Power supply unit PHANTEKS AMP GH 850 W, 18+10 pin ATX, Fully-Modular, 80 PLUS Gold, White

PHANTEKS AMP GH 850 W is a fully-modular ATX power supply designed for desktop systems that require stable DC output and efficient power delivery. The unit provides 850 watts of total power, 80 PLUS Gold efficiency and an 18+10 pin ATX motherboard connector. It features fully-modular cabling for flexible cable management, a 120 mm fan with hydraulic dynamic bearing for active cooling, and a white finish that suits modern PC builds. The power supply supports AC input 200–240 V at 50/60 Hz and measures 140 × 150 × 86 mm.

Advantages

The AMP GH 850 W combines high efficiency and modular convenience to simplify installation and reduce cable clutter. Its 80 PLUS Gold efficiency helps maintain lower heat generation and energy consumption under typical loads. Fully-modular connectors allow customized cable routing and improved airflow inside the case. The included 120 mm hydraulic dynamic bearing fan provides temperature-controlled active cooling and supports a hybrid fanless mode for near-silent operation at light loads. Compliance with modern ATX form factor dimensions ensures compatibility with standard PC cases.

Suitable for

• Gaming desktops and high-performance consumer PCs
• Workstations requiring stable continuous power delivery
• Custom builds where cable management and aesthetics matter
• Systems aiming for quieter operation using hybrid fanless mode

How to use

Install the power supply into a compatible ATX case following the case and motherboard manufacturer instructions. Connect the fully-modular cables only as required: attach the 18+10 pin ATX connector to the motherboard and use the supplied PCIe and peripheral cables for GPUs, storage, and other components. Ensure AC mains voltage matches the 200–240 V input specification before powering on. Monitor system temperatures and load during initial use to confirm proper airflow and fan behavior; the unit will automatically operate in hybrid fanless mode under light loads and engage the fan as temperature or load increases.

Recommendations

For reliable operation, use certified quality cables and connectors, secure all connections firmly, and allow sufficient case airflow. When building high-power systems, verify component power requirements and distribute loads across available connectors. Keep the PSU and case interior free of dust to maintain optimal cooling and long-term performance.
