Powering Next-Gen GPUs with PCIe 5.1
The Antec CSK1000 PRO includes a dedicated 12V-2×6 connector capable of delivering up to 600W directly to PCIe 5.1 GPUs. This ensures stable, uninterrupted power delivery for the latest high-end graphics cards, eliminating the need for dongles or adapters. The single +12V rail provides 83.3A of clean, reliable current for demanding multi-GPU setups.
Semi-Modular Design for Cleaner Builds
With a semi-modular layout, the CSK1000 PRO keeps essential cables permanently attached while allowing non-essential cables to be detached. This reduces cable clutter inside your case, improves airflow, and makes installation faster. The compact 140mm depth fits easily into most ATX cases without sacrificing power delivery.
Quiet Cooling with Intelligent Thermal Management
Equipped with a 120mm silent fan, the PSU uses intelligent speed control to balance cooling performance with noise levels. Under typical loads, the fan remains quiet while maintaining optimal temperatures. The CircuitShield protection suite adds over-voltage, over-current, over-temperature, and surge protection for long-term reliability.
Compact Size, Powerful Performance
Despite its 1000W capacity, the Antec CSK1000 PRO maintains a compact form factor at just 140 × 150 × 86mm and weighs approximately 2.02kg. This makes it suitable for both standard and smaller ATX cases where space is at a premium. The 80 PLUS Bronze certification ensures up to 90% efficiency under typical loads, reducing heat and electricity waste.
