Over Power Protection and Max Wattage
Power supplies often quote as having various protection mechanisms such and the most important of these is Over Power Protection. In our testing we crank up the power draw until the power supply either shuts down (meaning the OPP mechanism is present and working) or blows up (meaning it is either not present or not working). We then note the maximum power consumption before the power supply shut down (or blew up).
Not the biggest result ever, but certainly enough headroom to deal with any power spikes. This being a well-made unit, I wouldn’t be surprised to see it run past 600W all day long, ever day, without any issue; that’s the quality you get with a unit like this.
