Features

STABLE POWER
The GQ series has outstanding electrical performance with ultra stable voltage and extremely clean power output. This can help you achieve the highest possible overclock (optional) and provide the most stable and reliable power to all components. The GQ series also has high efficiency up to 90% (115VAC) / 92% (220VAC~240VAC) efficiency and is 80 PLUS® GOLD certified.
ECO THERMAL CONTROL SYSTEM
The EVGA ECO Intelligent Thermal Control System provides silent operation at low loads, improved efficiency and longer life span of the fan. Enabled by a simple switch directly on the power supply, the “No Fan Spin” feature is ideal for users looking to reduce ambient noise overall. Save on energy costs and unnecessary fan usage with the EVGA ECO Thermal Control System.
TOP QUALITY PROTECTIONS
The GOLD series comes equipped with the most comprehensive protection set possible, including Over Voltage Protection (OVP), Under Voltage Protection (UVP), Over Power Protection (OPP), Short Circuit Protection (SCP), Over Current Protection (OCP), and Over Temperature Protection (OTP). This product is also covered by an exceptional 5-year warranty and EVGA’s legendary customer service and support.
SUPERIOR BUILD QUALITY
The GQ series is built to the highest standards, using 100% Japanese capacitors rated at 105 degrees Celsius and high quality brand-name semiconductor components for the highest performance and reliability. The Ultra Quiet 135mm Fluid Dynamic Bearing fan provides adequate cooling to allow near silent operation.
MODULAR DESIGN
Reduce clutter in the case, improve ambient temperatures with better airflow overall and provide a clean look to any system. Modular PSU designs allow the user to disconnect the cables from the power supply side if they are not needed for the specific configuration. This can help free up space inside the case and improve cable management as well as airflow throughout the system.

Installation

Remove the power supply from its packaging.
(Optional) Using the provided PSU testing tool, connect the 24-Pin cable to the PSU, then attach the testing tool to the 24-Pin cable. Connect the ATX power cable to the PSU and plug the PWR cable into the outlet or surge protector/UPS you plan to use. Once connected, turn the power switch to the ON position. (If the ECO mode is set to ON, the fan will not spin)
Please note: If you are using a water cooling configuration, this testing tool provides a simple, safe, option for bleeding/draining/testing water cooling components without the need of a paperclip or other device.
Use the screws provided with your case to install the power supply into your computer. NOTE: It is recommended to install the power supply with the fan facing down. However, if your case places the power supply at the bottom of the case and there are no ventilation holes available, it may be best to install the power supply with the fan facing up for greater efficiency and reliability.
Connect the 24-Pin ATX cable to the PSU and the motherboard.
Connect the 4+4-Pin EPS12V cable to the motherboard. (Optional) – If you plan on extreme overclocking and your motherboard supports additional 8-Pin or 4-Pin CPU power connectors, connect the second 4+4-Pin EPS12V cable. This is only needed for heavy overclocking or for Dual CPU motherboards.
Connect the 6/6+2-Pin PCI-E cables to your graphics card(s).
NOTE: Do not attempt to plug an 8-Pin PCI-E cable into a 6-Pin connector without first detaching the two extra pins.
Connect SATA power cables to all data drives or optical drives (hard drives, solid state drives, optical drives).
Connect the peripheral “Molex” 4-Pin connectors for fans, pumps, legacy components and other devices/adapters.
Connect the AC power cord to your power supply and to the wall. Check all connections to assure a solid connection and turn the power switch on the power supply to the ON position.

TROUBLESHOOTING

I see there are more than four screw holes on the back of the power supply, but the packaging only offers (4) screws, are some missing?

Nothing is missing; you will only need to attach the EVGA power supply to the case with four screws. The power supply offers more than (4) holes to provide optimal compatibility for today’s varied case designs.

My EVGA Power Supply includes (2) EPS cables for my motherboard, do I need to connect up both?

Motherboards only require (1) 4+4 or 8-Pin EPS connection. On some models, an additional 4+4-Pin or 8-Pin connection on the motherboard may be found for dual CPU configurations or for extreme overclocking. If your motherboard supports dual 4+4-Pin EPS connections, please refer to your motherboard manufacturer’s manual for details on the proper function and power of the EPS connections.

What is the ECO Thermal Control System?

The ECO Thermal Control System, when enabled, allows the fan on your EVGA power supply to shut off during low to moderate operation loads. The EVGA power supply’s fan will automatically turn back on when needed, based on the temperature the power supply reaches. The fan will also increase in RPM when needed, based on the load operation being requested from the components connected. This prevents unnecessary rotation, reduces ambient noise levels and will increase the life span of the fan due to the fan not spinning when not required.
Please Note: If the ECO Thermal Control is disabled the fan will always spin, even at low loads. The fan will also increase in RPM as needed automatically, based on the power draw from connected components.

What if I want to use power adapters for my graphics card(s)/motherboard/peripherals?

EVGA always recommends the use of direct power connections from the power supply to power all components.

Does it matter which end of the cable I plug into the power supply?

Yes, the connections going to the power supply will not have “break downs” like the EPS (CPU) has 4+4 on one side and full 8-Pin on the other. Check each cable as it is labeled appropriately to match the power supply side, and connect only the same ‘‘matching” cable directly to the power supply as referenced on each connector.

If I have an issue or a question, can I get support?
