Chieftec Navitas Gets a 450-Watt Update

First launched in 2013, Chieftec Navitas series of PSUs included five high-efficiency models of up to 1250 W power. This year the company has introduced four new editions to the family which are characterized by low power: 450 W, 550 W, 650 W, and 750 W. This update is called to satisfy the needs of unpretentious customers who require stability rather than records.



New Chieftec Navitas power supply units come equipped with a single +12V bus that covers 100% power. Hence, it’s possible to integrate the models into the latest system configurations. All of them correspond to 80 Plus Gold standard, achieving up to 87% efficiency in a wide range of operational conditions.


Their other peculiarities involve a fully modular cable system, the availability of a low-noise 120 mm fan, the support for Active PFC technology and all known protection features (i.e. OPP, OTP, UVP, OVP, SCP).


To continue, Chieftec Navitas GPM-450S ensures 450-watt power on +12V rail & up to …
