ATX12V version 2.2 power supply

Model EA-650

The EarthWatts EA-650 is an advanced power supply with three 12-volt rails for powering quad core processors and high-end video cards. The EA-650 power supply is built to be compatible with the ATX12V version 2.2 specification. EarthWatts’ circuitry delivers safer and more reliable output to your system’s components and its higher energy efficiency reduces power consumption by up to 25%, saving you money on your electricity bill.

EarthWatts power supplies have achieved 80 PLUS® Certification, the latest independent standard in power supply efficiency. In addition, EarthWatts feature a variety of circuitry protection: OCP (over current protection), OVP (over voltage protection), and SCP (short circuit protection).

EarthWatts also include Universal Input with Active Power Factor Correction (PFC). Universal Input allows you to connect your EarthWatts power supply to any AC power outlet between 100~240V without having to worry about setting a voltage switch. Active PFC reduces electrical waste by improving the power factor value to the power supply, helping the power plant to provide power more efficiently.

Power Switch

The PSU has a main power switch. Make sure you turn the switch to the ON (I) position before you boot up the computer for the first time. Normally, you won’t need to switch to the OFF (O) position, since the PSU includes a soft on/off feature. This lets you turn the computer on and off by using the soft switch on the computer case. If the computer crashes and you can’t shut it down using the soft switch, you can switch the main power to the OFF (O) position to shut the system down, then turn the switch back to the ON (I) position and restart.

Installation

1.Turn off the hard power switch, if any, on your old power supply.

2.Disconnect the power cord from your old power supply.

3.Open your computer case according to the directions provided in your case manual.

4.Disconnect all power connectors from the motherboard and from the peripherals devices such as case fans, hard drives, optical drives, floppy drives, etc.
