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 …

LEPA to Release MX-F1 and MaxGold 1000 PSUs

LEPA is ready to release a new series of entry-level power supply units entitled MX-F1. The series counts three models of 400 W, 500 W and 600 W capacity: N400-SA-EU, N500-SA-EU and N600-SA. In addition, the company has expanded its MaxGold line with a flagship 1000-watt model. It corresponds to Intel ATX12V 2.4 standard and employs an optimized hardware design.



To begin with, MX-F1 PSUs offer 87% of ultimate efficiency. Operating at 20%/50%/100% loading, they are able to achieve 82%/85%/82% efficiency correspondingly. Nonetheless, the models cannot receive 80Plus Bronze certificate, since they feature limited voltage input range. All the models within the series employ a single +12V rail and boast a non-modular design.


This promotes for the connection of middle-efficiency components. They support Active PFC and a wide spectrum of protective functions (over-voltage, over-current, over-power, short-circuit). Cooling of internal components is ensured by a single 120 mm fan. …

Zalman Divulges Basic Specifications of PSU GoldRock XG Series

Zalman, a recognized manufacturer of cooling systems, PC enclosures and other hardware units, is going to replenish its lineup of products with a high-end PSU series. Codenamed GoldRock XG, the series will be represented by three models of 550W, 650W and 750W power efficiency, ZM550-XG, ZM650-XG, and ZM750-XG correspondingly. The preliminary data demonstrates that all models are equipped with high-level components which allow the product to gain 80 Plus Gold certificate standard. Moreover, Zalman claims that its new PSUs will comply with EPS12V v2.92 and ATX12V v2.3 standards.



GoldRock XG power supply units will be distinguished by high efficiency index that will fluctuate within the measures of 88% to 92%. All the models will be released with the implementation of heat-resistant capacitors with solid and liquid insulator. The series will also boast the integration of LLC topology and DC-DC converter. The latter will ensure the utmost reliability and profitability of the …
