X7 Series 800W / 900W

User’s Manual

Thank you for choosing this X 7 Series power supply unit (PSU)! Please read this manual carefully and follow its instructions before installation.

Two unique technologies (interleaved PFC and phase-shifted full-bridge) can guarantee ultra-high efficiency. The smart fan of the segmented voltage regulator can create a very quiet environment. The pluggable terminal can make the wire cleaning more easily.

We would like to draw your attention to the conditions that your system works best for you without failing.

To make sure you connect your power supply properly, please check your motherboard and graphic card manuals for compatibility before connecting the power supply to any of your devices.

Chapter B: Installation

1. Turn off your computer; unplug the power cord from your old power supply.

2. Open your computer case following your case manual.

3. Disconnect all PSU connectors from the motherboard and the peripherals, such as cooler, HDD, DVD, CDR, FDD, etc.

4. Remove the old power supply from your computer case and install your new power supply.

5. Connect the 20+4 pin main power connector to your motherboard.

Note: Use the separated 20 pin if your motherboard requires 20 pin power connector.

6. Connect the 8 pin (4+4) connectors to your motherboard.

Note: Use the 4 pin or 8 pin is up to your motherboard

7. Connect the Serial-ATA connectors to the peripherals.

8. Connect the peripheral 4 pin power connectors if you are still using

IDE hard drives or optical drives.

9. Connect the PCI EXPRESS power connector to your PCI EXPRESS graphic card.

Note: Please read the user’s manual supplied with your graphic card for detail usage instructions.

10. Connect your cooler to the regular 4 pin peripheral connectors if you have.

11. Close your computer case and connect the AC power cord to the power supply.

Chapter C: Booting the system

1. Main power connector (20+4 pin configuration) is correctly connected.

2. CPU +12V power connector (4 or 4+4 pin configuration) is correctly connected.

3. PCIe connector (if required by GPU) is correctly connected.

4. All other needed connectors are correctly connected.

Incorrect insertion might cause your PC unable to boot and some components might even be damaged!

5. AC cord is correctly connected to wall plug and power supply AC inlet.

6. Then close your computer case.

7. Turn on the power supply by setting the I/O switch to “I” position; your system is ready to run.

8. Turn on your PC by pushing power button on your PC case!

Vin/Voltage 90 100—240 265 Vrms

Vin/Frequency 47 --- 63 Hz

1.1 Input over-current protection

The power supply shall incorporate one input fuse on the LINE side for input over current protection to prevent damage to the power supply and meet product safety requirements. Fuses should be slow blow type or equivalent to prevent nuisance trips. AC inrush current shall not cause the

AC line fuse to blow under any conditions.

1.2 Efficiency

This series power supply is high efficiency; it can reach 88% at typical load.

2.3 Output protection

If the power supply is latch into shutdown stage (when OCP ,OVP or short protection is working ),the power supply shall return to normal operation only after the fault has been removed and remote signal must reset for a minimum of 1 second (or the AC removed for 10 second) . Then, it will turn on again.

2.3.1 Over voltage Protection (OVP)

In case of over voltage limits are exceeded, the power supply shall provide latch-mode over-voltage protection.

2.3.2 Short Circuit Protection (SCP)

An output short circuit is defined as any output impedance of less than

0.1 ohms. The power supply shall shut down and latch off for shorting all output to GND.

2.3.3 Over Current Protection (OCP)

Overload currents are applied to each tested output rail. If the current limits are exceeded, the power supply shall shutdown and latch off.
