2. 80 Plus - Wikipedia

   en.wikipedia.org/wiki/80_Plus

   To qualify for 80 Plus, a power supply must achieve at least 80% efficiency at three specified loads (20%, 50% and 100% of maximum rated power). However, 80 Plus supplies may still be less than 80% efficient at lower loads. For instance, an 80 Plus, 520 watt supply could still be 70% or less efficient at 60 watts (a typical idle power for a ...

   Alienware M15 R2 (discontinued) – 2019 thin and light gaming laptop. 1080p standard display and 60 Hz Ultra HD 4K display, 144 Hz IPS 1080p, and 240 Hz IPS 1080p display also available, as well as a Nvidia GeForce 20 series with up to a RTX 2080 Max-Q, 9th gen Intel CPU.

4. Power supply unit (computer) - Wikipedia

   en.wikipedia.org/wiki/Power_supply_unit_(computer)

   For example, a 900-watt power supply with the 80 Plus Silver efficiency rating (which means that such a power supply is designed to be at least 85% efficient for loads above 180 W) may only be 73% efficient when the load is lower than 100 W, which is a typical idle power for a desktop computer. Thus, for a 100 W load, losses for this supply ...

5. Airwatt - Wikipedia

   en.wikipedia.org/wiki/Airwatt

   Unlike electrical power (measured in watts), which includes energy lost due to inefficiencies, the airwatt directly reflects the actual airflow and suction power. Therefore, two vacuum cleaners with the same airwattage will have essentially the same suction, whereas devices with the same electrical wattage might vary significantly in efficiency ...
