In today's fast-moving world of PC hardware, power delivery isn't just atechnical detail it's the backbone of system stability, performance, andlongevity. The Antec NeoECO Gold Modular 850W PSU brings this to life withprecision engineering, modern design, and over 35 years of trusted innovation inperformance computing.Designed for gamers and system builders who demand more, the Antec NeoECO Gold850W PSU combines cutting-edge performance with modular flexibility. At itsheart is a high-efficiency, fully modular power platform built to fuel thelatest high-performance CPUs and PCIe 5.0 GPUs, while keeping thermals andacoustics optimised.With 80 PLUS® Gold certification, it delivers up to 92% efficiency under typicalloads, translating to lower heat, reduced energy waste, and better overallsystem performance. It's powerful single +12V rail delivers over 99% of thePSU's total output, ensuring stable, uninterrupted power for intensive taskslike gaming, rendering, and content creation.Built on Antec's PhaseWave design (a Half-Bridge LLC topology with DC-to-DCconversion), this PSU offers consistently clean, stable power. Synchronousrectification boosts reliability under fluctuating loads, while the included12VHPWR cable ensures full compatibility with NVIDIA RTX 40 Series GPUs and PCIeGen 5.0 no adapters needed.Cooling is intelligently managed by a 120mm Fluid Dynamic Bearing fan. Underlight loads, Zero RPM mode keeps the fan off for silent operation. As demandincreases, onboard thermal sensors automatically adjust fan speed, striking theideal balance between cooling and noise.Inside, the Antec NeoECO Gold 850W PSU is built with premium all-Japanesecapacitors, delivering tighter voltage control, lower ripple, and outstandingdurability even under sustained load or high-heat conditions.The fully modular cable system keeps builds clean and airflow efficient. Onlyplug in what you need. A forward-compatible 28(18+10) pin MBU connector supportsnext-gen motherboard standards, making future upgrades a breeze.Antec's CircuitShield safety suite provides full protection includingovercurrent, overvoltage, short circuit, inrush surge, and more for completepeace of mind, whether you're powering a pro-grade workstation or a high-endgaming setup.All this is packed into a compact, matte-black chassis and backed by Antec's7-year warranty. The NeoECO Gold 850W isn't just a PSU it's a long-terminvestment in stability, performance, and evolution.FEATURES * 850W continuous power output with over 99% on a resolute +12V rail * 80 PLUS® Gold certified: Up to 92% efficiency under typical load * PCIe 5.0 Ready: Includes native 12VHPWR cable for RTX 40 Series GPUs * Half-Bridge LLC + DC-DC PhaseWave Design with synchronous rectification * Silent 120mm FDB fan with Zero RPM mode for low-noise operation * Fully modular design for best airflow and cable customisation * High-grade Japanese capacitors ensure reliability and low ripple * CircuitShield protection suite: OCP, OVP, UVP, SCP, OPP, OTP, SIP, NLO * Compact design for easy integration in mid and full tower chassis * Backed by Antec's trusted 7-year warrantySPECIFICATIONSPower Output * Total Output: 850W Continuous * Efficiency Rating: 80 PLUS® Gold (up to 92%) * +12V Rail: >99% of total output (single rail) * Active PFC: Yes * Topology: Half-Bridge LLC + DC-DC * PCIe 5.0 Support: Yes (native 12VHPWR included)Cooling & Acoustics * Fan Type: 120mm Silent Fluid Dynamic Bearing * Zero RPM Mode: Yes (fan stays off under low loads) * Thermal Control: Smart fan curve based on internal sensorsCabling & Connectors * Type: Fully Modular * MB: 1 × 24(20+4) Pin * CPU: 2 × 8(4+4) Pin EPS 12V * GPU: 6 × 8(6+2) Pin PCIe, 1 × 16(12+4) Pin 12VHPWR * Peripherals: 10 × SATA, 5 × Molex, 1 × FDD * MBU: 28(18+10) pin future-ready socketElectrical Specifications * Input Voltage: 100240 VAC * Input Current: 10A Max * Input Frequency: 5060Hz * Power Good Signal: 100500ms * Operating Temperature: 0°C 40°CProtection & Compliance * CircuitShield: OCP / OVP / UVP / SCP / OPP / OTP / SIP / NLO * Certifications: cTUVus / TUV / CB / RCM / CE / FCC / BIS / BSMI / KC / UKCA / ICESPhysical Dimensions * Size: 15cm (L) x 14cm (W) x 8.6cm (H) * Net Weight: 1380g * Gross Weight: 2710gWHAT'S IN THE BOX * Antec NeoECO Gold Modular 850W Power Supply Unit ×1 * Full modular cable kit ×1 * Power cable ×1 * Installation screws ×1 * Quick installation guide ×1
