367409 2005-06-29 05:59:00 I'll wait until some proper reviews are around.

You may have to wait a long long time PCT.

The expertise and equipment needed to test a PSU in any fashion relevant to its end use are unlikely to be found in any computer reviewer's box of tricks, and in fact a good thrash in a highly stressed system under marginal overload conditions is an excellent substitute and very relevant to a typical end user.

Very few people would be able to make any sense whatsoever out of a professional test report either, they'd just choose the bits that sounded vaguely familiar and make a value judgement based on the limit state of their knowledge.

Of course that's just my opinion, and I could be wrong, but many years of experience working with and on switchmode power supplies beats a guess in the dark. :D

367410 2005-06-29 22:34:00 How long have you owned them? If they've been going 3 years I'll agree with you.

The 4 hundy has been going for just over 2 years, the 5 hundy is just on a year old. They have been through power cuts etc, no problems with performance.

367411 2005-06-30 01:59:00 Well thats a good test - 2 years. As for Billy Ts comments, a good review not an electricians technical report.
There are such things which involve a bit more than what Tweaktown did.

Read them both PCT and they are a load of amateur bollocks . Full of misinformation (some of it utterly laughable) and zero examples of credible PSU testing . No information about controlled power input conditions, no details of testing procedures, no description of test equipment used to measure outcomes, not even a little box on the side labelled "information for technical junkies" with helpful information; and above all, nothing to establish the credibility of the writers or their credentials to support their findings .

Point me at a review that shows hold-up time under transient outages (maintains full output from "stored power" to prevents your PC rebooting) or output stability under transient loads as I mentioned previously and perhaps I'll be convinced .

Until then, I will maintain that good thrash in a highly stressed system under marginal overload conditions is a better indicator of real world performance than any of the "no actual examples" hype on those two sites, or any of their associated links that I followed .

Some accurate information, lots of populist techno-babble, leading to recommendations for personal favourites .

7/10 for effort, 5/10 for actual real-world value .

Can you tell me which parts are misinformation & laughable? Just so I can recognise it in the future. :)

If you can't see the technical inaccuracies or other weaknesses E|im, I don't have the time, the will, or the desire to educate you . I am not saying that the power supplies mentioned are bad, just that the so called "technical reviews" are seriously flawed and have no more real-world validity than an empirical test in a potentially stressed system .

My comments are based on more 40 years of professional experience in electronics, and a significant amount of experience associated with SMPS failure analysis, testing and repair . You can take my word for it, or believe what you read in those web pages . The choice is yours, it's a free world and quite frankly, I don't give a damn either way .

Cheers

367415 2005-06-30 23:51:00 Come on Billy we know your credentials and that your a clever cookie, I for one would be interested in what elements of the review aren't up to sctrach, I like many others come here to learn as well.

A couple of paragraphs should cover it surely?

367416 2005-06-30 23:57:00 Yes, elighten us. First you say Very few people would be able to make any sense whatsoever out of a professional test report then you rubbish the ones around. So let us know what we need to be looking at. pctek (84)

I don't like that elitist attitude. :groan:

I'm just asking nicely to point out a few things that are wrong with the Silent PC Review site and what they're saying? Also the things that are completely wrong. A few sentences really. In the words you spent telling us how you were too awesome to explain it to us, you could have just told us what was wrong with the pages.
