Meet Self-Purified D.F.Vegas Fans from Enermax

Enermax has enlarged its lineup of fans with D.F.Vegas series. The series consists of two models: the D.F.Vegas & the D.F.Vegas Duo. The key differentiation between the two solutions lies in the current intensity as well as LED backlights. The first new-comer is equipped with 12 blue diodes, while the second model houses 12 red and 12 green diodes.

Enermax D.F.Vegas fans boast the implementation of self-purification technology – Dust Free Rotation (DFR). During the first ten seconds of operation the fan rotates contrary clockwise and then returns to standard rotational mode. That is how dust and litter is removed from the blades. If there is a need in manual cleansing, the blades can be easily detached.

Both fans are designed on Twister Bearing with MTBF index of 160 thousand hours. The frame accommodates a single 4-pin connector which supports PWM technology. Hence, it’s possible to limit the maximal rotation speed by 1100/1300/1500 RPM by means of a dedicated …

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 …
