Chieftec Showcases Five New PSUs from Navitas Series

Chieftec, one of the largest German hardware manufacturers, has recently introduced a new series of power supply units, codenamed Navitas. The series is represented by 5 models: GPM-650C with 650W nominal power, GPM-750C with 750W nominal power, GPM-850C with 850W nominal power, GPM-1000C with 1000W nominal power, and GPM-1250C with 1250W nominal power correspondingly. All the products have won 80Plus Gold certificate, due to more than 90% efficiency in the high workloads.

Chieftec Navitas PSUs correspond to ATX12V v2.3 standard and support Intel Core 4th gen. processors that require little current strength on +12V rail in sleep mode. The models also support active power-factor correction option to provide for the maximal stability during operation. They are equipped with a composite cable system and a single +12V rail, estimated for the maximal current from 54 A to 104 A (this index depends on the unit’s power).

All five units are cooled down by 140 mm fans with PWM …
