Convert 220 to 110 Help

jampeng · Sep 8, 2013

So this is the problem i have a 600watts PSU that has 220V but the elevtric current in our place is 110v what do i need to convert 220v to 110v. i know that transformers can convert 110 to 220 but i cant find transformers in our place. and a followup question if a UPS can convert 220v to 110v because i saw a lot of ups.

thanks in advance

There should be a red switch that you will need to flip and set it to 110v. It should be able to run on either depending on which switch is flipped.

Yes, step-down transformers can convert a higher voltage to a lower voltage, but they would probably cost more than replacing the PSU with one of the correct voltage. Same with UPSs. Does the PSU have a voltage selector switch that you can use to change it to the lower voltage? Some do. What is the make/model of your PSU?

Most power supplies are capable of 100 - 240V. The older power supplies have a red switch on the back that you can use a screw driver to select what voltage range you are in (120-100 or 220-240). The newer power supplies are automatic in this regard.

What's your power supply model ? You can look it up on the internet to see if it has a full AC range input (100-240) or a regional only AC input (220 only). You can also see if the sticker on the power supply inside the case says what the AC input voltage range is. It will usually be listed on that sticker. If it says 100-240V or equivalently, 110-220V, you are good to go (if there is no red switch on the back side).

You might want to go check your PSU's manual.

PSUs that do not have a 115/230V switch are usually universal designs that have an input range starting as low as 90V going all the way up to 250V.

If you want an UPS that does voltage conversion, you would be looking at somewhat fancy double-conversion models often costing over $1000 so it would be much cheaper to simply get a new PSU if you are genuinely stuck with a 220V-only PSU.

the psu is 220 because it has sticker on the back that shows 200 - 240 vac and it doesnt have switch to convert it to 110. my psu is Aerocool 600watts modular psu.i was thinking to buy another psu but my problem is i cant the find psu models that i want to replace my psu thats why i am asking if a ups can convert a 220 to 110.and if i look for a transformer how many watts of transformer should i get to sustain the wattage of my psu

if it will cost me a lot if ill buy a power converter or a ups i think im going to replace my psu. sad for me

i cant get the model that i want.

If this is your PSU: http://www.aerocool.us/strikex%20power/strikex_power%20600w.htm
...it will accept 115 - 230V. Have you tried it?

jampeng · Sep 8, 2013

yeah that is.but it say in the AC input voltage 230v its not 115 - 230v

jampeng · Sep 8, 2013

i really love this psu because its modular and 80+ bronze. but i guess i really need to replace it right?sad for me

What kind of plug does it have on the end of its cable?
120V: http://www.horticulturesource.com/images/1outlet120power.jpg
or
230V: http://images.office365.co.uk/pim/714902.jpg

jampeng · Sep 8, 2013

actually i have both of those plugs.which of those plugs that i need to use??

Well, if your PSU doesn't indicate 110V compatibility, then it would be ideal to get another power supply. You can easily get 80+ Gold or Platinum power supplies these days, and from a much more reliable brand than Aerocool.

I think this is your PSU, with only a 230V rating, right ?

It is a Taiwanese brand that doesn't seem to have a large presence in North America.

Here is what Kitguru said about the Aerocool Strike-X 800W power supply (your 600W model should be similar):

"Initially we thought this was a Hiper design, but it appears to be manufactured by Andyson – a company we haven’t rated that highly going on past experiences"

"The construction/soldering quality of this unit isn’t bad and it is using Teapo electrolytic capacitors throughout the design. We aren’t big believers in Teapo capacitors as we have experienced failures in the past."

From: http://www.kitguru.net/components/power-supplies/zardon/aerocool-strike-x-800w-psu-review/4/

This is the image of the Teapos

I'm not fond of those capacitors. I have had to fix half a dozen power supplies with bad Teapo capacitors in the past.

I think it would be a good idea to replace your PSU anyway, given what's inside. I would recommend a Seasonic or Corsair.

I wouldn't be too worried about hanging onto your PSU - Aerocools are very mediocre power supplies. Aerocool's a tier 4 brand and many of their PSUs have issues with ripple protection. The Strike-X Aerocools are a little better, but very, very average - here's the conclusion from KitGuru's evaluation of a Strike-X 800.

"The Andyson design delivers decent load regulation and it dealt with our cross loading test without falling over, although we have seen much better from other units recently. The fan performed well, however it has to spin quite fast in the last 30% of power output and is clearly audible even over several chassis fans. At full load it generates a noticeable noise emission.

The unit failed the ripple suppression test, peaking at 65mV on the +5V output. The other rails held within the official tolerance guidelines, although they were all a little higher than we would like to see.

The unit didn’t fail in our ‘real world’ testing this week, but we would have some concerns with the overall noise suppression capabilities, especially if the end user was pushing the supply hard, particularly when overclocked with expensive, high drain partnering equipment. I wouldn’t trust this unit long term with a high end system build.

The efficiency of the AeroCool Strike-X 800W was also disappointing, especially at lower wattage demands."

In other words, not a terrible PSU, but not one to cry any tears about if you replace it.

(Coke to Maxx Power, the man with the name you'd love to touch, to beating me to the Kitguru review)

jampeng :

But you mustn't touch!! Cheers! Thanks for quoting the summary too!

clutchc · Sep 9, 2013

jampeng :

If the PSU came with separate 120V and 230V cables, it probably auto-switches depending on what voltage it is connected to. Use the cord that matches the outlet you want to plug it into.
