NZXT C1500 80 PLUS Platinum Fully Modular ATX 3.1 1500W Low Noise Power Supply

Enterprise-Class 1500W Power for Extreme Gaming Systems

The NZXT C1500 Platinum ATX 3.1 is a flagship power supply engineered for ultra-high-performance gaming PCs and workstation builds. Delivering a massive 1500 watts of continuous power, it is ideal for systems equipped with flagship GPUs such as the NVIDIA GeForce RTX 5090 and heavily overclocked CPUs. Built to the latest ATX 3.1 and PCIe 5.1 standards, it is designed to handle the power demands of current and future hardware generations with exceptional stability and efficiency.

Platinum Efficiency and Low-Noise Operation

Certified with 80 PLUS Platinum efficiency, the C1500 exceeds 94% efficiency at typical loads, reducing wasted energy and minimizing heat output. Digital power regulation ensures highly accurate voltage delivery with low ripple and improved overall system stability. Cooling is handled by a premium 140mm magnetic levitation fan, which offers long lifespan, strong airflow, and quiet operation under varying loads. The unit also carries Cybenetics Titanium efficiency and A- noise certifications, reinforcing its focus on both performance and acoustics.

Fully Modular Design with Premium Components

The fully modular cable design allows builders to install only the cables they need, improving airflow and simplifying cable management. The PSU includes two native 12V-2x6 connectors, each capable of delivering more than 600W to next-generation graphics cards without adapters. Internally, it uses 105°C Japanese capacitors and comprehensive protection circuits including OVP, UVP, SCP, OTP, OPP, and OCP for long-term reliability. Community feedback has generally been positive, with users reporting stable operation and very quiet performance in demanding RTX 5090 systems.
