CES 2016: Cooler Master’s MasterWatt Connected Digital PSU Almost Ready
 

As one gets older, or designs PCs for certain users in mind, how much power is being consumed is a key metric. The easiest piece of equipment to use is software, which gives a value but is known for being abstracted from the true value and often wrong due to bad assumptions. The next step up is using a cheap $20 or less wall meter, which most people do, although those readings are skewed by the efficiency of the power supply or assume a constant voltage from the mains. The best reading is at source, and actually probing the component being tested, although that requires digging in with voltage probes on the hardware level. There should be a middle ground, and we saw it back at CES 2015 with Cooler Master.
