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 …

Raijintek Intros High-Efficiency CPU Cooler Entitled Nemesis

Raijintek, a young but future-proof company, has recently showcased another addition to its CPU cooling solutions – the Nemesis. This is a tower-like model targeting initially overclockers and PC enthusiasts. It features 140x130x166.5 mm dimensions and weighs 1050 g. The fans of extreme cooling can enjoy all privileges of Nemesis right now, since it’s already available for pre-order in the European market for the retail price of 60 EUR.

Raijintek Nemesis consists of a copper base, five nickel-plated U-shape heatpipes, and a pair of asymmetric aluminum heatspreaders, accompanied by two fans of 140x150x25 mm standard. The fans are manipulated by powers of PWM technology, so their speed might vary from 600 RPM to 1400 RPM.

Their unified efficiency achieves 119 CFM of produced airflow; that is quite enough to cool down rather hot CPUs. Moreover, the framework allows to utilize the cooler as in active, so in passive mode when the loading is low.

Earlier Raijintek …

HIS Marvels Customers with an Overclocked Radeon HD 7850 Graphics Card

HIS has supplemented its line of Radeon HD 7850 graphics adapters with a new outstanding model, codenamed HIS 7850 iPower IceQ X² Turbo. It is primarily distinguished from the reference model by a modified design and overclocked frequencies. Another distinguishing feature is that the card will be delivered along with a brand iTurbo utility; it is called to facilitate the adjustment of all key graphics parameters and optimize its efficiency level.

HIS 7850 iPower IceQ X² Turbo is based on AMD Pitcairn Pro GPU developed on GCN architecture (28 nm technological process). Its nominal clock frequency has been increased from 860 MHz to 1000 MHz. Memory subsystem is introduced by 256-bit GDDR5 memory modules, the overall capacity of which achieves 2 GB. Their nominal clock frequency index equals to 1200 MHz, while effective frequency approximates 4800 MHz.

Cooling of all crucial components is imposed upon a brand two-slot IceQ X² system. It is characterized by a better …
