Frequently Asked Questions - Focus GX850 SEASONIC

Can I use modular cables from other brands?

No, use only the Seasonic cables provided with this power supply to avoid any risk of short circuit or damage.

The power supply does not turn on, what should I do?

Check that the power cord is properly connected, the switch is set to I, and the electrical outlet is powered. If nothing happens, toggle the switch several times with a 0.5 second delay.

How to install the power supply in the case?

Place the unit in the designated location, screw it in with the four screws provided, and plug in the appropriate modular connectors (motherboard, CPU, peripherals) respecting the keying. For a fan facing downwards, ensure the case has a ventilation grille.

What is the warranty of this power supply?

Seasonic offers a 10-year warranty on this model, covering manufacturing and material defects. Terms may vary by region.

Can I open the power supply unit to clean it?

No, never open the power supply unit. This voids the warranty and exposes to dangerous high voltages. Clean only the exterior with a dry cloth.

What does 'pull' technology mean?

The power supply only supplies the current requested by the components. If the motherboard or a peripheral is faulty, the unit will not start or will not power that component.

My power supply makes a constant fan noise, is this normal?

The fan is thermally controlled. If it runs constantly at full speed, check that the ventilation openings are not blocked and that the ambient temperature is not excessive. A humming sound may indicate a defect, contact support.

Can I use this power supply with an old motherboard?

Yes, it is compatible with ATX12V 2.4 and EPS12V 2.92 standards, so backward compatible with most recent or old ATX motherboards, provided you use the correct 20/24-pin connector.

How many PCIe connectors are available?

This power supply has 4 PCIe 6+2-pin connectors, capable of powering up to two high-end graphics cards.

What to do if a modular cable is lost?

Contact Seasonic customer service to order replacement cables. Never use non-official cables.

III. Power Supply Removal

1. Please first read Chapter II. Warning! Important Safety Information above.
2. Make certain that your system is entirely powered off; set the power supply's AC power switch to the "O" (OFF) position and disconnect the power cord from the AC outlet.
3. Open the computer case (please refer to the manufacturer's user manual).
4. Carefully disconnect all the power supply's connectors from the mainboard and the peripherals.
5. Unscrew the mounting screws securing the power supply unit to the back panel of the case.
6. Carefully remove the power supply from the case.

IV. 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.

a. 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.)

b. 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

1. Mainboard connection:

a. 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.
b. Connect the power supply end of the 24/20-Pin convertible connector to the appropriate receptor on the power supply unit.
c. 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.
d. Connect the +12V 4-Pin connector and the EPS + 12V connector, if applicable.

e. 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.

1. Peripheral components connection:

a. Connect one end of the peripheral cable to the power supply and the other end to the component.

b. DO NOT use excessive force to attach the connectors; the connectors are "keyed" so they can only fit one way.
c. Make sure that the connectors lock in tightly and securely.

1. Close the computer case according to the manufacturer's instructions.
2. 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.
3. You are now ready to start your computer powered by Seasonic.

V. Troubleshooting

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

1. Check to make sure the AC power cord is properly connected to the AC source and the power supply unit.
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 "1" (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 "l" 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.
