PSU Evga 500B: a Perfect ‘Price-Quality’ Combination

Evga, a merited designer of a large spectrum of PC components, is about to release a new power supply unit, entitled 500B (codename: 100-B1-0500-KR). As seen from the title, this model features 500W power and is oriented at saving users, rather than enthusiasts. The unit is already marked by 80Plus Bronze certificate, due to 80% efficiency level on ordinary loading. Upon the whole, 500B is thought to be a perfect ‘price-quality’ combination, ready to comply with all basic users’ requirements.

Evga 500B employs a single +12V rail that ensures a stable power supply to the connected components and guarantees compatibility with new equipment. The unit is estimated for 40A current at +12V rail. Stability of operation might be secured also by means of an onboard protection system; it saves the system from power disruptions, overloading, low input voltage, high voltage, and from short circuit.

To continue, quiet and reliable PSU operation is a merit of a low-noise fan. It …

Gigabyte Readies Entry-Level Graphics Card GV-N640D5-2GI

Gigabyte is going to introduce one more entry-level graphics solution that corresponds to the updated Nvidia GeForce GT 640 series. Entitled Gigabyte GeForce GT 640 (GV-N640D5-2GI), the card employs GK107 GPU, running at 1046 MHz frequency instead of the preceding 900 MHz. The core, developed under 28 technological process, utilizes 384 CUDA cores.

It’s necessary to underline that the new-comer differs by the availability of 2 GB memory, whereas all etalon models take 1 GB only. Memory is represented by 64-bit GDDR5 chips that run at 5010 MHz effective frequency, if compared with 1800 MHz frequency that DDR3 modules demonstrate.

GV-N640D5-2GI comes with an improved design of PCB where a brand Ultra Durable 2 concept has been incorporated. This concept implies the employment of a high-quality hardware base, involving durable solid-state capacitors, transistors with low channel resistance RDS (on), and ferrite throttles with reduced power loss. Traditionally, the model …
