EA-450 PLATINUM POWER SUPPLY
Antec’s EarthWatts Platinum is one of the most efficient PSU series ever created. With an 80 PLUS® PLATINUM
rating, the highest efficiency mark for power supplies, this PSU achieves up to 93% efficiency and gives you savings
unheard of from other power supplies. By using the EA-450 Platinum, you can reduce your electricity bill up to
25%. A 3 year Antec Quality warranty, a whisper-quiet 120mm DBB fan controlled by Antec’s renowned Thermal
Manager and CircuitShield™’s industry-leading 7 levels of protection make the EA-450 Platinum one of the best
choices available. Get the power you need, save money and help protect the environment with Antec’s EA-450

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
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.

INSTALLATION:
1. Install the PSU into either the top or bottom of your case with the four screws provided. Refer to your case
manual if you are unsure where the power supply should be installed.
2. Connect the 24-pin main power connector to your motherboard.
3. Connect the 8-pin or 4+4-pin connector for the CPU. 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 the AC power cord to the power supply AC inlet. Be sure to use the heavy-duty cord supplied with
your PSU.
5. PCI-E graphics cards use different amounts of power. For some, a single 6-pin connector is sufficient, making
the hardwired connector the preferred choice. More powerful cards use multiple connectors, including the
advanced 8-pin PCI-E connector. The 8-pin PCI-E connector on the PSU can be used as either a 6- or 8-pin
connector.
6. Hard drives, optical drives (CD/DVD/BluRay™) and other accessories will use either the older 4-pin Molex
connector or the newer 15-pin SATA connector. 4-pin Molex connectors have two black, one yellow and one
red wire. The SATA connector has an additional orange power wire.
7. When you have all the connections secured, turn the switch on the PSU to the “|” position.
