Power supply form factor SFX (100 × 125 × 63.5 mm) in recent years ceased to be associated with low-power devices for the office PC, and have increased watts and are quite ready to give battle to the larger power supplies in the ATX form factor (140 × 150 × 86 mm). The popularization of compact power supply contributes to a tendency to reduce processor power consumption, graphics cards and drives. However, the choice of the SFX-models are usually small, and they are much more expensive counterparts.
Focusing primarily on enthusiasts, Taiwanese Enermax has released two PSU new series of of Revolution SFX -. ERV550SWT (550 W) and ERV650SWT (650W) devices attract the attention of a modular structure (all cables, if necessary, disconnected), the support of a semi-mode fan and high efficiency (up to 92%), which is confirmed by a certificate 80 PLUS Gold organization Ecos Consulting. Corps of new products are made in black and silver colors.
The The following components are used consisting of power supply: active power factor correction mechanism (active PFC), the converter DC-DC, high temperature capacitors made in Japan, as well as protection, preventing damage to the PSU due to a short circuit, overheating, sharp increase in load, high and low input voltage , overcurrent (+3.3 V, +5 V) and excess capacity. On line 12 in both of the PSU load kept close to their face value: Revolution SFX 550W – 45,8 A / 549.6 W, Revolution SFX 650W – 54 A / 648 watts. The total load on the power supply channels + 3.3V and + 5V should not exceed 90 watts.
For active cooling of the power source node responds fan size of 80 × 80 × 15 mm, based on hydrodynamic bearings . It only starts with an increase in power consumption of the system up to 30% of the nominal power supply.
To models Enermax Revolution SFX attached flat cable black. Configuration of cables and connectors have ERV550SWT and ERV650SWT devices identical 24-pin ATX, (4 + 4) pin EPS12V, two (6 + 2)-pin PCI-E Power, six SATA Power and four 4-pin Molex
The delivery of new power units includes a fixing frame for buildings with seats for standard ATX devices. according to the resource Hermitage Akihabara Japan model Revolution SFX nominal value of 550 and 650 W will debut on December 9 at a price ¥ 14,800 (8.3 thousand. rub.) and ¥ 16,800 (9.4 thousand. rubles .), respectively. Buyers from other countries also likely to have the opportunity to purchase new items before the New year.
