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 …

MSI Unveils GeForce GTX 900 Gaming Graphics Couple

Following a long-lived trend in PC hardware market, MSI has unveiled its two new videocards of GeForce GTX 900 (Maxwell architecture) series just after Nvidia’s official release. The MSI GTX 970 Gaming 4G and the MSI GTX 980 Gaming 4G models boast both, identical and dissimilar features with their reference companions. But all in good time.

Videocards from MSI are characterized by analogous with Nvidia’s models memory subsystem. Hence, it has 4 GB of GDDR5 memory modules with 256-bit interface, 224 Gb/sec bandwidth, and 7010 MHz efficient clock frequency. Quite the contrary, both GPUs differ from the etalons, chiefly due to the integration of Gaming App brand utility; the latter enables GPUs to run in one of three available modes: Silent, Gaming and OC.

The MSI GTX 970 Gaming 4G operates at 1051 MHz/1114 MHz/1140 MHZ at the start (showings for three modes) but might be overclocked to 1178 MHz/1253 MHz/1279 MHz respectively. The MSI GTX 980 Gaming 4G runs at 1140 …

ASRock Surfaces J3355B-ITX Mainboard

ASRock enters the market with a mainboard, targeting new Intel Apollo Lake CPUs (14 nm, Intel Goldmont micro-architecture). The J3355B-ITX model is thought to be integrated within laptops or entry-level all-in-one solutions. As seen from the codename, the board is developed in mini-ITX form-factor. It comes equipped with Intel Celeron J3355 processor, operating at 2.0-2.5 GHz frequency. The CPU features 10 W TDP; hence, cooling is backed by a noiseless passive cooler.

ASRock J3355B-ITX accommodates a pair of SO-DIMM slots for DDR3/DDRL3 modules with 1866 MHz frequency (up to 16 GB). The board comes with an integrated Intel HD Graphics 500 GPU that runs at 700 MHz. The connection of drives is realized via two SATA III ports. The incorporated PCIe 2.0 x16 slot is optimal for expansion cards, rather than a VGA card.

To continue, audio subsystem is based on 7.1-channel Realtek ALC887 controller, whereas network facilities are ensured with the help of Realtek RTL8111GR …
