Hey all :)

I was upgrading my PC yesterday with an Nvidia 670. It was all plugged in (aside from one power supply connection). It was then that I realised I needed to change my power supply. A bit silly, I know, I know. Let's not go into it here. Anyway, I went around the back of the PC and completely forgot that the power was still plugged in. It was then that I saw a small red switch which said 230V but it was half on, which I thought was a bit odd. I thought it might be dangerous to have it on halfway and so flipped it, thinking it would be okay. The next thing I knew, there was a spark inside the power supply and now it won't switch on at all. I believe the power supply has been fried, but I'm worried about the other components, like the Nvidia 670 which cost me £300!

Do you think everything has been fried, or is it just the power supply?
If the components have been fried, would Nvidia replace the brand new graphics card?

Could be just the power supply, that switch sets the voltage for either 115 volts if you are in North America or 230 volts if you are in Europe. The only way you'll know is to test it with a new power supply, and it should be a quality brand 600 Watt if you are using the system for gaming with a Geforce GTX 670.

I'm in England, so I'm guessing it's 230 volts. I guess I'll have to save up my pennies and buy a new power supply as soon as I can and then test it that way. The power supply I have at the moment is only a 550 watt and well, like I said - it's as dead as a dodo :/

If it was a good quality power supply your motherboard and other hardware should be fine. Quality power supplies have over-voltage and surge protection that should stop the surge from spreading to the motherboard.

That's the thing... I'm not really sure if my power supply is a good quality one. My Dad bought it for me when I was upgrading my PC two years ago from a trusted local hardware supplier. He sold us another Octigen power supply that was 550 Watts and said it would be okay for the system I was trying to build (which it was). But as I said... I made one small mistake and now I'm worried that the brand new £300 graphics card might have just blown up :/

It was powered up when it happened, yeah. I think so, anyway. The only power supply connections that weren't plugged in were the spare ones that usually plug into the graphics card. Well, I had one plugged into the graphics card because that's all that was available with that power supply. Hopefully that makes sense... it's getting near 5pm so naturally sleepy time is nearing haha.

I'm looking at the reviews and a lot of people are saying that that particular PSU breaks after about 4 -8 weeks of normal use, which isn't really good to be honest.
