Tips

Before installation, verify that your case supports a standard ATX power supply and that your motherboard and GPU power requirements are within the 850W limit. Use the included modular cables only, and avoid daisy-chaining high-power connectors. For optimal cooling, mount the PSU with the fan facing downward if your case has a bottom vent.
