Originally posted by: Unknown Today, we obtained the failure rate of power supplies recorded by a major French e-commerce. These statistics include products in shops since the first April 2006.A minimum if at least 100 units have been sold. Statistics per brand are based on a minimum sample of 500 units:

Fortron: 0.7%
Hiper: 1.2%
Seasonic: 1.4%
Thermaltake: 1.6%
Tagan: 2.8%
Enermax: 3.0%
Antec: 9.5%

Fortron comes first in the list followed by Hiper and Seasonic. Thermaltake is next and is the last manufacturer to have an acceptable failure rate. Tagan, Enermax and most of all Antec are above the limit. For Antec the entire power supply range has very high failure rates: 21.6%, 18.1% and 17.3% for the Antec SmartPower 2.0 500, 350 and 400 Watts. Not a single product has a rate below 2% and the best one is the Neo HE 430 watts at 2.6%.

For Fortron, the figures are a bit more disparate from 0% for the most reliable model to 1.5% for the "least" reliable. Hiper's rates oscillate from 0.4% and 3.8%. The two models above 2% are the modular R 580 watts. For Seasonic, the leading products S12-500 and 600 are respectively at 1.8% and 0.9%.

Thermaltake's rates vary from 0% to 2.5% except for the Silent Power 680 Watts which is at 6.6%. Tagan's figures are relatively stable from 2.3% to 3.3%. Finally, Enermax' rates oscillate from 1.8 to 5.1% (Liberty EL620AWT).


Its unfortunate that they didn't have more tested brands. I would have been interested to see how brands like Ultra and Hipro would have ranked. Antec's figure really surprised me - I know that I'm not going to be recommending antec anytime soon .

Thats about as blinged out as Fortons they get. Its too bad they don't have any modular PSUs.

guess i was one of the lucky 90% twice then. my old truepower 480W and this truepower II 480W both work flawlessly. but yes, these numbers may compromise my purchase of another antec when i need another PSU...

I guess I am not the only one who questions these numbers. Without having a link to an official study, or more details than what is provided, it is hard to say if these "failure rates", lets take the antec for example, might include all units that were returned. How many of the units were actually tested by the distributor?

I guess that is my question.

Antec True Blue 480 Watts going on 3 years always on almost and never a problem. I doubt u can really base urself on these numbers since Antec is probably the biggest compagny in these therefore they produce many more PSU's then the other brands and even if they did only tske 500 as a sample it still makes them more of possibily.

I don't quite get what you're getting at; your point seems unclear to me. What does the number they produce have to do with anything?

I've never had a problem with any power supplies i've used.. be it a generic no name brand power supply, cooler master power supply, enermax, thermaltake or ultra... they've always worked flawlessly.. (and i leave my computers on 24/7) :S

my ultra 500 watt x-connect still powers my main machine and its been doing so for nearly 3 years now.. still works flawlessly considering the amount of component its powering..

Well i own a fortron, but from what other people said from NCIX, only the fortron 350-450watt power supply is really good and i own the 450W but the 500 one have a higher failure rate for its spec

It is a bit of an odd way to present failure rate figures. Failure rate is usually FIT's or Failures In Time. There's other ways, but to make sense of it there needs to be some background information provided.

Yeah, also the fact that companies do release bad batches from time to time, doesn't make them bad companies though

I can see the Antec numbers as opposed to the Tagan and other ones....I've had two of those go on me. One of those I can understand, the other is just the powersupply full out dying. The one I can understand was a 20pin Antec 380 hooked up to my 24pin Lanparty...held for about 8 months. The one I am blaming purely on Antec was my Antec 350w that had been working completely fine and all of a sudden I just started getting tons of BSOD's and what not....

Haven't had any of those problems with Epower.

I'm surprised to see Hiper so high up though...weren't those getting mixed reviews?

What strikes me as funny is the fact that they did not even do the top manufactures of computer today .
where is the failure rate for the HP , Compact , Sony , Dell and so on? I think this is just a bunch of BS really . as I have had a ton of PSU's in the past and only one has ever gone out on me and that was an Xconect PSU.

How was the sample done? How many of each were sampled? Where they similar quality? Seems strange that Antec was 9.5%. It should have been on 2000 units of similar quality supplies. Are the two best manufacturered in France by chance?

Well, from what i've seen HP, compaq, sony, and dell outsource their PSU's now.

My old compaq had a compaq psu, however my friend bill's had this 300w hipro in it. My friend pat's old dell has a fortron PSU in it, etc.

And for the record, after 3 years (right after i finished putting this compy together), my compaq psu died and i tossed in my friend's hipro and it has worked ever since in my old comp . lol
