Thread: Power Supply

I bought a computer and its got a 110 V power supply.
Well i got a new graphics card. and i went to change the power supply via a switch on the back of the computer says 220 V i think.
Well when i switch it, it doesn't let me boot up my computer any more. Any sugguestions?

You're not supposed to change that switch - it tells your PSU what kind of outlet it was plugged into.

so, i would just need to buy a new power supply all togetheR?

mine does have a switch to go to 220 V but it just won't boot up

I guess i'll just buy like a 350 V

Try putting the switch back to 110 and turning it on. You should never touch that unless you're plugging it into an industrial outlet or something.

edit: You obviously don't understand. The switch doesn't have anything to do with the rating of your power supply

it works at 110 V but i need more!!!

You don't need more voltage, big guy. If your PC can't run with the new graphics card in, you need a PSU with more wattage.

lol, that's what i was thinking of wattage not voltage. I'm the biggest tard on the block.
yeah i guess i am going to buy a new power supply then. I do LOTS of gaming. Thanks!!!

ah. So, normal outlets put out like 110 volts?

The switch on the back of the power supply is for what is being INPUTTED into the power supply. Output from the power supply is not measure in volts but in watts (as far as selling is concerned).

That's what I've been trying to say.

And yes, a standard wall outlet puts out ~110V AC. Industrial strength outlets put out 220 or so.

ah, thanks for the clearing up.

There's the link about volts, amps, watts, ohms in this web site:

Er, to clarify, that may be the case in the US but is certainly not the case in many other countries.

In Europe for example, standard power outlets deliver between 220V and 260V depending on the country, and at 50Hz, whereas I believe in the US it is 60Hz.

Specialised industrial outlets here can be as low as 110V or multiphased up to 475V.

I would advise anyone NOT to fiddle with the VOLTAGE settings on their power supply unless they really understand what they are doing.
