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 …

NZXT to Launch a New Line of Powerful PSUs

Developers from NZXT decided to revive a series of prime power supply units, codenamed HALE90, launched in 2010 by designing a new line of powerful units. The line has been entitled HALE90 V2 and includes three models of 850W, 1000W, and 1200W power. All three models are notable by the availability of 80Plus Gold certificate that verifies their high-performance and reliability.

Unlike the majority of similar products, HALE90 V2 are housed in casings of white color with black insertions that add some elegance to the overall design. The units are characterized by a totally modular cabling (including 24-pin ATX connector); this is called to dramatically simplify the accomplishment of individual wire sheath on modding. One of the peculiarities of this PSU line is rigid connection of the mainboard with the cable board, while the majority of rival PSUs employ flexible wires.

Voltage 12V generation is realized by means of a single rail. The platform is developed according to …

Meeting New Gaming Memory Kits AMD Radeon RG2133

A couple of days ago AMD introduced a new series of DDR3 memory kits within the boundaries of AMD Unified Gaming Strategy development. Codenamed AMD Radeon RG2133, the new-comers are available in two- and four-channel kits, the overall capacity of which equals to 16 GB and 32 GB correspondingly. The most striking feature is that they can be employed as on AMD, so on Intel platforms, supporting AMD AMP and Intel XMP technologies for improved settings optimization.

The other peculiarity is that these memory kits run at 2133 MHz frequency. On such conditions there is always a chance to dramatically increase the system performance up to 22% (with APU AMD A10 on board). Herewith, voltage index equals to 1.65 V, while latency index looks the following way: 10-11-11-30. Memory chips are cooled down by the forces of a high-quality aluminum heatspreader. Its design is called to ensure a stable operation in response to the increased frequencies.
