T HE E NERGY -E FFICIENT PSU
Get more power nd lower your electric bill with the new E rthW tts Green series! One of the
most environment lly-friendly power supplies v il ble, the E rthW tts EA-750 Green
efficiently delivers 750 W tts of reli ble Continuous Power while meeting the Bronze level of
efficiency from 80 PLUS®, the most widely recognized independent st nd rd in power supply
efficiency. On top of th t, this E rthW tts power supply offers Univers l Input to utom tic lly
work on ny power grid on the pl net, nd 135 mm double b ll be ring f n to keep cool.
S TANDARDS AND F EATURES
The EA-750 Green PSU is comp tible with ATX12V v2.3 nd EPS12V v2.91 specific tions. This PSU
fe tures Univers l Input, which utom tic lly senses when you connect the power supply to ny AC
power source between 100 ~ 240V, elimin ting the need to set volt ge switch. The EA-750 Green lso
fe tures Active Power F ctor Correction (Active PFC), which improves the power f ctor v lue of the PSU
by ltering the input current w ve sh pe, helping to tr nsmit energy cross the grid.
S YSTEM P ROTECTION
A v riety of industri l-gr de s fety circuitry will help protect your computer: OCP (Over Current
Protection), OVP (Over Volt ge Protection), SCP (Short Circuit Protection), OPP (Over Power Protection)
OTP (Over Temper ture Protection) nd SIP (Surge & Inrush Protection). Sometimes the PSU will “l tch”
into protected shutdown st te. This me ns th t you will need to power off the PSU nd cle r the f ult
before it will function g in. There re no user-repl ce ble fuses in your EA-750 Green.
80 PLUS® B RONZE C ERTIFICATION
80 PLUS® Bronze certific tion is mong the highest
independent st nd rds in power supply efficiency. This
llows the PSU to use less energy nd gener te less he t
so it st ys cooler, runs more quietly, nd l sts longer. The
EA-750 Green h s been certified to be t le st 82%
efficient t wide r nge of oper ting lo ds nd will
lower your oper ting costs while protecting the
environment.

Q UAD +12 V OLT R AIL D ISTRIBUTION
The EA-750 Green PSU uses qu d +12 volt power r ils. Different connectors re hooked up to sep r te
circuits to id in the b l nced distribution of power between devices in your computer. The +12V r ils
h ve been ssigned to different connectors, s shown in T ble 2, to prevent volt ge s gs in one device
due to sudden dem nds for power by nother device.

I NSTALLATION :
1. Inst ll the EA-750 Green PSU into your c se with the four screws provided.

2. Connect the 24-pin m in power connector to your motherbo rd. If your motherbo rd
uses 20-pin connector, det ch the 4-pin tt chment on the 24-pin connector.
Note The det ch ble 4-pin section c nnot be used in pl ce of 4-pin +12V connector.
3. Connect the 8-pin or 4-pin ATX12V connector for the CPU to the ppropri te connector
on your motherbo rd. If your motherbo rd h s n 8-pin socket with cover on some of
the openings, we recommend th t you remove the cover nd use the 8-pin connector.
Note Ple se lso refer to your motherbo rd user’s m nu l for ny speci l instructions.
4. Connect the PCI-E connector(s) to your gr phics c rd(s), if pplic ble. PCI-E gr phics
c rds use different mounts of power. For some, single 6-pin connector is sufficient,
while more powerful c rds use multiple connectors, including the dv nced 8-pin PCI-E
connector. The 8-pin PCI-E connectors on the EA-750 Green c n be used s either 6- or
8-pin connectors.
5. Connect ll Molex/SATA connector(s) to your h rd drives, optic l drives
(CD/DVD/BluR y™) nd other ccessories. Ple se note th t some devices will use either
the older 4-pin Molex connectors, while others will use the newer 15-pin SATA
connector. 4-pin Molex connectors h ve two bl ck wires, yellow, nd red. The SATA
connector h s n ddition l or nge power wire.

6. Connect your floppy drive (if present) using the supplied FDD connector shown in T ble
2.
7. Connect n AC power cord to the power supply AC inlet. Turn the switch to the “|”
position fter you h ve connected ll the devices nd re re dy to turn on your
computer.
