Fully compliant with the latest ATX 3.1 and PCIe 5.1 standards, CSK1000 PRO includes a dedicated PCIe 5.1 12V-2x6 (600W) GPU cable, making it ready for NVIDIA GeForce RTX 40 Series and future high-draw graphics cards without adapters. A pair of 8-pin (4+4) EPS CPU connectors supports high-end motherboards and multi-core CPUs, while 4 x 8-pin (6+2) PCIe connectors handle multiple GPUs or power-hungry add-in cards.

The unit uses Antec’s CircuitShield™ suite of industrial-grade protections, including OCP, OVP, UVP, SCP, OPP, OTP, SIP and NLO, to safeguard your system against unstable power and fault conditions. A 120mm silent fan provides smart, temperature-controlled cooling to keep noise levels low during light loads while still handling heavy gaming and rendering sessions.

With a semi-modular design, only the essential cables are fixed, and the rest are detachable, helping reduce cable clutter and improve airflow inside the case. Operating on 200–240V AC with active PFC and backed by a 5-year warranty, the CSK1000 PRO GB offers an excellent price-to-performance ratio for high-wattage ATX 3.1 builds that don’t need a full Gold/Platinum unit but still demand reliability and modern standards.
