Computer does not start
Open the computer case and check if the standby LED on the motherboard is lit.
Note:
The LED can be in various shapes and in different positions on the motherboard – refer to the
motherboard manual for more details.
Motherboard LED is ON
In this case, the PSU is supplying the motherboard with standby power. Several common issues can
cause it not to turn on, please check the following before returning the PSU to the reseller:
1. Ensure that the ATX12V cable or cables are connected correctly – consult the motherboard manual
for more details.
2. Ensure that the case’s power button cable is correctly connected to the motherboard – consult the
motherboard manual for more details.
As an alternative, connect the two “Power Button” pins on the motherboard to the reset button
cable from the case, then push the reset button. This will confirm whether or not the case’s power
button is working correctly.
3. Disconnect all non-essential devices. Leave the PSU, system memory (RAM), CPU and CPU-
cooler connected to the motherboard,.
If the computer starts in this configuration, reconnect the other components one by one to identify
the faulty device.
4.
If possible, connect the PSU to a different set of essential devices to confirm it is faulty.
Motherboard LED is OFF
In this case, the motherboard could be faulty, or not supplied with standby power from the PSU. Please
check the following before assuming that the PSU is faulty and returning it to the reseller:
1. Ensure that the main power cord is connected to both the PSU and to a live power source. Check
the power outlet with another electric device, such as a lamp, to ensure that it provides power.
2. Ensure that the switch on the back of the PSU is in the ON position (marked “I”).
3. Disconnect and reconnect the ATX power cables attached to the motherboard.
4.
If possible, connect the PSU to a different motherboard, to confirm whether the PSU or the mother
-
board is faulty.
Computer powers on but then immediately turns off
Refer to the same troubleshooting steps as for the “Motherboard LED is ON” section above.
Power supply is noisy
All Fractal Design power supplies have been developed with low noise levels as a high priority. However,
PSUs are typically never completely silent. PSU noise should be barely perceptible with the computer
case closed.
Troubleshooting

Safety Information
English
The following information is provided for personal safety and the correct operation of the PSU:
•
Never open the PSU case – the power unit can discharge hazardous voltages. Additionally, there
are no user-serviceable components inside.
•
Only operate the PSU in safe and dry environments.
•
Never insert objects into the fan grille, or the open ventilation areas, of the PSU.
•
Do not modify PSU cables and/or connectors.
•
Do not use the 4-pin connector of the ATX 24-pin cable as a ATX12V 4-pin cable – they are incom-
patible.
•
The ATX12V and the PCI-E connectors are incompatible and cannot be interchanged – do not
force the connectors.
Installation
If replacing an existing power supply, continue with Section A; if not, skip to Section B.
Part A: Removing the existing PSU
1. Disconnect the power cord from the computer and power outlet
2. Open the computer case and disconnect the power cables from all devices
3. Remove the existing PSU from the case
4. Continue with Section B
Part B: Installing the new Fractal Design PSU
Do not connect the AC power cord to the new PSU before completing steps 1 through 5.
1. Mount the PSU in the computer case – refer to the case manual for further instructions.
2. Connect the ATX 24-pin cable to the motherboard.
3. Connect the ATX12V cable(s) to the CPU.
4. Connect the appropriate power cables to all other devices, such as graphics cards, hard drives,
optical drives.
5. Connect all used modular power cables to the PSU, black 6-pin connectors to black 6-pin connec-
tors and grey 8-pin to grey 8-pin connectors.
Note:
The 6-pin and 8-pin modular connectors are incompatible with one another; however, it is
irrelevant to which PSU receptor they are connected.
6. Close the computer case.
7. Connect the AC power cord and switch the button on the back of the PSU to the ON position.
Congratulations! You have successfully installed your new Integra M Series PSU.
The PSU is now in standby mode waiting for the motherboard to turn it on.
