Windows Forum / Windows XP / Hardware / October 2006need atx-ssi power supply recommendation
Hi All, If you needed to spec out a 550 watt (or some such) ATX-SSI power supply that had to last at least eight (8) years, which one would you spec out? Must be long lived and very high quality. Many thanks, --Tony It is impossible to spec out ANY component that will last 8 years, there is 100% NO way to tell how long a component will last, and claiming that you can will impress no one when it fails in a year and a half. > Hi All, > [quoted text clipped - 5 lines] > Many thanks, > --Tony > Hi All, > [quoted text clipped - 5 lines] > Many thanks, > --Tony The best power supplies I have used are the PC Power and Cooling ones. I have one that is still going strong after about 8 years. They cost more than the ones you can buy at the local stores but they are also one of the oldest companies in the business, having been around from the early PC times. > > Hi All, > > [quoted text clipped - 11 lines] > of the oldest companies in the business, having been around from the > early PC times. Thank you! Nothing is warranted for longer that one year. If you need a power supply that absolutely must last eight years, you had better learn electronic design and build it yourself.

Hi Richard, Check out http://www.pcpower.com/products/viewproduct.php?show=S61EPS "3-year warranty and support" -T Yes, and I have had some last 5 years. So what! You are not going to get any warranty for 8 years as you seem to need/desire. That would be military grade electronics and you couldn't afford to pay for it.

Who asked for a warranty? Maybe I should reread what I asked: If you needed to spec out a 550 watt (or some such) ATX-SSI power supply that had to last at least eight (8) years, which one would you spec out? Must be long lived and very high quality. Nope. Didn't ask for one. Hmmm. I was asking for recommendations based on other peoples experience though. If you do not know, please do not answer. -T Until SOMEBODY jumps off the "race-to-the-bottom/ all-everyone-wants-is-the-cheapest-possible-price" (aka the Wal-Mart effect) bandwagon, and starts the manufacture of long-lived brushless DC fans (the only moving part in a PSU), it will never happen. The ELECTRONIC components of a PSU will last the 8 years required. The el-cheapo fan will not, and when it fails, the other PSU components, now being operated outside their nominal temp. limits, will die. There are auto-switchover/redundant PSU cases available, I saw them once while looking for something online. Two identical PSU's in one case, with auto-switchover circuitry, when one PSU dies, you are notified that it has happened, the system changes over to the "good" PSU, you hot-swap out the bad one... > > Yes, and I have had some last 5 years.

The other option is to get a high quality power supply with no fans. The fans in the PC Power and Cooling do seem to hold up better than the generic ones though. The one I have still working after all these years is running 24x7 and the computer is sitting on a carpeted floor. No problems with the power supply or fan. > There are auto-switchover/redundant PSU cases > available, I saw them once while looking for something [quoted text clipped - 24 lines] >> >> -T I do not know of any I can guarantee to last 8 years.

Even with all of the above, if the supply is on all the time most likely the fan will fail long before you reach 8 years. It also would not hurt to talk to the manufacturer and tell them your requirements.

Unnecessary if the unit is properly built and kept in a clean environment. I wonder if the power supplies used in the AIX series of computers could be used in a PC? I have an RS/6000 that is still running on the original power supply after more than 10 years. >> Then I would upgrade to an 800 to 1000 watt supply so that the supply is >> lightly loaded (25 to 35% of full capacity), has a top quality variable [quoted text clipped - 17 lines] >>> Many thanks, >>> --Tony > > What I mentioned earlier: > > [quoted text clipped - 6 lines] > computers could be used in a PC?

Fans will STILL die, unless you can find good ones, such as the ones (apparently) your 10 yr. old PSU has... There are "maglev" fans now available, which "float" the rotor/blades on a magnetic field, which show promise as far as longevity, but I've not been able to find them any larger than 60mm (most PSU fans are 80mm). > >> Then I would upgrade to an 800 to 1000 watt supply so that the supply is > >> lightly loaded (25 to 35% of full capacity), has a top quality variable [quoted text clipped - 17 lines] > >>> Many thanks, > >>> --Tony >>> What I mentioned earlier: >>> [quoted text clipped - 9 lines] > Fans will STILL die, unless you can find good ones, > such as the ones (apparently) your 10 yr. old PSU has... Anything will die with time, the trick is to get something that will not fail after the 90 days warranty expires like I have seen with some fans. Also the cleaner the environment the longer they will live. Our remote office that is surrounded by desert goes through power supply fans a lot faster than the computer room in our main office. In fact I don't think I have had a fan failure in the computer room in more than 10 years. > There are "maglev" fans now available, which "float" > the rotor/blades on a magnetic field, which show promise [quoted text clipped - 26 lines] >>>>> Many thanks, >>>>> --Tony > Hi All, > [quoted text clipped - 5 lines] > Many thanks, > --Tony PC Power & Cooling is the best. http://www.pcpowercooling.com/home/ |
