SeaSonic Electronics GX-1000W 80-PLUS Gold PCIE5 Modular Power Supply - Manual (Page 2)

2.1. Plug the AC power cord into the PSU. Make
sure that the AC power is coming directly from
the wall outlet.
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.
It is recommended to use a high quality surge protector to
protect the PSU and the system.
** If you do not have a power supply tester, refer to the
paper clip method described below.
2.2. Connect both the 18-pin and 10-pin
connectors of the motherboard cable to the PSU.
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.
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 “I” (ON)
position.
The drawings illustrate a fully modular PSU with a fan control switch and a Power Supply Tester; the features and
accessories of your PSU might be different.
If the power supply fan starts
spinning (or the externally attached
LED light turns on), then your PSU
is working.
