Compliant with ATX version 3.1 and carrying an 80 PLUS Bronze certification, this unit achieves up to 88% efficiency, helping to reduce energy waste and keep operating costs in check. With a combined +12V output of 540W and a max output current of 45A on the +12V rail, it is well suited for a wide range of mainstream desktop systems. The unit operates on an input voltage range of 200 to 240V and supports input frequencies of 50 or 60 Hz. It has a compact form factor measuring 150 x 86 x 140 mm and weighs 1450 grams.
Active Cooling and Power Protection
The MWE Bronze 550 V3 features active cooling through a single 120mm HDB fan, which provides a good balance between airflow and noise levels. Active Power Factor Correction helps maintain a stable power factor, contributing to consistent performance. The unit also incorporates multiple protection mechanisms including over power, over voltage, under voltage, and short circuit protection, all working together to help safeguard connected components.
Connectivity and Cable Management
Using a non-modular cabling design, this power supply comes with a fixed set of connectors including a 24-pin ATX motherboard connector, two 6+2 pin PCIe connectors, six SATA power connectors, and three Molex connectors. This setup provides ample connectivity for standard PC configurations without the need for additional cable management solutions.
