Frequently Asked Questions - S12III500 SEASONIC

How to install my Seasonic S12III500?

Unplug the old power supply, secure the new one with the 4 provided screws, connect the modular cables (ATX, CPU, PCIe, peripherals) observing the keying, then plug in the power cord and turn on the switch.

The fan on my power supply is not spinning, is that normal?

Yes, in Hybrid or Fanless mode, the fan stays still until a certain load or temperature is reached. In Normal mode, it spins constantly.

Can I use cables from other brands with this power supply?

No, use only the provided Seasonic cables. Incompatible cables can damage the hardware.

How to test my power supply before installing it in the PC?

You can use a power supply tester on the 24-pin connector, or the paperclip method: short the PS-ON pin and a ground (see diagram in the manual) to start the unit without load.

What is the maximum power delivered on the +12V rail?

The S12III500 delivers up to 480 W on the +12V rail, which represents the majority of the total power.

What if my PC does not turn on after installation?

Check the switch position (I), the power cord connection, all connectors fully seated, and test the power supply with the paperclip method. If the motherboard is faulty, the unit will not start.

Is this power supply compatible with powerful graphics cards?

Yes, it has two 6+2 pin PCIe connectors. For a very demanding card, Seasonic recommends using two separate PCIe cables rather than a single daisy-chained one.

How to clean my power supply?

Unplug the power supply and use a dry cloth or low-power vacuum for the grilles. Never open the casing.

What is the warranty period?

The Seasonic warranty covers manufacturing defects. The exact duration depends on the seller and region; check the Seasonic website or your point of purchase.

Can I mount the power supply with the fan facing down?

Yes, in Normal mode. But check that your case has a ventilation opening at the bottom. In Hybrid mode, Seasonic recommends the fan facing up to optimize natural convection.

1. Remove your old PSU (power supply unit)

1.1. Disconnect your AC power cord from the wall socket and the back of the power supply.

1.2. Disconnect all DC cable connectors.
1.3. Remove all 4 mounting screws.
1.4. Remove your old PSU.

2.1. 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.

2.2. Connect both the 18-pin and 10-pin connectors of the motherboard cable to the PSU.
2.3. If your power supply features a fan control switch, set it to "Normal" Mode.
In Hybrid or Fanless Mode (S³FC) the fan will not turn.

Power Supply Tester

2.4. If you have a Power Supply Tester**, attach it to the 24-pin motherboard connector. There is a notch on the Tester that helps to make a perfect fit with the 24-pin connector.

** If you do not have a power supply tester, refer to the paper clip method described below.

2.5. (Optional) For testing a Fanless PSU or a PSU without the fan control switch, attach an external fan or LED light using a Molex cable to the PSU.

2.6. Turn on the power supply by setting the I/O switch to the "1" (ON) position.

If the power supply fan starts spinning (or the externally attached LED light turns on), then your PSU is working.

Paper clip method

Use a paper clip or a piece of wire to create a short circuit on the 24-pin motherboard connector by connecting the pins shown on the illustration.

3.1. 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.

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. There should always be enough clearance left between the PSU and the bottom case panel.

To learn about the ventilation of your computer case, please refer to the case manufacturer's instruction manual.

3.2. Flat Desktop-, SFX- or ITX systems

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.

3.3. Top of the case

Seasonic recommends the PSU to be mounted with its ventilation top cover facing DOWNWARD.

3.3. Top of the case

Mount the power supply with the ventilation top cover facing UPWARD only if there is enough space (at least 5 cm / 2 inches) available between the PSU ventilation top cover and the metal plate of the case, and only if the case has a ventilation panel on top.

4. Install your Seasonic PSU

4.1. Secure all 4 mounting screws.
4.2. Make sure the PSU power switch is in the "O" (OFF) position.
4.3. Select the fan control type if your PSU has this option.

Note: First power OFF the PSU before changing the fan control to take effect.

Hybrid Mode

Normal Mode

4.4. 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

Please make sure both connectors on the power supply side are properly connected.

CPU and PCIe Cables (8-pin connectors)

Peripheral Cables (6-pin connectors)

ATX 3.0 Compatible 12VHPWR Cable (16-pin connector)

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

Recommendations

Two PCIe power connector slots

Three PCIe power connector slots

ATTENTION! The intended use of the PSU is to power PC systems. For mining usage, please contact Seasonic for special cables.

4.5. Connect the AC power cord to the PSU. Plug the AC power cord into the wall socket.
