PC turns on when PSU is off

[Ash Champ]

So the O/I switch on the PSU apparently is irrelevant as my PC turns on when either one is turned. I have no clue why that is so any help would be much appreciated.

 

system:

SF600 corsair PSU

SG13 case

1070

11400f

Picture shows PSU on O position (off) and lights and pc is on

If the PSU is on with the switch in the "O" position...then I'd start to question whether the rest of the PSU was put together properly (sounds stupid, but I have my reasons).

Would it be dangerous to power it on again?

I would immideately swap that psu out, because this is really a fire hazard

I agree, nothing is perfect. If you are comfortable enough to do so, open up the psu and check that none of the cables are detached or look to be in the wrong place. If you still have warranty (which I doubt) or if you are not willing to open a psu, just get a new one instead.

They probably put the wires on on/off button incorrectly, the wrong way.

 

The button is a 2 state   (O) x---x---x ( I )    one wire is on the center contact , the other wire goes to one of the side contacts , one for O and one for I. 

When you press the switch, one side disconnects and the other side connects.

 

if they soldered the wire to the O pin then the button will turn on the power supply when the switch is  set on O.

If the PSU still has a warranty or within a return window, I'd rather have the OP RMA or exchange it out for a new one, respectively. You do NOT want to open a PSU unless you have knowledge in electricity and how it works. There are main capacitors that still hold residual charge after unplugging a PSU and can shock/kill you.

Unfortunately they are both ‘on’ switches as neither of them turn the psi off

I have contacted Amazon and have ordered a replacement since I bought it couple weeks ago. Thanks for all your advise

I don’t think the PSU will have damaged any of the components but better safe to check. Does anyone know how to check if a component has been affected by the PSU?

Yes, which is why I stated that if it still has warranty or if they are uncomfortable with opening a psu that they should just replace it.

Since it seems you are very unsure of what to do, I would recommend just leaving it alone.
