PC Peripherals THG: PSU Live Stress Test

Seeing coolermaster and ocz both failing and also the thg reputation being suspect as ever, i have a wierd feeling that its thg to blame.

@Sunny: ocz is rebadged Tagan which are very good psus.

Wonder if THG has any plans to test Powerstream 520W at some time ? Seems to be very popular - in some respects even more than the 600W !

And yeah, if THG is at fault it's reputation or whatever is left of it is sunk forever !

I'm waiting for Round 2 of Antec. There is this theory that cross-loading may have caused out-of-spec ripples on +12V.
 
If you had been following the THG Munich website over the past week, you may be aware of this already - On Take Two the Antec TP Version 2 made the grade. The Summary was posted on THG US wesbsite today.

The rationale for Antec's out-of-spec ripples is sketchy, but THG appears to have been convinced by the demo from the Antec engineers who visited the test site at Munich. On retest, the ripples seem to be well within specs (hmm....).

Important Update - Antec technicians from Taiwan and the USA visited the Munich THG laboratory for just this purpose. The reason for the 3-hour visit was the divergences we discovered in the ripple test, which were not within spec - although the power supplies did not fail. The technicians from Antec performed new ripple tests on their power supplies together with the THG laboratory engineers. It turned out that the tolerances and high-frequency vibrations with their PSU can lead to varying results in the ripple tests. However, we didn't observe this phenomenon in any of the other candidates.

Because we determined that the ripple tests can remain entirely within spec in the present models and that the other values were flawless, the Antec devices still earned positive test grades.

And an interesting bit of info from THG on the state-of-affairs on PSU pricing:
Still An Eldorado? 600 Percent Profit Margin Possible

After all, power supplies currently represent one of the highest margin segments in the market. We have information from reliable sources that in certain cases margins are being obtained in the high triple digits for devices purchased directly in China. Other peripheral PC components do not afford comparable profit margin, with the exception of cables or plugs, which can even bring in several thousand percent. The sample computation below demonstrates emphatically the price inflation that occurs between the few dollars paid in China for purchasing and the price consumers pay. This is a factor of several 100%, most of which flows to dealers and retail sellers. It should be remembered however that the risk of product defects and warranty claims is borne by the purchaser. Optimal profitability is obtained through direct purchasing in China in combination with high unit volume. This lowers the purchasing cost of power supplies to just a few dollars. The table below provides an example of the individual prices.

300 Watts For 17 Bucks?

But even today, the no-name product market is showing the way. Dealers in our comparative shopping segment tgstores are already offering power supplies for as little as 17 bucks. For that you get a solid 300 watts, which is enough for most PC systems and mandatory warranty provisions.

And Kev prolly is still wondering what fried his TP II :p !
