Built for the Builds That Don’t Compromise

The Antec CSK1000 PRO is the electrical foundation your high-performance rig deserves. Whether you’re deep in a gaming marathon, rendering complex 3D scenes, or running demanding productivity workloads, 1000W of continuous, stable power keeps everything running without hesitation — even under peak load.

Ready for the Next Generation of GPUs

With full ATX 3.1 certification and a dedicated PCIe 5.1 12V-2×6 connector capable of delivering up to 600W, the CSK1000 PRO is built to support the latest NVIDIA® GeForce RTX™ 40 Series cards and whatever comes next — making it the last PSU upgrade you’ll need to worry about for a long time.

Clean Builds, Quiet Operation

The semi-modular design lets you route only the cables you need, cutting clutter and improving airflow inside your case. Pair that with a 120mm fan governed by Antec’s intelligent Thermal Manager system, and you get a PSU that stays whisper-quiet unless your system truly demands otherwise.

Protected From Every Angle

Antec’s CircuitShield™ suite wraps your entire system in industrial-grade protection — guarding against over-voltage, over-current, over-temperature, short circuits, and power surges. Backed by a five-year warranty, this is a power supply you can build around with confidence.
