KHACHIMO DPS-850AB-12A 850W ATX Power Supply

850W ATX Supply for Dual-GPU Builds

This 850-watt ATX power supply targets builders running a pair of 2080-class graphics cards. Gold-certified efficiency keeps heat and electricity draw low under heavy loads. The resonant LLC topology with DC-to-DC conversion delivers clean, stable rails for demanding multi-GPU configurations. Modern Standby support enables near-instant wake from sleep states.

Gold Efficiency and ATX Cable Constraints

The 80 PLUS Gold rating guarantees at least 80 percent efficiency at typical loads, reducing waste heat inside the case. Fixed ATX cabling means every connector is permanently attached, so unused leads must be routed and tucked away during assembly. Cable lengths follow the ATX specification, limiting reach in oversized or non-standard chassis layouts. Builders should verify connector counts against their specific GPU and motherboard requirements before ordering.

Standard ATX Fit with Fixed Wiring

The unit fits any standard ATX mounting pattern using four rear screws, requiring no special brackets or adapters. Fixed cables simplify the first connection but can complicate tight routing behind motherboard trays. Zero RPM fan mode eliminates noise at low load, though the fan will spin up under sustained multi-GPU stress. Ensure the rear exhaust path remains clear so hot air exits the case efficiently.
