KHACHIMO 630W Switching Power Supply GW-ERP2U600 (90+)

630W ATX Power Supply

This ATX power supply delivers up to 630 watts of continuous power for desktop builds. It is suited for system integrators and hobbyists assembling workstations or mid-range gaming PCs. The unit is supplied new and has been tested working before shipment. It targets builders who need a straightforward power source without modular cabling.

Sustained load behaviour

The 90+ marking indicates the unit maintains at least 90 percent efficiency at typical loads, reducing waste heat during extended operation. Stable output rails help components run consistently through long rendering or compute sessions. Thermal performance scales with the installed chassis airflow rather than a fixed fan curve. Builders seeking fanless or semi-passive designs should look elsewhere.

ATX interface limits

The ATX form factor fits standard desktop cases and motherboards using 24-pin and 4/8-pin CPU connectors. Maximum combined output is capped at 600 watts on the labelled rails, so systems drawing near 630 watts may exceed safe margins. High-end multi-GPU configurations or dense storage arrays will require a higher-capacity unit. Cable lengths follow the baseline ATX specification for mid-tower layouts.
