The new power supply is working but the device remains inactive?
The PSU is the final consideration when your PC fails to power on. After verifying all connections, you might want to test the front panel wiring by connecting the power button pins on the motherboard with a screwdriver to see if the system activates. What is the motherboard model? Is it a recent upgrade or an older unit that previously functioned?
I'm guessing it's the PSU since I've had lights on my computer that are separate from the motherboard, and they're not lighting up. Now I'm wondering if maybe the outlets are the issue.
Do you want an LED light to connect directly to the PSU without going through the motherboard? That won't activate until the PC or motherboard is powered on. Only after pressing the power button will the PSU fully start up. Until then, it only provides a small voltage for detecting the power button press and other minor functions. You could say it should light up after turning on the power button, but it might be because your power button wires are connected incorrectly. To test this, short those power pins on the motherboard as mentioned earlier and see if it works.
It is directly linked to the PSU, but the fan within the PSU remains inactive.
You have the ability to perform the paperclip test gently. This will reveal whether PSU outputs are delivering the correct voltages they should, and whether the device powers on, works properly, or if it's broken or dead.
If your chassis includes its own RGB controller, you can also check the LEDs using this approach.

Numerous instructions are available online by searching for 'paperclip test'.
Following the paper clip test on the PSU to verify it's functioning, reconnect everything and then detach the power switch connector from the motherboard, shorting it to check if the system responds.
As previously mentioned, verify all power connections thoroughly—pay special attention to the front panel connections.
Refer to the motherboard's User Guide and the case documentation; these details are crucial.
Keep in mind that the PSU supplies three distinct voltages (3, 5, and 12) to different system parts.
Indicating power is present doesn’t guarantee all components are receiving the correct voltage or sufficient power.
Do you have a multimeter available and know how to operate it? Or do you know someone who does?

This isn’t a complete test since the PSU isn’t under load.
Any voltages outside the acceptable range suggest a defective or failing PSU.
If testing isn’t feasible, replace it with another known working PSU and use only the cables that came with it.
