NZXT C1500 Platinum 1500W 80 PLUS Platinum Fully Modular ATX 3.1 Power Supply – Black | C1500 Platinum
The NZXT C1500 Platinum is a premium 1500W fully modular power supply designed for flagship gaming PCs and workstations. It features ATX 3.1 and PCIe 5.1 compliance, dual 12V-2x6 GPU connectors, 80 PLUS Platinum efficiency, digital power regulation, and a quiet 140mm magnetic-levitation fan.
Product Overview
The NZXT C1500 Platinum provides high-capacity, digitally controlled power for enthusiast gaming computers, professional workstations, and systems equipped with power-hungry processors and graphics cards. It delivers up to 1500W on 115–240V input, while operation on 100–115V input is rated for a maximum total output of 1300W. nzxt.com
Built to the ATX 3.1 and PCIe 5.1 standards, the C1500 Platinum is prepared for modern high-performance hardware. Two native 16-pin 12V-2x6 PCIe cables are included, alongside six conventional 6+2-pin PCIe connectors. Each 12V-2x6 connection is designed to deliver more than 600W to compatible graphics cards. nzxt.com
Its digital power platform provides precise voltage regulation with reduced ripple noise. The unit exceeds the requirements of its 80 PLUS Platinum certification, reaching up to 94% efficiency at 115V. It is also rated Cybenetics Titanium for efficiency and Cybenetics A- for noise performance. High-quality 105°C Japanese capacitors improve long-term reliability under demanding workloads.
Cooling is handled by a 140mm magnetic-levitation fan, combining strong airflow with reduced mechanical noise and extended service life. Zero-fan operation keeps the fan switched off until the system reaches approximately 60% load. The fully modular cable system allows unused cables to be removed, simplifying installation and cable management. Despite its substantial output capacity, the enclosure measures a relatively compact 150 × 86 × 180mm. nzxt.com
