ANTEC NE850W 80+ Gold Fully Modular Power Supply (850 W)

The ANTEC NE850W is a fully modular ATX 12V power supply rated at 850 watts and certified to the 80 Plus Gold efficiency standard, meaning it delivers at least 87% efficiency at 50% load under typical operating conditions. This certification helps reduce wasted heat and lowers electricity consumption compared to lower-tier 80 Plus Bronze or non-certified units. The NE850W is built on ANTEC's NeoECO Gold platform and employs a PhaseWave LLC topology combined with a DC-to-DC conversion stage. This design approach helps regulate voltage more precisely across the 12V, 5V, and 3.3V rails, which benefits system stability during demanding workloads such as gaming, content creation, or sustained CPU and GPU loads. A 120 mm fan handles thermal management. The unit supports a Zero RPM operating mode, which keeps the fan fully stopped at low-to-moderate loads, resulting in near-silent operation during everyday tasks and light gaming. The fan only spins up when internal temperatures or power draw genuinely require active cooling. Long-term reliability is supported by the use of Japanese heavy-duty electrolytic capacitors, which are selected for their rated temperature tolerance and longevity compared to generic alternatives. ANTEC backs this unit with a 7-year warranty, reflecting confidence in the build quality. Being fully modular, every cable—including the 24-pin ATX motherboard connector—detaches completely. This simplifies routing, improves airflow inside the chassis, and reduces clutter for cleaner builds.
