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. However, all PSU are classified according to different criteria, so one can find appropriate product even without 80Plus standards. The compliance with those standards is realized on 115V and 230V conditions but there are a number of standards applied to 220V-240V. Power module Chieftec A80 650W doesn’t belong to the army of 80Plus products, though can boast outstanding performance and efficiency. It is primarily targeted at the segment of affordable PSU solutions.

Design and Framework

Chieftec A80 650W design is developed in a classical template common for the models with a solid frontal fan. The casing consists of a ventilation perforation, decorative grid with the brand logo, sockets for module …

Rosewill Introduces PSU Line of 80 Plus Platinum Standards

Rosewill, Californian hardware manufacturer, has gladdened its potential customers with a new PSU line codenamed Fortress. The major peculiarity of this line is that all products are characterized by rather high efficiency coefficient: up to 94% in 230 V alternating current networks. The new line involves models of 450W, 550W, 650W, and 750W showings which have already received 80 Plus Platinum certificate.

Low power dissipation is achieved exactly due to the high efficiency which reduces ventilation demands immensely. The employment of 135 mm fans provided for the perceptible decreased of noise. Those features are considered to be the basic attraction for the customers.

All four models in Fortress line are developed according to a similar scheme with a single 12 V bus. The chief differentiation between the models lies in the output capacity and a cable set. Hence, the high-order PSU is capable to give current of up to 62.5 A; in the aggregate with the available 4 …

Meet New Series of 120-/140-mm SilentWings 3 Fans from Be Quiet!

Be Quiet! announces the upcoming release of a new series of fans, entitled SilentWings 3. The lineup will consist of 4x 120-mm & 4x 140-mm items. All greenhorns are based on fluid dynamic bearing, estimated for 300.000 hours of foolproof operation. The fans employ either 3-pin or 4-pin power connectors and might run at 12V voltage index.

Be Quiet! SilentWings 3 items have a dual purpose: they can be used as system fans and as a part of CPU cooling. The 3-pin models come equipped with an adapter for the reduction of voltage from 12V to 7-5V; due to this, their noise level dwindles down to the minimal level. In contrast, the 4-pin solutions support PWM technology.

All models are fitted with a 3-phase 6-polar motor which ensures low power consumption & inconsiderable vibrations. A unique shape of blades allows for the enhancing of airflow volume; at the same time, the incorporation of a slash frame promotes for the increase of the static pressure. Moreover, new mounts help in …
