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 additional power cables which accommodate sockets of 6+2 type, the PSU can be employed to work with high-end gaming PCs with a couple of implemented high-performance 3D cards.
450W model is equipped with a single ATX (20+4)-pin slot, a single EPS12V socket, a couple of PCI-E Power (6+2)-pin sockets, six SATA Power slots, one power cable for Floppy drive, and five 4-contact Molex sockets.
