NZXT C1500 1500W 80+ Platinum Fully Modular ATX 3.1 Power Supply

The NZXT C1500 1500W 80+ Platinum Fully Modular ATX 3.1 Power Supply (model PA-5P1BB-UK) is engineered for demanding, high-performance PC builds that require stable, clean, and abundant power delivery. Compliant with ATX12V v3.1 and EPS12V v2.92 standards, this power supply is ready for current and next-generation hardware, including power-intensive discrete GPUs that draw well in excess of 600 watts. At its core, the C1500 uses digital power control to deliver precise voltage regulation across all rails, reducing ripple noise and improving overall system stability. The unit is rated 80 Plus Platinum, with independently measured efficiency figures of 92% at 10% load, 94% at 20% load, 93.8% at 50% load, and 90.8% at 100% load — all measured at 115Vac. Additionally, the C1500 holds Cybenetics Titanium efficiency and Cybenetics A- noise level ratings, reflecting performance beyond the standard Platinum threshold. Two 16-pin (12+4) 12V-2×6 PCIe 5.1 cables are included, each on a 650mm nylon-sleeved run, enabling direct high-wattage connections to flagship GPUs without the need for adapters. The connector suite is extensive: one 24-pin ATX (600mm), one 4+4-pin CPU (700mm), one 8-pin CPU (700mm), six 6+2-pin PCIe (650mm), 12 SATA connectors, and four peripheral connectors, all fully modular so unused cables stay out of the chassis. Cooling is handled by a 140mm magnetic levitation bearing fan (140 x 140 x 25 mm) capable of up to 125 CFM airflow at a maximum rated speed of 2,500 RPM and a maximum noise level of 41.0 dBA. The magnetic levitation bearing reduces friction, contributing to an MTBF rating of 100,000 hours. Internal components include all 105°C-rated Japanese capacitors. The power supply incorporates six protection circuits: overvoltage (OVP), undervoltage (UVP), short circuit (SCP), over-temperature (OTP), overpower (OPP), and overcurrent (OCP). Active power factor correction reaches 0.99. The compact 180mm depth (150mm wide × 86mm tall × 180mm deep) preserves case volume. The unit operates across a 100–240Vac input range (15A–9A, 50–60 Hz) and is backed by a 10-year manufacturer warranty.
