Power Module Chieftec A80 650W Review

The requirements of customers towards contemporary power modules are quite tough. They should own good performance characteristics and high coefficient of efficiency level, as well as 80Plus marker. The latter speaks about quality and ability to satisfy the needs of any PC.

PowerColor Intros New Graphics Card with Fling Force Cooler

TUL Corporation, in the framework of its PowerColor brand, introduces a new graphics card with quite an original way of air cooling organization. The new-coming adapter, codenamed PowerColor Radeon HD 7850 Fling Force, employs 'two-storied' cooler of an unusual structure. Along with an aluminum heatsink, copper heat pipes, and a voluminous fan, the manufacturer implemented non-monolithic fan ribs. Their tips are fixed to the main part in a way to change their location relative to the plain of rotation.

On conditions of low rotational speed, tips of the ribs are located at approximately 80 degrees angle relative to the graphics card. On conditions of heightened speed, the ribs become more linear; this way, the impeller diameter enlarges from 92 mm to 95 mm. Such structural approach to the fan framework develops into an improved performance and air cooling effect.

The model is based on Pitcairn chip, developed on Graphics Core Next architecture under 28 nm technological …
