1800 W ATX Mining Power Supply

The TOPOWER TOP-1800WM1 delivers 1800 W of continuous power for ATX mining rigs that run eight graphics cards. It accepts AC input from 100 to 240 V and uses active PFC with a single +12 V rail. The unit measures 165 mm in length and includes a 20+4 pin main connector.

Sixteen PCI-E 6+2 Pin Connectors

Sixteen PCI-E 6+2 pin connectors provide the sole power interface for the graphics cards. Eight SATA power connectors are available for risers or storage drives. The non-modular cable set fixes every lead in place for a permanent installation.

Single Fan With Active PFC

One fan handles airflow while the active PFC stage maintains efficiency above 85 percent. Over-voltage and overload protection circuits guard the hardware during sustained loads. The power supply operates across the full 100 to 240 V input range without manual switching.
