SinoVoip’s recommendation to use a more powerful PSU than 12V/2A when the BE14 card is installed might seem excessive. In my own testing the power consumption of this setup was only 12 W under high load. But when I tried to use it for an extended period of time powered by a 12V/2.5A brick, the router would randomly restart every few hours under very minor load leaving no kernel crash logs, so I figured it was some sort of hardware problem. Now that I’ve switched to a 12V/7A PSU it’s been a full day without a restart. So, yeah, don’t skimp on the power supply.
