Efficiency Normal, Light & Super-Light Loads
The HX1500i is efficient at normal and ultra-light loads. However, I would like to see a slightly higher efficiency in the load range of 20-80 W.
Average Efficiency 5VSB
The 5VSB rail is highly efficient.
Vampire Power
The power required by a power supply in standby mode is called vampire or phantom power because it is consumed without the power supply doing anything. This current is mostly lost via the 5VSB circuit of the power supply. This value is pleasantly low in the Corsair HX1500i.
Average efficiency
The average efficiency is at the right level for a Platinum-rated device.
PFC (Power Factor Correction)
A power factor correction filter increases the power factor reduced by the distortion reactive power, because it reduces the proportion of disturbing harmonics and thus also the mains load. The APFC converter of the Corsair HX1500i could definitely be tuned even better to deliver higher PF values at 230V input voltage.
