Computer power source help!

Hello everyone I just moved from TX to HCMC with my family for work. Unfortunately my computer does not have that switch by the power source to switch between 120v and 240v. Does anyone know where I can get a quality converter/transformer? I have seen cheapies on Amazon and elsewhere but I would really not like to risk ruining my computer.

Can someone point me in the right direction?

The cheap stuff leaves you prone to big and expensive problems.
Just pop to a decent computer shop and get a new PSU in the thing, a proper one that'll work between 110 and 240 volts as is available in the whole world except, it seems, for the US of A.

Would you be able to recommend a good computer shop that knows how to switch the power source out? I have only been in town for a couple of days and have no clue what is decent or not.

Hi,

Try Phong Vu (phongvu.vn) at 198 Nguyễn Thị Minh Khai, Phường 6, Quận 3. I bought a PSU there, a Coolermaster, as they had a good range to choose from. I am not sure if they can install it for you though.

Check the power adapter/pack to see if it's a 100-240v 50-60 hz ac/dc.  If it is, try plugging it into the top 2 holes of the standard 3 prong outlet.  It will probably fit and you should be good to go, but if you don't feel comfortable trying it out, go to the shop another member suggested - Phong Vu (or any of the hundreds of shops in Saigon) and watch them plug it in and possibly (probably) have a laugh at your expense.

If it's not an ac/dc adapter, then you only need one of those, not a transformer.   Phong Vu is as good a choice as any.  Phong Vu

I don't know any computer that is not a dual voltage.  Even the dinosaur Dell desktop which I moved from the States to Europe and back two decades ago worked in both voltages automatically, with only a plug adapter needed for the various Italian outlets.

Is there still one that doesn't work in all regions?

My computer doesn’t mention anything about being dual voltage but you got the wheels turning in my head. It may have that ability. I’m going to look up the specs and see what it can do. Thanks for the advice.

if someone someday needs a power converter for their "pure 110V machines" bought from the USA. You can buy it from "VN amazon"

or if you look hard enough you can find it in "Nhat tao" (tp HCM electronic area)

MAX 18A for 110v.

Those two devices convert 220V to 110V, not 110V to 220V as you said.

Description for the first one: 
220V to 110V: 
This converter is perfect for most small electronics from 100~120 volt countries such as USA, Canada, Japan to be used in 220 volt countries. 
Input Voltage: AC 200~240V -- Output Voltage: AC 100~120V

Description for the second one: 
220v/240v to 110v/120v. 
Input: AC 220V/240V -- Output: AC 110/120V 50/60Hz

Houston we have a problem

What about watts?

These show as 200w - not a lot for a desktop computer so very possibly useless unless the OP likes a nice warm real fire, or at least a singed table.

OP - Take a nice clear photo of the PSU's label and post it here - we can tell you in a flash - before you get a flash and a bang.

It's likely to look something like this - the input voltage is the bit that matters as far as plugging it directly in goes

The max power is the bit you need to think about if yo use an adaptor.

yes i said/mean "The two devices convert 220V to 110V", for us equipments
>>MAX 18A for 110v.
take the two links as an example, you can buy a convert which  can handle more Ampere

you don't need to, your laptop runs "x" voltage, normally around 19 and a certain amps. take a pic of ur current 1 then when u get here, look for the same factors on the new transformer

Just to clarify. These transformers can NOT be used with ANY electronic equipment, including computer power supplies. (Though I am sure his computer is dual voltage/hertz).

These transformers only convert the voltage, but not the frequency of that voltage. That's why in the description above is says "AC 110/120V[/b] 50/60Hz" The 50/60hz means what it takes it, it gives out. In Vietnam and most of the world, it's 240 V and 50 hz; in the USA it's 120 V and 60 hz.

There are transformers that convert both, but they cost more than $3,000 US.

So, in sum, if you actually do have something that uses 120V only, it's cheaper to just replace the item.
