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 …

AMD Adds Three New Mobile APUs to Kabini Series

AMD has replenished its mobile APU line with three new models of AMD Kabini series: E2-3800, E1-2200 and A4-5100. The triple is developed on Jaguar microarchitecture (28 nm) with SoC design. Needless to say that the new-comers are destined to be incorporated within hand-held mobile devices, such as entry-level laptops and tablets. All of the models are housed in BGA 769 socket cases, thus the customers might expect their market appearance within ready devices.



SoC design stipulates the integration of a one-channel DDR3 controller with the support for two memory modules. In addition, it allows for the enabling of SD, USB 3.0, HD Audio, PCI Express 2.0, LPC, and SATA 6 Gb/sec interfaces. More details about each model are provided below.


AMD E2-3800


This model features 4 cores, operating at 1300 MHz clock frequency. It employs an onboard Radeon HD 8280 graphics chip that runs at 450 MHz. DDR3 controller supports the installation of modules of up to 1600 MHz frequency. The …

Spire Showcases New Cylinder-Shaped Swirl IV CPU Cooler

Spire is going to release a new extraordinary cooling solution: a cylinder-shaped CPU cooler, entitled Swirl IV. It is targeting Intel processors for Socket 2011/1366/115x/775 and AMD FM1/FM2/AM2/AM3 platforms with the maximum TDP level of 130 W. The new-comer has received RoHS and CE certification that proves its environmentally-friendly nature. An official release is postponed to January 2015.



Spire Swirl IV features 131x125x62 mm dimensions and weighs 690 g. Its heatsink consists of 45 aluminum fins, pierced by three copper zinc-plated U-shaped heatpipes (8 mm). Inside the heatsink one can find a 60 mm fan with blue LED backlit. Its rotational speed is controlled by PWM technology so that the blades could run between 600 RPM up to 2000 RPM.


The fan is equipped with a slide bearing, estimated for 50.000 hours of fool-proof operation. It is powered by means of a 4-pin connector, ensuring up to 83.12 CFM airflow at 26 dB noise. Besides, at the highest rotational speed the …
