1850W ATX Mining PSU – Zumax ZU-1850W
Unrivalled Power Delivery and Efficiency
The core strength lies in its robust single +12V rail design, delivering up to 144A to ensure stable hash rates in mining environments where even minor voltage drops cause rejected shares. Efficiency is handled by 80 PLUS Gold equivalent architecture, converting AC to DC with up to 90% efficiency under typical loads, reducing heat waste and electricity bills while extending capacitor lifespan.

Advanced Thermal Management
Heat is the primary enemy of electronics, and the Zumax 1850W tackles this with an industrial-grade 140mm cooling fan. The internal layout is optimised for "straight-through" airflow, utilising high-quality aluminium heatsinks that dissipate heat rapidly from primary transformers and secondary rectifiers.
1850W PSU for GPU rigs
Designed for Scale: Massive Connector Array
The ZU-1850W comes factory-equipped with 16 dedicated 6+2 Pin PCI-E connectors, allowing you to power up to 8 high-end GPUs or 16 mid-range cards directly from the source. The cables utilise high-gauge 18AWG copper wiring to handle high current without melting or overheating.

Comprehensive Safety Protections
The Zumax 1850W is built with a full suite of industrial-grade protection circuits:
- OVP (Over Voltage Protection) – prevents damage from voltage spikes.
- UVP (Under Voltage Protection) – shuts down if input voltage drops below safe threshold.
- SCP (Short Circuit Protection) – instantly cuts power if a short is detected.
- OPP (Over Power Protection) – ensures safe maximum draw.
- OCP (Over Current Protection) – monitors rails to prevent excessive current.
