6AInput Frequency: 50Hz–60HzPower Good Signal: 100–150msPower Factor Correction: Active PFCEfficiency: 80 PLUS Bronze CertifiedOperating Temperature: 0°C to 40°CConnectivity & CablingMotherboard: 1 × 24 (20 4) pinCPU: 2 × 8 (4 4) pinPCIe: 4 × 8 (6 2) pinPCIe 5.1: 1 × 16 (12 4) pin 12V-2×6 (600W)SATA: 6 × SATA connectorsMolex: 3 × 4-pin MolexCooling & AcousticsFan: 120mm silent fanControl: Thermal Manager smart fan curveAcoustic Profile: Low-noise operation under all load conditionsSafety & Protection (CircuitShield™)Over Voltage Protection (OVP)Over Current Protection (OCP)Under Voltage Protection (UVP)Over Power Protection (OPP)Over Temperature Protection (OTP)Short Circuit Protection (SCP)Surge & Inrush Protection (SIP)No Load Operation (NLO)Certifications80 PLUS Bronze 230V EUTUV, CB, CE, RCM, BIS, KC, UKCAPhysical DimensionsPSU Dimensions: 14cm (L) × 15cm (W) × 8.6cm (H)Box Dimensions: 29.65cm × 20.3cm × 13cmNet Weight: 2020gGross Weight: 2550gRegional UPC CodesEC: 0-761345-20073-8Australia: 0-761345-20074-5Great Britain: 0-761345-20075-2Thailand: 0-761345-20076-9WHAT’S IN THE  BOXAntec CSK1000 PRO ATX3.1 Power Supply Unit × 1Power Cable × 1Modular Cable Set × 1Mounting Screws × 1User Manual × 1N.B.: Your payment is encrypted and handled through a secure gateway; we never access or retain card details.
