"..a significant decrease in efficiency, with figures dropping to 87.9% under a 115 VAC input and 89.5% with a 230 VAC source, compared to 89% and 90.5%, respectively.."
1.1% and 1% is significant ? Doesn't that boil down to a difference of a few watts ?
When you're writing an article it can be difficult to think about things from an outside perspective. AT has noted via response to comments in the past that there isn't a review like one would find an editor performing before publication so they sometimes rely on readers pointing out things that could be improved and make edits after an article is out the door.
I can't recall many Anandtech articles that haven't had suggestions from readers in the past probably six or so years. It shows the effectiveness of crowdsourced post-publication review to improve article quality and has been helpful so I believe feedback like yours is always beneficial when there isn't a team of professional writers and editors available.
And, to be fair, even well-known news sites are in a hurry and cost-sensitive so I see actual paid professional articles with the rare error or typo that slips out before publication. One or two errors per article isn't too bad considering Future doesn't have the same hiring power as an established, well-known company.
1% absolute is significant when you're talking about energy losses. Even though this is only a Gold PSU (a couple steps down from ultra-efficient Titanium), that's still an effective increase in energy losses of 10%.
It's typical and expected for PSUs to lose efficiency in our hot box testing. We've had Gold PSUs fare better than this, though.
It does. However, that few Watts worth of difference merely due to the elevated temperature, from a technical point of view, is a major concern. The greater the difference, the more the active components are getting thermally stressed. Ideally, a great unit should have a very small difference in performance when the ambient temperature changes by ~20C, as long as the temperature remains under the unit's maximum rating.

I haven't tried their power supplies, but the case I'm using is DeepCool's Tesseract. No complaints, and the fans have worked well for five years.Tunnah - Tuesday, March 26, 2024 - link
