Efficiency at low cost, that s the reason, why the new A-90 series from CHIEFTEC has been invented. The three high performance PSU s cover with their nominal power output of 550 watts 750 watts all kinds of usage possibilities. With a fixed output voltage of 230 V, this power supply series is especially made for cost-aware computer consumers. The PSU s have an efficiency of >90% and thus meet the 80plus gold requirements.
