这么多的电源品牌，几乎对于80plus都是用骗的。
敢保证出货真的完全100％通过当初申请的80plus等级的品牌近乎为零。
最近刚好有一个案例可以看，不知道还可以看到多久。
最近一大品牌的850/750w的新产品，在 ...

这里有一条楼主可能会比较感兴趣的消息。

简单说，海盗船认为他们的HX750W/HX850W不能保证全部达到80Plus金牌的效率，而只是接近金牌，因此将80Plus金牌认证改为银牌认证，在产品上使用80Plus银牌Logo——这也是他们设计HX750W/HX850W之初的定位，即最好的80Plus银牌电源。海盗船还在与Ecos协商在80Plus官方目录中将HX750W/HX850W改划入银牌类别。
能开放弃金牌回归银牌这个先例，海盗船还是显示了勇气和责任的。
[HEXUS] Why did your PSU get wrongly certified?
[Jim] I'm not sure I would characterize it as "wrongly" certified. According to the 80Plus organization, the unit we sent in for certification is an 80Plus Gold PSU. We have every legal right to claim 80Plus Gold. However, the unit we sent in to them showed lower results on our test equipment. It was very close to reaching Gold but didn't quite make it on the 100% load test.
We have elected to certify the PSU as 80Plus Silver because that is exactly what we designed it to be: the very best 80Plus Silver PSU on the market. The fact that a single unit passed 80Plus Gold doesn't mean we can guarantee that every customer would get a PSU that met that standard.
There are so many factors that go into the efficiency rating: production variances, component variances, differences in test rigs, temperature differences on the tested units, and so on. Across the bell curve of units we product, some will be at the very high end of the efficiency spectrum, some right on our targets, and some at the lower end. The middle of that distribution curve is what the majority of our customers will get, in terms of the efficiency of the PSU they buy. We know that we can guarantee 80Plus Silver across the full curve because that's exactly what we designed the PSU to deliver.
The fact that we're so close to 80Plus Gold is a testament to the quality of the design. The fact that we won't certify as 80Plus Gold is simply that we can't guarantee every unit produced would have the favourable variance that would cross that threshold from Gold to Silver. Keep in mind that we cleared 80Plus Gold by less than half a percent!
Of course, in fairness, I'd like to point out that no one has passed 80Plus Gold with much more. In fact, all of the 80Plus Gold certified supplies have passed with less than 1% to spare on one or more measures and one is "certified" with just 0.01% (one one-hundredths of one percent!) to spare.
[HEXUS] What obstacles are you finding to getting it re-classified?
[Jim] I don't think it is fair to say there are obstacles. We've asked the 80Plus group to allow us to use the 80Plus Silver logo and they've granted us permission to do that (though I have to say, I think they think we're crazy!). We'd like to have it moved into the 80Plus Silver category as well, and will work with them to get that done. |
