STANDARDS AND FEATURES
The connectors and power specifications of the EA-550 Platinum PSU are all compatible with ATX12V v2.32 and EPS12V v2.92 specifications. The EA-550 Platinum features Universal Input, which automatically senses when you connect the power supply to any AC power source between 100 - 240V without setting a voltage switch. This power supply also features Active Power Factor Correction (PFC), which improves the power factor value of the power supply by altering the input current wave shape, helping to power transmission across the grid.
SYSTEM PROTECTION
A variety of industrial-grade safety circuitry will help protect your computer: Over Current Protection (OCP), Over Voltage Protection (OVP), Under Voltage Protection (UVP), Short Circuit Protection (SCP), Over Power Protection (OPP), Surge & Inrush Protection (SIP) and Brown-Out Protection (BOP). Sometimes the PSU will “latch” into a protected state. You will need to power off the PSU and clear the fault before it will function again. There are no user-replaceable fuses in your EA-550 Platinum.
80 PLUS® CERTIFICATION
80 PLUS® certification is the most widely recognized independent standard in power supply efficiency. An 80 PLUS® certified power supply uses less energy and generates less heat to stay cooler, run quieter and last longer. The EA-550 Platinum has been 80 PLUS® PLATINUM certified to be at least 89% efficient at a wide range of operating loads; this will lower your operating costs and help protect the environment.
