Product information

Description

ANTEC CSK850 Pro ATX3.1 850W is a desktop power supply designed to deliver stable mains-to-system power for gaming PCs and workstations. Built to the ATX3.1 form factor, this 850W unit supports modern desktop components and provides continuous power delivery suitable for high-load configurations. The design focuses on reliable voltage regulation and cooling to maintain steady operation under sustained CPU and GPU demand.

Advantages

The ANTEC CSK850 Pro offers an 850W rated output within the ATX3.1 standard, providing compatibility with contemporary motherboards and power delivery requirements. The unit emphasizes consistent voltage regulation, efficient power conversion and thermal management to reduce the risk of performance throttling in demanding workloads. Cable connectivity and connector types are arranged to support multiple PCIe and motherboard power inputs common in high-performance systems.

Suitable for

  • Gaming desktops with mid-to-high power GPUs
  • Workstations running rendering or simulation tasks
  • PC builds that require ATX3.1 compatibility
  • Systems with multiple drives and expansion cards

Key specifications

  • Form factor: ATX3.1 desktop power supply
  • Nominal output power: 850 W
  • Input: AC mains voltage range suitable for desktop use (auto-switching)
  • Efficiency class: designed for efficient power conversion (meets modern PSU efficiency expectations)
  • Cooling: active fan cooling optimized for continuous load
  • Protection features: over-voltage, under-voltage, over-current and short-circuit protections
  • Connectors: multiple PCIe connectors and standard motherboard power connectors to support high-performance components

How to use

Install the ANTEC CSK850 Pro in a compatible ATX3.1 chassis following the motherboard and case manufacturer guidance. Connect the main 24‑pin motherboard cable, CPU power cable(s), and required PCIe power connectors to the graphics card(s). Attach SATA and peripheral power cables to storage devices and other internal components. Ensure all connections are secure, set the PSU switch (if present) to the correct mains position, and verify that the system is properly grounded before powering on.

Usage recommendations

Place the power supply in a case with sufficient airflow, keep intake and exhaust paths clear of obstructions, and use a surge protector or UPS for added mains protection. For systems with high sustained loads, monitor operating temperatures and consider periodic dust cleaning to maintain cooling performance. Confirm that the total system power draw stays within the 850W rating, allowing headroom for peak loads and future upgrades.
