Description
xIn today’s fast-moving world of PC hardware, power delivery isn’t just a technical detail — it’s the backbone of system stability, performance, and longevity. The Antec NeoECO Gold Modular 850W PSU brings this to life with precision engineering, modern design, and over 35 years of trusted innovation in performance computing.
Designed for gamers and system builders who demand more, the Antec NeoECO Gold 850W PSU combines cutting-edge performance with modular flexibility. At its heart is a high-efficiency, fully modular power platform built to fuel the latest high-performance CPUs and PCIe 5.0 GPUs, while keeping thermals and acoustics optimised.
With 80 PLUS® Gold certification, it delivers up to 92% efficiency under typical loads, translating to lower heat, reduced energy waste, and better overall system performance. It's powerful single +12V rail delivers over 99% of the PSU’s total output, ensuring stable, uninterrupted power for intensive tasks like gaming, rendering, and content creation.
Built on Antec’s PhaseWave™ design (a Half-Bridge LLC topology with DC-to-DC conversion), this PSU offers consistently clean, stable power. Synchronous rectification boosts reliability under fluctuating loads, while the included 12VHPWR cable ensures full compatibility with NVIDIA RTX 40 Series GPUs and PCIe Gen 5.0 — no adapters needed.
Cooling is intelligently managed by a 120mm Fluid Dynamic Bearing fan. Under light loads, Zero RPM mode keeps the fan off for silent operation. As demand increases, onboard thermal sensors automatically adjust fan speed, striking the ideal balance between cooling and noise.
Inside, the Antec NeoECO Gold 850W PSU is built with premium all-Japanese capacitors, delivering tighter voltage control, lower ripple, and outstanding durability — even under sustained load or high-heat conditions.
The fully modular cable system keeps builds clean and airflow efficient. Only plug in what you need. A forward-compatible 28(18+10) pin MBU connector supports next-gen motherboard standards, making future upgrades a breeze.
Antec’s CircuitShield™ safety suite provides full protection — including overcurrent, overvoltage, short circuit, inrush surge, and more — for complete peace of mind, whether you’re powering a pro-grade workstation or a high-end gaming setup.
All this is packed into a compact, matte-black chassis and backed by Antec’s 7-year warranty. The NeoECO Gold 850W isn’t just a PSU — it’s a long-term investment in stability, performance, and evolution.
