Get more power and lower your electric bill with the new EarthWatts Green series! One of the most environmentally-friendlypower supplies available, the EarthWattsEA-750Green efficiently delivers 750 Watts of reliable Continuous Power while meeting the Bronze level of efficiency from 80 PLUS®, the most widely recognized independent standard in power supply efficiency. On top of that, this EarthWatts power supply offers Universal Input to automatically work on any power grid on the planet, and a 135 mm double ball bearing fan to keep cool.
The EA-750Green 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. TheEA-750Green 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.
A variety of industrial-gradesafety circuitry will help protect your computer: OCP (Over Current Protection), OVP (Over Voltage Protection), SCP (Short Circuit Protection), OPP (Over Power Protection) OTP (Over Temperature Protection) and SIP (Surge & Inrush 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 nouser-replaceablefuses in yourEA-750Green.
80 PLUS® BRONZECERTIFICATION
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-750Green 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.

The EA-750Green PSU uses quad +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 +12V rails have been assigned to different connectors, as shown in Table 2, to prevent voltage sags in one device due to sudden demands for power by another device.
TABLE2: POWERCONNECTORS ANDRAILASSIGNMENTS
1 x 8(4+4)-pinATX12V / EPS12V
2 x 8(6+2)-pinPCI-E
2 x 8(6+2)-pinPCI-E
6 x Molex
9 x SATA
The EA-750Green PSU distributes a varying maximum number of amps on each rail. To see the output capacity and regulation for each different voltage, see Table 3.
TABLE3: OUTPUTCAPACITY ANDREGULATION
Ripple & Noise
The continuous maximum total output power shall not exceed 750W. +12V1-4 DC maximum output power shall not exceed 750W.
+3.3V and +5V DC maximum combined output power shall not exceed 150W.
1. Install the EA-750Green PSU into your case with the four screws provided.
2.Connect the 24-pinmain power connector to your motherboard. If your motherboard uses a20-pinconnector, detach the4-pinattachment on the24-pinconnector.
Note: The detachable 4-pinsection cannot be used in place of a4-pin+12V connector.
3.Connect the 8-pinor4-pinATX12V connector for the CPU to the appropriate connector on your motherboard. If your motherboard has an8-pinsocket with a cover on some of the openings, we recommend that you remove the cover and use the8-pinconnector.
Note: Please also refer to your motherboard user’s manual for any special instructions.
4.Connect the PCI-Econnector(s) to your graphics card(s), if applicable.PCI-Egraphics cards use different amounts of power. For some, a single6-pinconnector is sufficient, while more powerful cards use multiple connectors, including the advanced8-pinPCI-Econnector. The8-pinPCI-Econnectors on theEA-750Green can be used as either 6- or8-pinconnectors.
5.Connect all Molex/SATA connector(s) to your hard drives, optical drives (CD/DVD/BluRay™) and other accessories. Please note that some devices will use either the older 4-pinMolex connectors, while others will use the newer15-pinSATA connector.4-pinMolex connectors have two black wires, a yellow, and a red. The SATA connector has an additional orange power wire.
6.Connect your floppy drive (if present) using the supplied FDD connector shown in Table 2.
7.Connect an AC power cord to the power supply AC inlet. Turn the switch to the “|” position after you have connected all the devices and are ready to turn on your computer.
