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 …

Palit to Release GTX 1070 JetStream & GameRock Videocards

Following the official release of Nvidia’s GeForce GTX 1070 graphics adapter, the company’s partners have started unveiling their own modifications. Hence, Palit is about to launch four videocards, based on Pascal microarchitecture: GTX 1070 JetStream, GTX 1070 Super JetStream, GTX 1070 GameRock & GTX 1070 GameRock Premium Edition. All greenhorns employ GP104-200 GPU (16 nm, FinFet) with 1920 CUDA, 64 ROPs and 120 TMUs.

These videocards feature an 8-phase VRM system that uses a reliable hardware base, including solid-state capacitors and DrMOS chips. The GPU is accompanied by 8 GB of GDDR5 memory; its clock frequency across the line makes up 2.0/8.0 GHz (256 Gb/sec bandwidth) but for the GameRock Premium Edition model that delivers 2125/8500 MHz frequency & 272 Gb/sec bandwidth.

Cooling of all key components is provided by 2.5-slot coolers. They entail a copper base, a few copper heatpipes, a dual-section aluminum heatsink as well as a pair of 100 mm fans with …

Haswell processors for laptops will consume up to 57 W, desktop - up to 100

Intel provides with three graphics levels: GT1, GT2 and GT3. Desktop processors won’t receive graphics performance higher than GT2, but mobile processors will be able to boast of with GT3 class. Support of PCI Express 3.0 for Haswell processors will be quite usual characteristics, but at the memory controller little progress is seen — yet provides dual-channel DDR3-1600.

By energy consumption Haswell desktop versions will be divided into models with values of 35, 45, 65 and 95 watts of TDP level. For mobile processors the values are ​​37, 47 and 57 W. Finally, ultra book processors with built-in system logic will be filled by TDP level not more than 15 watts. It is assumed that this will enable them, among other things, be in standby mode up to 10 days without charge.

The desire of Intel to compete with AMD in terms of performance integrated in graphics processor, will add some work to companies producing cooling systems for laptops. The developers report about …
