Greeting PowerColor Radeon R9 290X New-Generation Graphics Cards

PowerColor has officially introduced a pair of high-efficiency graphics cards developed on the new-generation Radeon R9 290X series adapters. Codenamed PowerColor Radeon R9 290X, both new-comers support the latest graphics technologies, i.e. DirectX 11.2 and OpenGL 4.2. The models feature a totally identical design, still there is one differentiation: one of the models is equipped with a key to Battlefield 4 game. Such ‘bonus’ has resulted in a bit heightened price of $580, if compared with the standard model that costs $550.

Both cards are based on AMD Hawaii XT chip. It has been dynamically overclocked by PowerColor to 1030 MHz, whereas the nominal clock frequency remained the same – 800 MHz. In order to enhance the performance, the GPU has been supplemented with 4 GB of GDDR5 memory with 512-bit interface that runs at 5000 MHz.

To proceed with the specifications, both graphics adapters accommodate four rear video ports (HDMI, DisplayPort, DVI-I, and DVI-D). …

MSI is preparing new model - Radeon HD 7970 with a water-block

The well-known in IT-maker Company MSI announced about appearance of new videoadapter based on GPU Tahiti XT chipset. Its diversity from the other Radeon HD 7970 can be seen with the naked eye, instead of an air cooler practically the entire surface of the PCB is covered with waterblock brand EK. It differs markedly from the original version, since it is designed specifically for the MSI R7970 Lightning model. Relation of adapter to the Lightning series is easily determined by the inscription at the interface connector PCI-E 3.0 x16, as well as non-standard set of video outputs (2x DVI, 4x Mini DisplayPort) and configuration of additional power connectors (2x PCI-E Power 8-pin).

Obviously, the accelerator is positioned as the Radeon HD 7970 GHz Edition and has a nominal frequency of at least 1050 MHz. Will MSI risk, like Sapphire did, and provide the card with 6 GB of memory? Probably not. The «advanced» composition of the printed circuit board and water block of full coverage …

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. …
