Rosewill Introduces PSU Line of 80 Plus Platinum Standards

Rosewill, Californian hardware manufacturer, has gladdened its potential customers with a new PSU line codenamed Fortress. The major peculiarity of this line is that all products are characterized by rather high efficiency coefficient: up to 94% in 230 V alternating current networks. The new line involves models of 450W, 550W, 650W, and 750W showings which have already received 80 Plus Platinum certificate.



Low power dissipation is achieved exactly due to the high efficiency which reduces ventilation demands immensely. The employment of 135 mm fans provided for the perceptible decreased of noise. Those features are considered to be the basic attraction for the customers.


All four models in Fortress line are developed according to a similar scheme with a single 12 V bus. The chief differentiation between the models lies in the output capacity and a cable set. Hence, the high-order PSU is capable to give current of up to 62.5 A; in the aggregate with the available 4 …

The New Microchip PIC16F15386 Microcontroller Line Includes 13 Models

The Microchip Technology Co. has presented a new family of eight-bit PIC microcontrollers with core-independent peripherals. Among common features of these models one can highlight the presence of the internal frequency generator (32 MHz) and the memory boot partition security mechanism meant for protection from the faulty rerecording. Moreover, there is a secure device information area (DIA) storing the device unique identifier and calibration constants. The just-launched controllers are supported by the Microchip MPLAB Xpress with MPLAB Code Configurator (MCC) framework.



This line of products offers 13 samples possessing 2 Kbyte of RAM and up to 28 Kbyte of onboard flash. The specialties are incorporated into PDIP, SOIC, DFN, UDFN, UQFN and SSOP cases with an 8–48 pin count. The number of ADC and I/O channels has increased.


Presentation samples as well as stock-produced items are already available. Wholesale prices start with $0.33 per unit.

Greeting a Pair of Liquid Freezer 120 & 240 Coolers

Arctic announces a pair of liquid cooling systems entitled Liquid Freezer 120 and Liquid Freezer 240. They are targeting the most demanding CPUs designed by Intel & AMD. The first model perfectly matches processors with up to 250 W TDP, while the second one might cope with 300 W TDP. Pricing is set at 100 EUR and 130 EUR correspondingly. Both new-comers are shipped with a brand Arctic MX-4 thermal compound.



Arctic Liquid Freezer 120 accommodates a waterblock with a copper base, an efficient pump, 120-mm heatsink, long connecting hoses (326 mm), and a couple of 120-mm fans, based on a fluid dynamic bearing. They are monitored by means of PWM technology, enabling them to rates within 500-1350 RPM speed range. At the same time, the maximal noise level does not exceed 0.3 Sone.


To continue, Arctic Liquid Freezer 240 is distinguished by the implementation of a 240-mm heatsink and four 120-mm fans. Tests prove, that this cooler is able to maintain the temperature of Intel Core …
