Hi.

I recently moved to USA from Eu (PL) and took my pc parts with me. My question is regarding my psu (OCZ-ZS550W-EU).

Specs on it: AC Input: 230VAC, 10A, 50Hz

I know there's different voltage here in USA (120?). My friend told me that the psu has active pfc (??), so I can plug it in without any problems. Is this true? Or do i need to get a new psu ?

Regards

Works everywhere. Unless it says something else on your unit.

The OP's shows this:


Although to be able to get the 80 PLUS BRONZE certification, that is shown on its label, requires that it be able to operate at 115VAC.

There should be a sticker next to the AC outlet on the PSU. If the label specifically states AC INPUT: 220V, FREQUENCY: 50Hz then it is the fixed voltage model and should not be used with 115VAC mains. It has active PFC but is limited to / designed for 230VAC mains only.

Your label doesn't show the 80 PLUS Bronze certification so it is the fixed voltage model and will only operate at 230VAC, 50Hz.

the original box it came in states that it's 80 PLUS Bronze, and also states this:



i'm confused now... :sarcastic:

Active PFC:

The preferable type of PFC is Active Power Factor Correction (Active PFC) since it provides more efficient power frequency. Because Active PFC uses a circuit to correct power factor, Active PFC is able to generate a theoretical power factor of over 95%. Active Power Factor Correction also markedly diminishes total harmonics, automatically corrects for AC input voltage, and is capable of a full range of input voltage. Since Active PFC is the more complex method of Power Factor Correction, it is more expensive to produce an Active PFC power supply.

Is there a sticker beside the power supply units AC connector (i.e. assuming it hasn't been removed)? If yes, what is voltage specified?

Yes
AC INPUT: 230V , FREQUENCY: 50Hz

That indicates a fixed voltage model.

Having Active PFC does not guarantee universal input voltage.

You can contact OCZ and ask.

I called them and the tech told me that it'll work :hebe:  I'll just need to use a different power cable or a plug adapter :hebe: 

guess i'll just go and buy a new power cable, we'll see how it goes :sarcastic:

Well that's good to hear. I hope the tech is right.

Their use of different labels for supposedly the same product is pretty low class but typical of OCZ.
