Powerful EVGA power supply with fully modular cable management

The models of the B3 series are available in several power stages, all of which meet the requirements of 80Plus bronze and thus achieve at least 85% efficiency at medium load. Compared to older bronze power supplies, EVGA offers above all a further improved voltage regulation, a completely modular cable management and the intelligent ECO thermal control system, whereby the high-quality LongLife Sleeve Bearing fan in the 130 mm format can work extremely quietly.

Thanks to DC-DC down-conversion, +3.3 and +5 volts are independently controlled, which in particular improves the suitability for asymmetrical loads, which are almost permanent in modern systems. Thus EVGA B3 power supplies are also officially suitable for the modern Intel platforms according to Haswell. At the same time, this results in the full availability of the rated power as a + 12 volt voltage, if the situation so requires. For example, the graphics card and processor can access up to 448.8 watts with the 450 Watt model offered here. This means that the total nominal power can also be used by real systems.

EVGA also relies on quality: On the main board, exclusively electrolytic capacitors of Japanese brands are used, whose quality control is considered particularly strict. A 130 mm fan with LongLife Sleeve Bearing provides the necessary airflow under the air inlet in the low-resistance grill design. Thanks to ECO Thermal Control System, it is also possible to operate extremely quietly at low and medium loads, which also increases the longevity of the fan. Matching EVGA on all B3 gives a 5 year warranty.

EVGA is based on a completely modular cable management system: the mainboard and CPU are supplied via a 24-pin and 4 + 4-pin connector. A cable harness with two 6 + 2-pin connectors provides enough capacity for a high-performance graphics card. In addition, a total of six SATA, three 4-pole Molex and a Molex-to-Floppy adapter plug are available. In short, the EVGA B3 is the ideal power supply for high-performance gaming PCs!
