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 …

AMD continues to reveal secrets regarding its Zen-based novelties. This time we are speaking about chipsets for the enterprise market under the Naples code name.



The first of the Naples CPUs mentioned encompasses 8 CCX computing units (CPU Complex) with each of them possessing 4 cores. All in all, there are 32 cores, and 64 threads are processed simultaneously. The chipset includes an embedded DDR4 memory 8 channel controller and a module of 64 64 PCI-Express 3.0 lines. The max RAM capacity is 2 TB. On top of everything AMD Infinity Fabric allows to form dual-processor systems and, thus, double all aforecited rates.


The AMD Co. is going to retail Naples specialties at a reasonable price to provide competition for Xeon E5-2600 Intel products. However, AMD based systems will feature more advanced specs and higher productivity.


Naples CPUs by AMD are expected to be officially introduced in the second quarter of 2017.

The release of Western Digital solid-state drives has taken place not so long ago, so now it's time to view over an advanced offer aimed primarily at enthusiasts – WD Black PCIe SSD in a 256 GB version.


Hard drives of the Black series have won fame of the fastest and most productive HDDs in the mass market of information storage systems. This imposes on the WD Black PCIe SSD a certain amount of expectations from buyers who similarly expect to get the fastest SSD for sane money.
