Failing power supply

In April 2007, I replaced a broken power supply in my PC with a Antec SmartPower 2.0 500W Power Supply. Check my review here. A few days ago, my pc has started producing a high pitched noise. Really annoying. So, I Google a little and what do I find: Antec SmartPower 2.0 500W Power Supplies apparently have 21% failure rate. Tell tale signs include the damn thing making high pitched noise.

I have to investigate a little further but probably this means the power supply is failing after less than one and a half year. Out of warranty of course. Damn it, really annoying to have to open that case again to replace the same part. Basically, the PC is now nearly three years old and maybe I should just replace it altogether. Something quiet, fast and reliable would be nice.

In a few weeks my new Macbook Pro should arrive at work (ordered yesterday). I was planning to wait and see if I like that and if so, just upgrade to a nice Mac at home as well. Not fully convinced yet.

Feel free to recommend a decent PSU. Has to power a Nvidia 7800, 2 drives, lots of USB hardware and a amd 4400+ dualcore CPU.

Update. I ended up installing a ZALMAN ZM600-HP. Seems to have a few good reviews http://www.tweaknews.net/reviews/zm600hp/. It’s expensive, over qualified for the job and supposedly really good and quiet. Sadly the rest of my machine is still rather noisy.

  1. The Finnish consumer protection law states that an item should last for as long as is reasonably expected of that kind of a product, regardless of what the warranty terms say. The manufacturer is responsible for manufacturing errors in the product, warranty period or not. Take the PSU back and complain, you should have a good case.

    On a side note, I’m never buying an Antec PSU again – three have failed on me. One broke my UPS when it went down, another spit sparks at me, third was found to be faulty after debugging mystical flakiness in unrelated parts of the machine.

  2. Hi Jukka,

    I should indeed bring back the psu. On the other hand, I don’t really want to wait for very long for a new PSU. Basically, I just want to get it over with. But no Antec, that’s for sure. So, I’ll just pick up a new one at verkkokauppa. Any tips?

    It’s in the machine for five minutes now and seems reasonably well behaved. Funny noise is gone, so my diagnose was correct. Now lets see if everything stays stable.

    Also, totally pointless blue led inside …. Whatever.

    But thanks for the advice Jukka.
