Just bought new power supply but was smoking when first turned on pc runs fine

[Zzzzzzz]

I just bought a new power supply but when I first turned it on there was smoke not weird noises just smoke. I’ve already checked all the connections, I do have extension cables but they’ve worked great in the past. What should I do?

Edited March 19 by Zzzzzzz
Update: Also makes a clicking sound when I turn off the pc I’ve never heard that in any previous power supplies

Modular power supply? If yes, did you reuse the old PSU cables?

Used new cables with new power supply

That's really unusual so I'd double check all your cable connections are snug and correct before turning it on again. Do you happen to know where the smoke was coming from?

[Zzzzzzz]

I do not know exactly where the smoke is coming from

Can you list your PC specifications, including the old and new make/model/wattage of the power supplies?

You're gonna have to tear down the PC and determine if there are any burnt connectors or burnt marks on PCBs (printed circuit boards) such as the motherboard, graphics card (at least on the back where the backplate would be). Use your nose and waft your hand through the air the smell (as if your smelling cooked food) on each component to try and pinpoint where the smell, and possibly damage, is located.

If it actually came from the PSU, I wouldn't even turn it on again.

 

It might be working, but some component could have been defective from the factory and is no longer doing its job any more which could cause further damage to anything else connected to the PSU over time.

The first place I would check for any kind of weirdness is the power supply, since that's where the smoke appears to have come from. You might have to get personal with it, but you'll need to look at it at all angles to see if any damage is present.

 

Otherwise, return the power supply, and inspect the rest of the build to see if anything else looks damaged.

No damage seems to be present to any components

If it came from the PSU, you wont be able to see that.

Decided not to as it’s a new power supply, my last one failed almost the same way, and voids the warranty

You might be able to see something by looking through the grille of the power supply, and through the fan. No need to disassemble it.

No damage inside the psu that can be seen

I think that even with no visible damage present(based on what's visible), I would return your power supply to the manufacturer and allow them to either investigate it, or give you a new unit. That to me is the best thing to do in this scenario.

This was what I meant, if you can't see visible damage anywhere and the smoke came from the PSU then it doesn't matter if you can see it, clearly something IS burnt in the PSU.
