FSP Hexa 85+ Pro 550W 80+ Bronze ATX 2.0 Non Modular Power Supply ( 550W )

The FSP Hexa 85+ Pro 550W (model HA2-550) is a non-modular ATX power supply designed for mainstream desktop builds that require stable, efficient power delivery without unnecessary complexity. Carrying the 80 PLUS Bronze certification, it delivers efficiency of 85% or greater at typical load, helping reduce energy waste and heat inside your chassis compared to uncertified units. At the heart of its design is a single +12V rail layout, which consolidates all high-current output onto one rail. This approach benefits graphics cards and other power-hungry components by eliminating the per-rail current limits found in multi-rail designs. Complementing this is a DC-to-DC module for the +5V and +3.3V rails, which improves output regulation and lowers ripple noise — a meaningful advantage for sensitive system components over extended periods of use. Power factor correction is handled actively, with a PFC value of 0.9 or greater, making the unit compliant with Energy Related ErP/EuP 2013 requirements. It accepts universal input voltage from 100 V to 240 V at 50–60 Hz, making it suitable across different regional power standards. Hold-up time exceeds 17 ms at 80% load, providing a brief buffer during power fluctuations to prevent unexpected shutdowns. The FSP Hexa 85+ Pro 550W includes Japanese electrolytic capacitors, which are associated with improved long-term reliability compared to generic capacitors. Cooling is handled by a 120 mm sleeve-bearing fan operating quietly under normal thermal conditions. All cables are flat black ribbon-style, which aids cable routing in compact cases. Protection circuits include Over Current Protection (OCP), Over Voltage Protection (OVP), Over Power Protection (OPP), and Short Circuit Protection (SCP), covering the most common failure scenarios in PC power delivery. The unit also features dual CPU power connectors to support high-end motherboards.
