Nzxt C1500 ATX 3.1 – 1500 Watt 80 Plus Platinum Fully Modular SMPS

The NZXT C1500 Platinum is a 1500-watt fully modular power supply built to meet the demands of today’s most power-hungry PC configurations. Compliant with the ATX12V v3.1 and EPS12V v2.92 standards, it is designed to handle current and next-generation high-performance GPUs and CPUs without compromise. Two included 16-pin (12+4) 12V-2×6 PCIe 5.1 cables each support GPU loads exceeding 600 watts, making this unit an appropriate choice for dual-GPU workstations or multi-rail high-draw systems. Six additional 6+2-pin PCIe connectors provide further flexibility for complex builds. Digital power control enables precise voltage regulation across all rails. The single +12V rail delivers up to 125A (1500W), while the 3.3V and 5V combined rail provides up to 120W. This architecture reduces ripple noise and maintains stable output under variable loads. The C1500 carries an 80 Plus Platinum certification, achieving 92% efficiency at 10% load, 94% at 20% load, 93.8% at 50% load, and 90.8% at full load — all measured at 115Vac. The source also notes a Cybenetics Titanium efficiency rating claim, though independent verification of that specific rating is recommended before using it in marketing materials. A 140mm Magnetic Levitation Bearing (ML) fan manages thermal output. The magnetic levitation design reduces mechanical friction, with a rated maximum noise level of 41.0 dBA and airflow of approximately 125 CFM. The fan measures 140 x 140 x 25 mm and spins at up to 2,500 RPM (±10%). The fully modular cable system means only the cables you need are connected, reducing clutter and improving airflow inside the case. The unit’s compact 180mm depth (150mm wide, 86mm tall) fits most mid-tower and full-tower enclosures. Cables are nylon-sleeved throughout: the 24-pin ATX runs 600mm, CPU cables reach 700mm, and PCIe cables extend 650mm. Protections include OVP, UVP, SCP, OTP, OPP, and OCP. Active power factor correction is rated at 0.99. MTBF is rated at 100,000 hours, and the unit operates from 0°C to 50°C. The chassis is constructed from steel, PCB, and plastic.
