The EA-750 PSU s compat ble w th ATX12V v2.3 and EPS12V v2.91 spec f cat ons. The EA-750 features Un versal
Input, wh ch automat cally senses when you connect to any AC power source between 100~240V w thout hav ng
to worry about sett ng a voltage sw tch. Th s power supply also features Act ve Power Factor Correct on (Act ve
PFC), wh ch mproves the power factor value of the power supply by alter ng the nput current wave shape, help ng
to power transm ss on across the gr d.

ROTECTION
A var ety of ndustr al-grade safety c rcu try w ll help protect your computer: OVP (Over Voltage Protect on), SCP
(Short C rcu t Protect on), and OCP (Over Current Protect on). Somet mes the PSU w ll “latch” nto a protected
state. Th s means that you w ll need to turn off the PSU and clear the fault before t w ll funct on aga n. There are
no user-replaceable fuses n your EarthWatts PSU.

ERTIFICATION
The 80 PLUS® cert f cat on program sets the h ghest ndependent standards n power supply eff c ency. Th s means
that the PSU w ll generate less heat so t stays cooler, runs more qu etly, and lasts longer. The EarthWatts ser es
has been cert f ed to be at least 80% eff c ent at a w de range of operat ng loads and w ll lower your operat ng
costs wh le help ng to protect the env ronment.

The EA-750 uses Advanced Hybr d Cable Management. Cables that are mportant or mandatory are connected
d rectly to the PSU. There are also modular connectors on the back of the PSU to add add t onal cables as needed.
Us ng only the power cables you need reduces clutter and mproves a rflow ns de your case. For the l st of
connected and opt onal cables, see Table 1.

ISTRIBUTION
The EA-750 PSU uses four separate +12-volt power ra ls. D fferent connectors are hooked up to separate c rcu ts to
a d n the balanced d str but on of power between dev ces n your computer. The eng neers have allocated the ra ls
to d fferent connectors to prevent voltage sags n one dev ce due to sudden demands for power n another dev ce.

NSTALLATION
:
1. Install the EA-750 PSU nto your case w th the four screws prov ded.
2. Connect the 24-p n ma n power connector to your motherboard. If your motherboard uses a 20-p n
connector, detach the 4-p n attachment on the 24-p n connector.
Note: The detachable 4-p n sect on cannot be used n place of a 4-p n +12V connector.
3. Connect the 8-p n or 4-p n connector for the CPU. If your motherboard has an 8-p n socket w th a cover
on some of the open ngs, we recommend that you remove the cover and use the 8-p n connector.
Note: Please also refer to your motherboard user's manual for any spec al nstruct ons.
4. Connect the cables from the cable pack to the socket on the power supply as needed. If you are go ng to
plug the add t onal PCI-E cable nto the PSU, t should go nto the red socket. If the red socket s not be ng
used for PCI-E, then t can be used for another cable from the pack that accompan es the PSU.
5. Connect the AC power cord to the power supply AC nlet. Please be sure to use the heavy-duty cord
suppl ed w th your EA-750. Turn the sw tch to the “|” pos t on after you have connected all the dev ces,
and you are ready to turn on your computer.
