ATX 3.1 POWER FOR MODERN BUILDS: Built to the Intel ATX 3.1 standard with a PCIe 5.1 interface, this fully modular power supply is designed to manage changing system loads while keeping unused cables out of the build.
80 PLUS GOLD EFFICIENCY: 80 PLUS Gold certification supports efficient power conversion under typical loads. A 100240V full-range AC input makes the KN Series suitable for compatible mains environments; use the included regional power cord.
JAPANESE 105°C CAPACITORS: A Japanese bulk capacitor and 105°C-rated capacitors support stable long-term operation. The 120mm hydraulic-bearing fan uses thermal control to balance cooling and operating noise as load changes.
NATIVE 12V-2X6 GPU CONNECTION: The included 12V-2x6 cable provides a direct PSU-to-GPU connection for compatible graphics cards. Insert both ends fully, keep the plug seated, and avoid tight bends near the connector.
CHECK THE INCLUDED CABLES BEFORE ORDERING: Includes one 24-pin motherboard cable, two CPU cables, 3 PCIe 6+2-pin cables, 2 SATA cable sets, one 12V-2x6 cable, and the AC power cord. Use only the modular cables supplied with this PSU.

Power a clean, modern desktop build with the PCCOOLER KN Series. Designed to the Intel ATX 3.1 standard, each model combines a fully modular layout, PCIe 5.1 interface, native 12V-2x6 cable, and 80 PLUS Gold efficiency in a compact 150 × 140 × 86mm chassis. Japanese 105°C capacitors, an active PFC + half-bridge SRC LLC + DC-to-DC topology, and seven circuit protectionsOVP, UVP, SCP, OPP, OCP, OTP, and SPDsupport stable everyday operation. A thermally controlled 120mm hydraulic-bearing fan adjusts cooling as load changes. Flexible embossed modular cables help simplify routing. Before ordering, compare the cable list for your selected wattage with the motherboard, CPU, GPU, storage devices, and accessories in your build. Connect only the cables supplied with this power supply; modular PSU cables are not universally interchangeable. For a compatible graphics card, connect the included 12V-2x6 cable directly from the power supply to the GPU. Seat both connectors completely and avoid a tight bend immediately beside the plug. Choose total PSU wattage according to the full system configuration and component manufacturer guidance.
