SEASONIC 450W Prime Fanless Platinum Power Supply Installation Guide

SEASONIC 450W Prime Fanless Platinum Power Supply

Remove your old PSU (power supply unit)

1. Disconnect your AC power cord from the wall socket and the back of the power supply.
2. Disconnect all DC cable connectors.
3. Remove all 4 mounting screws.
4. Remove your old PSU.

Test your Seasonic PSU before installation

1. Plug the AC power cord into the PSU. Make sure that the AC power is coming directly from the wall outlet. It is recommended to use a high quality surge protector to protect the PSU and the system.
2. Connect both the 18-pin and 10-pin connectors of the motherboard cable to the power supply.
3. If you power supply features a fan control switch, set it to Normal Mode. In Hybrid or Fanless Mode (S3FC) the fan will not turn.
4. Attach the Power Supply Tester to the 24-pin motherboard connector. There is a notch on the Tester that fits directly into the notch on the 24-pin connector.
5.  Turn on the power supply by setting the 1/0 switch to the “I” (ON) position. If the power supply fan starts spinning then your PSU is working.

The drawings illustrate a fully modular PSU with a fan control switch; the features of your actual PSU might vary.

Position your PSU

Bottom of the case

• The fan control setting determines the optimal PSU placement.

In “Hybrid” mode

• Seasonic recommends to install your PSU with ventilation top cover facing UPWARD, towards the direction of the motherboard. This will ensure natural heat dissipation.

Fanless PSU

• The PSU must be mounted into the computer case with the ventilation top cover facing UPWARD.

1. Flat Desktop-, SFX- or ITX systems
2. Top of the case

In “Normal” mode

Although the direction of mounting is optional, it is not recommended to install the PSU with the ventilation top cover facing downward if there are no ventilation holes on the bottom of the case. To learn about the ventilation of your computer case, please refer to the case manufacturer’s instruction manual.

In general, it is recommended to mount the PSU with the ventilation top cover facing the motherboard. Due to the different varieties of case layouts, however, please also consult the case manufacturer’s instruction manual for more information. Seasonic recommends the PSU to be mounted with its ventilation top cover facing DOWNWARD.

Top of the case

Install your Seasonic PSU

2. Make sure the PSU switch is in the “O” (OFF) position.
3. Select the fan control type if your PSU has this option.
4. Connect all the necessary system DC cables (Motherboard, CPU, VGA, HDD, Optical Drivers, etc). The connectors should click to lock in.

ATTENTION:  Use only cables provided by Seasonic! Should you require additional cables, please contact Seasonic.

Motherboard cable

• Make sure both Motherboard connectors on the PSU side are properly connected.

Peripheral cables (6-pin connectors)

The drawings illustrate a fully modular PSU with a fan control switch; the features of your actual PSU might vary.

High-powered graphics cards are usually outfitted with two (or three) PCle power connector slots. Seasonic prefers the use of two (or three) separate PCle cables to connect these cards to your power supply.

Power Supply Installation

1. Place the Seasonic power supply into the space provided within the case and use the four mounting screws provided in the accessory bag to secure it to the back panel of the case. Do not over-tighten the screws.
   • For power supplies with a built-in fan, the fan side top cover should be facing the mainboard. (Depending on the type of computer case, this can mean either upwards or downwards facing fan cover.)
2. For fanless power supplies, Sea Sonic recommends to mount fanless power supplies into the computer case with their ventilation cover facing UPWARDS. However, there are extra mounting-screw holes provided on the back of the power supply to allow for reverse mounting, if necessary
3. Mainboard connection:
   • DO NOT force the connectors into place; the connectors are “keyed” so they can only fit one way. Make sure the connectors lock in their place securely.
   • Connect the power supply end of the 24/20-Pin convertible connector to the appropriate receptor on the power supply unit.
   • Connect the mainboard end of the 24/20-Pin convertible connector to the mainboard. Depending on the mainboard, you may need to either attach or detach the 4-Pin module of the 24/20-Pin connector.
   • Connect the + 12 V 4-Pin connector and the EPS + 12 V connectors, if applicable.
   • If your system requires dual EPS + 12 V connectors, please connect the 8-Pin end of the second CPU 8-Pin connector into the appropriate 8-Pin receptor on the power supply unit. Then connect the mainboard end of this 8-Pin connector to the mainboard.
4. Peripheral components connection:
   • Connect one end of the peripheral cable to the power supply and the other end to the component.
   • DO NOT use excessive force to attach the connectors; the connectors are “keyed” so they can only fit one way.
   • Make sure that the connectors lock in tightly and securely.
5. Close the computer case according to the manufacturer’s instructions.
6. Plug in the AC power cord provided in the box and switch the AC On/Off switch on the back panel of the power supply to the “I” (On) position.
7. You are now ready to start your computer powered by Seasonic.

Troubleshooting

If the power supply unit fails to function properly, please go through the below checklist.

2. Check to make sure the AC source is On.
3. Check to make sure the AC On/Off switch on the back panel of the power supply unit in the “I” (On) position.
4. Check and secure all mainboard and peripheral connectors.
5. The AC on/off switch on the back of the power supply unit can be toggled between “I” and “O” a few times with a 0.5-second delay in between to make sure the power supply unit is reset.
6. If you are still experiencing difficulties to get the power supply unit to function properly, please visit www.seasonic.com for further technical support instructions.

Notes

• The operation of power supply is a “pull” technology, which means that the unit only provides the power as demanded by the mainboard and the system components.
• If there is a mainboard malfunction, the power supply will not turn on.
• If there is a peripheral component malfunction, the power supply will not provide power to that particular component.
• This power supply complies with the newest ErP 2013 requirements. For proper system function please update your main-board BIOS to the newest version and configure the BIOS in accordance to ErP 2013 requirements – enable all Energy Savings functions for standby and normal operations and disable audio always-on.
