How come the thermaltake PSUs say no under "80 Plus" but they all have 85% efficiency stated?

I don't know maybe I'm too noob but that confuses me.

I think its because they didn't apply for the certification...

Take the efficiency with a pitch of salt because actual efficiency might not be what is stated on the box. Anyway I have also corrected some errors with the thermaltake psu on the 12V max wattage.

Another point to take note is SLI-Ready does not necessary mean SLI certified.

80 Plus is not only the efficiency. It is a very comprehensive test. Not only is it money. But it is a true test.

IT IS TRUE that some manufacturer will not submit ONLY because of finance issue.

BUT it is also true that some manufacturer submit cannot pass, or dare not submit because they KNOW they are cheating and they will fail.

There is a LOT of cheating going on in the PSU world. I intend at least do my bit to sort it all out here. Sexposures are very very welcome.

I hope I am not misleading anyone with that chart.

no the chart shows efficiency, not 80Plus certification. It's the best you and I can do bro. And it really makes it more difficult to cheat. Kudos to you.

Some reasons that can be speculated

1) Product fail spec ( 85% might be able to attain at only a certain load but not all loads or some other criteria not met )
2) Didn't want to incur additional cost to the product

Most of the time, it would be because the PSU cannot meet the standards of 80PLUS. Its a simple standard - greater than 80% efficiency at 20/50/100% load.

That would imply that the PSU MUST live up to its rated wattage. A 500w PSU must be able to sustain 500w load to achieve 80PLUS cetification.

So you might ask.. why doesn't for example, a Corsair HX520/620 have 80PLUS certification? Corsair's got plenty in its coffers and so does the OEM Seasonic.
Reason: it fails 80PLUS at 20% load.

So to put it simply, thermaltake specifing UP TO 85% might mean that its efficiency could be 75% at 20% load but 85% at 60% load.

enermax for example is pretty truthful about their specs. "about 80% efficiency from 30% to 100% load.". online independent reviews puts the efficiency around 78-80%.

There's a lot of misleading going on in PSU marketing. eg. typically >70% might mean greater than 70% at typical 50% load, but might fall below that at other loads. up to 80% might mean 68% at 20% load, 73% at 50% and 80% at 75% load etc. 80PLUS simply certifies 80% efficiency at 20/50/100% loads.

ER: bro, you might want to change your efficiency columm to include greater than, lesser than, up to etc certain efficiencies.

It's a simple standard, yes. BUT I have been told that the testing procedure is not simple and the parameters of testing are very strict.

A starting point I was given, for example, was the adoption of the generalized internal PSU testing protocol : http://www.efficientpowersupplies.or...tocol_R6.1.pdf as one of the protocols used. In fact an entire suite of testing methods are specified here: http://www.efficientpowersupplies.org/methods.asp and some of the parameters are difficult to meet.

If one cannot meet the testing parameters you can't achieve 80Plus. Therein lies the difficulty.
