EA-380D GREEN POWER SUPPLY
THE ENERGY-EFFICIENT PSU
Get the power you need and the low electric bill you want with Antec’s EA-380D Green! One of the most
environmentally friendly power supplies on the planet, the EA-380D Green delivers 380 watts of reliable,
continuous power while meeting the Bronze level of performance from 80® PLUS, the most widely
recognized independent standard in power supply efficiency.
STANDARDS AND FEATURES
The EA-380D Green PSU is compatible with ATX12V v2.3 and EPS12V v2.91 specifications. This PSU
features Universal Input, which automatically senses when you connect the power supply to any AC
power source between 100 ~ 240V, eliminating the need to set a voltage switch. The EA-380D Green
also features Active Power Factor Correction (Active PFC), which improves the power factor value of the
PSU by altering the input current wave shape, helping to transmit energy across the grid.
SYSTEM PROTECTION
A variety of industrial-grade safety circuitry will help protect your computer: OVP (Over Voltage
Protection), SCP (Short Circuit Protection), and OCP (Over Current Protection). Sometimes the PSU will
“latch” into a protected shutdown state. This means that 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-380D Green.

80 PLUS® BRONZE CERTIFICATION
80 PLUS® Bronze certification is among the highest independent standards in power supply efficiency.
This allows the PSU to use less energy and generate less heat so it stays cooler, runs more quietly, and
lasts longer. The EA-380D Green has been certified to be at least 82% efficient at a wide range of
operating loads and will lower your operating costs while protecting the environment.

DUAL +12 VOLT RAIL DISTRIBUTION
The EA-380D Green PSU uses dual +12 volt power rails. Different connectors are hooked up to separate
circuits to aid in the balanced distribution of power between devices in your computer. The engineers
have allocated the rails to different connectors, as shown in Table 2, to prevent voltage sags in one
device due to sudden demands for power by another device.

Note: No power cord included. By reusing your existing cord, you can reduce waste and help protect the
environment.
POWER OUTPUT
The EA-380D Green PSU distributes a varying maximum number of amps on each rail. To see the output

INSTALLATION:
1. Install the EA-380D Green PSU into your case with the four screws provided.
2. Connect the 24-pin main power connector to your motherboard. If your motherboard uses a 20-
pin connector, detach the 4-pin attachment on the 24-pin connector.
Note: The detachable 4-pin section cannot be used in place of a 4-pin +12V connector.
3. Connect the 8-pin or 4-pin ATX12V connector for the CPU to the appropriate connector on your
motherboard. If your motherboard has an 8-pin socket with a cover on some of the openings,
we recommend that you remove the cover and use the 8-pin connector.
Note: Please also refer to your motherboard user’s manual for any special instructions.
4. Connect an AC power cord to the power supply AC inlet. To reduce waste, the EA-380D Green
does not come with a power cord. Turn the switch to the “|” position after you have connected
all the devices and are ready to turn on your computer.
