Without question, computers are more than essential technology – they have become integral to our lives. Computers do more than make living easier; they often define the functionality and design of our offices, our homes, ourselves.
The products we choose represent how we want to describe the world around us, and how we want others to describe us. Many of us are drawn to designs from Scandinavia, which are organized, clean and functional while remaining stylish, sleek and elegant. We like these designs because they harmonize with their surroundings and become nearly transparent. Brands like Georg Jensen, Bang Olufsen, Skagen Watches and Ikea are just a few that represent this Scandinavian style and efficiency.
In the world of computers components there is only one name you should know, Fractal Design.

DC Connectors

ATX 24-pin [20+4]
Provides power to the motherboard – can be split into 20-pin and 4-pin connectors, for compatibility with older ATX motherboards.
WARNING: Do not use the 4-pin connector of this cable as a ATX 12V 4-pin connector – they are incompatible.

ATX12V / EPS12V 8-pin [4+4]
Provides power to modern CPUs – can be split into two 4-pin connectors, for compatibility with older motherboards and systems with limited power consumption.
NOTE: Some motherboards, typically dual processor systems, may require a secondary 12V connector – refer to the motherboard manual for details and connector locations.

Safety Information
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 incompatible.
- 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
- Disconnect the power cord from the computer and power outlet
- Open the computer case and disconnect the power cables from all devices
- Remove the existing PSU from the case
- 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.
- Mount the PSU in the computer case – refer to the case manual for further instructions.
- Connect the ATX 24-pin cable to the motherboard.
- Connect the ATX12V cable(s) to the CPU.
- Connect the appropriate power cables to all other devices, such as graphics cards, hard drives, optical drives.
- Connect all used modular power cables to the PSU, black 6-pin connectors to black 6-pin connectors 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.
-
Close the computer case.
-
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 Edison M Series PSU.
The PSU is now in standby mode waiting for the motherboard to turn it on.
Troubleshooting
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:
- Ensure that the ATX12V cable or cables are connected correctly – consult the motherboard manual for more details.
- 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. - 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. - 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:
- 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.
- Ensure that the switch on the back of the PSU is in the ON position (marked "I").
- Disconnect and reconnect the ATX power cables attached to the motherboard.
- If possible, connect the PSU to a different motherboard, to confirm whether the PSU or the motherboard 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.
Mechanical noise / Fan noise
All fans generally get louder with time and wear. This is not a cause for a typical warranty claim. If the fan is excessively noisy on a brand new power supply, please contact the reseller.
NOTE: Over time dust can accumulate on the fan grille, and produce excessive noise - clear the accumulation using a can of compressed air.
Electrical noise / humming / coil whine
Typically, electrical noise is caused by minor incompatibility issues between components, such as between the power supply and the VRM modules on a graphics card. This noise may only occur at certain load combinations, and can therefore often be avoided by making slight changes to the power load.
Please try altering the following settings before returning your power supply to your reseller:
- Power saving features of the CPU and motherboard, such as C1E (Enhanced Halt State) and EIST (Enhanced Intel SpeedStep® Technology) – refer to the motherboard manual for more details on which features the motherboard supports and how to change their settings
- Graphics card driver options, including the "vsync" option – refer to the graphics card manual for instructions on how to changes these settings.
If the noise level is not reduced after adjusting power load settings, Fractal Design considers loud electrical noise an acceptable cause for a warranty claim.
Limited Warranty and Limitation of Liability
Fractal Design Edison M Series PSUs are guaranteed for sixty (60) months from the date of delivery to end-user, against defects in materials and/or workmanship. Within this limited warranty period, products will either be repaired or replaced at Fractal Design discretion. Warranty claims must be returned to the agent who sold the product, shipping prepaid.
The warranty does not cover:
- Products which have been used for rental purposes, misused, handled carelessly or applied such away that is not in accordance with its stated intended use.
- Products damaged from an Act of Nature including, but not limited to, lightning, fire, flood and earthquake.
• Products whose serial number and/or the warranty sticker have been tampered with or removed.
