Antec CSK1000 PRO PSU | 1000W 80+ Bronze Semi-Modular ATX 3.1

The Antec CSK1000 PRO ATX 3.1 is engineered for builders who need massive power without compromising on modern standards.

Delivering a continuous 1000W output, this power supply is fully optimized for the latest hardware, meeting strict Intel power delivery specifications.

The inclusion of a native 600W 12V-2×6 cable means you can power high-end graphics cards directly, ensuring stability during the intense power excursions common in modern gaming and creative workloads.

Despite its high output, the CSK1000 PRO remains efficient and quiet.

It carries an 80 PLUS Bronze certification (delivering up to 90% efficiency at typical loads) and features Antec’s proprietary Thermal Manager system.

This intelligent controller adjusts the 120mm silent fan’s speed in real-time based on load and temperature, maintaining a perfect balance between cooling and acoustics.

The semi-modular layout allows you to use only the cables you need for peripherals, keeping your case interior tidy and maximizing airflow for your other high-end components.

What It’s Good For or Fun Facts

• The “4090” Budget Solution: This is one of the most affordable ways to get a reliable 1000W unit that includes the native 16-pin cable required for flagship GPUs.

• Workstation Ready: With 1000W of overhead, this unit is perfect for AI rendering, deep learning, or multi-GPU setups where power stability is non-negotiable.

• Compact Powerhouse: Even with 1000W of juice, it features a compact 140mm depth, fitting into almost any standard ATX chassis.

• Fun Fact: The “PRO” designation in the CSK series indicates it uses higher-grade internal components compared to standard bronze units to handle the 1000W continuous load safely.

Good to Knows

• ATX 3.1 Compliance: This is the latest standard, designed to handle power spikes up to 2x the PSU’s rated wattage for short bursts, preventing sudden system crashes.

• CircuitShield™ Protection: Includes 8 layers of industrial-grade protection (OVP, OCP, UVP, SCP, OPP, OTP, SIP, NLO) to keep your expensive hardware safe from South African power grid anomalies.

• Semi-Modular: The critical motherboard and CPU cables are fixed, while the GPU and storage cables are modular, giving you the best of both worlds for build speed and neatness.

• Warranty: Supported by a robust 5-year warranty for long-term peace of mind.
