Note

(NOT applicable to models designed for the European Union): Before you install 

your new power supply, check the red power supply voltage switch setting. It should match 

your local power voltage (115V for North America, Japan, etc., 230V for Europe, South 

East Asia, and many other countries). Change the voltage setting if necessary. If you use 

the wrong voltage setting, you could damage your system and void your warranty.

6. Connect the 24-pin Main Power Connector and the 

4-pin +12V or 8-pin +12V connector to your 

motherboard as needed. If your motherboard uses a

20-pin connector, detach the 4-pin attachment on 

the 24-pin power connector (see pictures 1 and 2).

Connect the peripheral power connectors to devices

such as hard drives, optical drives, etc.

7. Connect the Serial ATA connectors if you are using

Serial ATA hard drives.

8. Connect the PCI Express power connector to your PCI Express graphic card as needed.

9. You can connect up to three fans to the dedicated "Fan Only" connectors.

Note:

Do not 

connect devices other than fans to these connectors. If you prefer not to let the 

TP2-550EPS12V control your case fans, you can connect your case fans to the regular 4-pin

peripheral connectors.

10. Optional: If you'd like to monitor the speed if the power supply fan, connect the 3-pin fan 

signal connector to one of the fan connectors on your motherboard.

Note:

You don't need

to connect the fan signal connector in order for the power supply to work.
