Poll of the Day > Accidentally moving the computer PSU switch from 115 volts to 230..

(+) Yeah! (+)

While its running, while in the US means i just killed my power supply, right?

Try to turn it on, see what happens.

I don't think it will blow anything, but, who knows.

Pc won't turn on but i do get a split second of action before it just dies.

Sounds like it's fucked, yup.

Potentially there's a fuse in there that's blown, but, unless you know what you're looking for, I don't recommend opening a PSU, there's stuff in there that can kill you.

God damnit. This is what i get for fiddling with things in the dark.

So in this case somebody recommend me a new PSU

That shouldn't have damaged anything. You basically told the PSU to expect a 230V input and you were only giving it 115V, so you were under-volting it.

All my pc does is sometimes lights will turn on for half a second but then it shuts off. Stuff like the Ethernet port light stays on if i have it plugged in for whatever that is worth.

I easily could have fucked it up in the fiddling to fix the issue but it wouldn't turn on today regardless

It's also AC which means you could have different amperage running through things that weren't expecting it, and there's an unexpected frequency on it.

It's not as simple as a DC voltage.

I am a moron. I did fuck with the voltage switch, but why it wasnt working is due to my own moron ass not knowing how to read the swtich.

When I move it from side to side it either says 220 or 115. I thought, when it said 115, I needed to move it over to go to 115, as if there was a directional arrow(there wasn't). turns out if the switch says 115 that is the one chosen.

So we are good. I am an idiot. I am closing this shit 'cause i feel dumb.

Ahaha, I'm happy they have built in protections then and it was just your system being upset.

For example

I figured to get 115 volts I needed to slide the switch over to the left. Turns out if it says 115 its at 115

I'm not super technically literate once we start talkin' fancy science things.
