Power Module Chieftec A80 650W Review

The requirements of customers towards contemporary power modules are quite tough. They should own good performance characteristics and high coefficient of efficiency level, as well as 80Plus marker. The latter speaks about quality and ability to satisfy the needs of any PC. However, all PSU are classified according to different criteria, so one can find appropriate product even without 80Plus standards. The compliance with those standards is realized on 115V and 230V conditions but there are a number of standards applied to 220V-240V. Power module Chieftec A80 650W doesn’t belong to the army of 80Plus products, though can boast outstanding performance and efficiency. It is primarily targeted at the segment of affordable PSU solutions.
