    Antec AR300 or AR350 to repair or replace

    Hi
    I have a dead antec AR300 from an Antec Aria case. Tried it with few motherboards, but its no go. Im planning to get an PSU tester in couple of days to check what exactly is dead in it.

    My quickest option would be to buy a replacement, but considering I have almost no budget to cover this I am going to try and fix it. Hopefully with your help
    If it's not fixable perhaps someone recommends a similar PSU with a decent price tag. These seems to be unique PSUs unfortunately with weird dimensions. We're talking (WxLxH) 15x8x13 cm but since it's L shape, the length has dimensions of 4.5cm and 8cm and the height has 13 and 9.5cm.
    And the power socket is actually outside its box, has 3 cables that come with it to an external socket.
    Perhaps picture can explain more.

    Hi Zing
    Welcome to the Forum!

    I had one of those Aria systems once. I never did take the PSU apart on mine.

    The Power Supply is completely Proprietary and unique to the Aria / NSK1300. You will probably not be able to find a similar one from anywhere but Antec. If it's still under Warranty, contact Antec. Do NOT open the PSU or damage the warranty sticker.

    If it's NOT under Warranty.....
    Your chances of repair aren't impossible.
    "PSU Testers" won't tell you much of anything. They are usually just a set of voltage indicators, which won't tell you anything at all about Voltage Ripple, Current capability or most especially, what might be wrong.
    The disassembly and soldering is relatively simple in a PSU. The boards are usually single-sided and easy to service. (compared to a multi-layered Motherboard for example)

    It is probably loaded with bad caps, probably purple ones from a company called "Fuhjyyu".

    Usually, bad caps won't prevent the PSU from starting, but it is possible, especially if small ones on the 5V standby circuit have failed.
    Also, the fuse might have blown. Of course many other things could have broken as well. You are going to have to find out.

    So, you're going to have to open it up and look inside. Probably you'll see a bunch of purple and white capacitors with the tops all bulged and split, maybe leaking out a little brown gunk.

    Fortunately, BadCaps.net can sell you appropriate capacitors to replace them with but you will need a list. I recommend replacing all of the caps except for the really large "Primary" caps. You are interested in the following for your shopping list:
    Capacitance, usually in uF (MicroFarads)
    Voltage, in V (Volts)
    Capacitor Brand and Series ex: Fuhjyyu TM
    Temperature in Celsius (usually 105C)
    Diameter in mm (usually 10mm or 8mm in Antecs)

    A common capacitor in an Antec PSU would be: Fuhjyyu TM 3300uF/16v 105C., 10mmx30mm. This is a supposedly "Low ESR" cap of atrocious quality. Badcaps offers the Samxon RS 3300/16 in 10mm which would be a suitable replacement.

    Good Luck with that one!

    PS. You might want to consider replacing the Aria and its proprietary PSU with a more conventional MATX case with a standard ATX PSU.

      I was that close to buy a Aria case few years ago. But I chickened out when I saw how odd this PSU is and no room for tall heatsink under that.

      Cheers, Wizard

        good advice.
        see if antec will rma it.
        iirc those things blow up grandly when they fail.
        more than just caps.
        does it pass the sniff test?

          to be honest guys I am new to all this.
          It was unfortunately a second hand one and the guy before me apparently open the PSU and fiddled with it. Nowonder its dead.
          The board is rammed with all kind of fuses and caps. I am not quiet sure I can play with it.

          I am trying to find a cheap PSU with same dimensions or close enough to fit in this box. So far I found one on ebay

          http://cgi.ebay.ie/300w-Micro-ATX-Po...1%7C240%3A1318

          I might be able to get it fixed in the back where the old one was.
          It will be less work for sure. A hassle? maybe.
