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 …

Dell Replenishes 2013 S Series with Five New Monitors

The past few days were marked by the introduction of new monitors designed by Dell. The five models supplemented the series 2013 S and expanded the integrated facilities for the customers.

All the models feature Full HD resolution of 1920x1080, good viewing angles (178/178 degrees) and thin display frame.

Monitor S2440L is characterized by fast response time that approximates 5 ms and 5000:1 color contrast. At the same time, models based on IPS feature 7 ms array response time (during transition from gray to gray) and 1000:1 color contrast.

The difference between the models is also seen in the integration of different video ports. The monitor with 27-inch diagonal is equipped with two-port USB-hub and such video outputs as DVI, HDMI and D-Sub. Models S2440L, …

Company LEPA produces new power supplies B-series

LEPA introduced three new power supplies — B650-SA, B700-MAS and the B800-MAS, which will replace older models B750-MA, and B850-MA. Newcomers have been certified with 80 Plus Bronze (efficiency of 88% of the networks 230V), and met the standards of ATX12V v2.3 and EPS12V 2.92, and positioned as solutions for gamers and owners of GPU configurations SLI and CrossFire, workstations and small servers.

New items are equipped with inverter DC-DC (to improve stability), have the topology of Double Forward Circuit, as well as high-quality electrical components: solid capacitors and heat resistant (105 ° C) capacitors made in Japan.

Active cooling LEPA B700-MAS/B800-MAS is provided by 140-mm fan on double bearings. The model B650-SA has a fan size of 120 mm. The intensity depends on the rates of temperature sensor. Power Cables PCI-E, SATA and Molex flat are detachable. The main ATX 24-pin, as well as “CPU” EPS12V 8-pin are collected in a nylon sheath. LEPA B650-SA has …
