110/220V input question with Antec PSU Tags: Power Supplies Switch Antec Components Product Last response: January 9, 2008 7:58 PM in Components Share keplenk January 9, 2008 3:51:18 PM Hi, I just recently purchased an Antec earthwatts EA380 ATX12V v2.0 380W Power Supply as advised by the forum members here (thanks by the way). here's the newegg link: http://www.newegg.com/Product/Product.aspx?Item=N82E168... I don't have the PSU yet (still in transit) and I was just wondering about the input voltage. I noticed that the PSU doesnt have a switch to change it from 110v to 220v or vice versa. My previous PSUs has this switch. I only based this info from the Newegg pictures. I'm in the US right now and they use 110v ... I'm going back to my home country next week and we use 220V there. When I checked the specifications it says: Input Voltage 100 - 240 V Does this mean its AUTO Volt? or do I have to do something else first. like a switch or something. Its actually not a biggy because the UPS I use has (1) 110v plug and the rest are 220v. But I just want to be sure because someone could accidentally plug it to 220v. 1) Is it safe to just plug it in 220v? 2) Let's say I can use either 110v or 220v: Is it better to plug it into 110v or 220v? If I use higher voltage, does the power supply lifespan shortens? *If you use 220v, will it stress the power supply more? THank you very much!

THanks for your reply I will use the higher voltage semi-Off topic: I found some interesting things when I went to the Antec website. I just found some discrepancy between the info from Newegg and the Website. The Antec Website states that there is a voltage switch http://www.antec.com/specs/EA380_spe.html Also, the voltages in the dual 12V rails are different from the website and Newegg. from the website it says: +12V1 = 17A and +12V2 = 15A Newegg and the Sticker picture says: +12V1 = 17A and +12V2 = 17A http://www.newegg.com/Product/ShowImage.aspx?CurImage=1... Weird .. I'm pretty much sure I clicked and search the right Antec EA model But anyway .. thanks for your help Related resources PSU Input Question: Correct Cable ? - Forum Amp input question for XFX 750W PSU - Forum Antec VP450 Input switcher - Forum 3 "easy" newb wiring questions?

In other countries the wall socket operates at 50hz, 70hz, etc. Check the psu, if it only says 60hz, it will explode. evongugg January 9, 2008 5:03:47 PM Quote:Also, the voltages in the dual 12V rails are different from the website and Newegg. from the website it says: +12V1 = 17A and +12V2 = 15A Newegg and the Sticker picture says: +12V1 = 17A and +12V2 = 17A Probably an updated version of the power supply. When I send back to Antec a PSU, they usually send me one with more amps on the 12v rails. keplenk January 9, 2008 5:16:12 PM surrealdeal said:yes, it will auto switch. BUT...

Can this information be found on the UPS that I use there? Thanks EDIT: The Antec EA380W has this specification in terms of Freq Input Frequency Range - 50/60 Hz Is it safe? Our country uses 60hz .. when I googled it ... I'm not yet sure if its true or precise I got it here: http://www.iagora.com/itravel/tools/conv/electric_cnv2.... surrealdeal January 9, 2008 6:09:27 PM http://en.wikipedia.org/wiki/List_of_countries_with_mai... That's a terrible source of information, but all the good sites make you pay 1000's a year for their info. You should be fine. keplenk January 9, 2008 7:58:16 PM Yup, its really 60hz in my country.
