STANDARDS AND FEATURES

The connectors and power specifications of the EA-450 Platinum PSU are all compatible with ATX12V v2.32 and
EPS12V v2.92 specifications. The EA-450 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-450 Platinum.

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-450 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.
