Hot Test Results (~45°C Ambient Temperature)
In our elevated ambient temperature test, the Be quiet! Straight Power 12 750W PSU experiences a notable dip in efficiency, dropping to an average of 90.6% under a 115 VAC input and 92% with a 230 VAC input. Despite this marked decrease from its optimal performance levels, the PSU remarkably exhibits no thermal stress indicators, even when operating at its maximum capacity.
The Be quiet! Straight Power 12 750W PSU's fan operates with a controlled strategy, ramping up as needed to manage thermal output. Despite the very high ambient temperature, the speed of the fan is fairly low when the unit is lightly loaded, maintaining comfortable noise figures. This is achieved via the PSU's large heatsinks and its efficiency levels that surpass the norm for its category, leading to superior thermal management. Despite the fan's increased speed under heavy loads, the noise remains manageable with a constant load of up to 600 Watts, striking a fine balance between cooling effectiveness and noise control across most of its operating spectrum. While the fan becomes more audible with heavier loads, the internal temperatures remain remarkably low, evidencing the unit's adept balance between thermal regulation and acoustic performance.
As the fan accelerates under the thermal control system's command in the Be quiet! Straight Power 12 750W PSU, the unit adeptly regulates its internal temperatures, keeping them commendably low for its category. Still, the low internal temperatures would suggest that the designer had more headroom to lean towards low-noise operation at the expense of some thermal performance. In situations where the load exceeds 90%, the thermal control circuitry prompts the fan to reach its highest speeds, while the internal temperatures are far from the OTP trigger point. This is adeptly calculated for a top-tier performance PSU, where the designer wants to make sure that there will be no thermal stress reducing the performance of the active components while the PSU is heavily loaded, especially with a design that is likely to have to combat heavy power excursions from a gaming GPU.

Would his code be of the well written, or poorly written variety? ReplyGeoffreyA - Wednesday, April 10, 2024 - link
I agree: it's no easy business producing videos, and is an investment in money and time. ReplyRyan Smith - Tuesday, April 9, 2024 - link
If y'all could save the doomsaying for the forums, I would appreciate it. I like to give you guys a great deal of leeway in this "straight out of 2001" comment section, but there's something to be said for not scaring off the readers.On a side note, my door is always open if you want to talk shop.

Apologies, Ryan.Except for when the indenting stops at a certain depth, I think the "2001" comment system is excellent. The so-called modern ones are a mess. Reply

'The so-called modern ones are a mess.'Especially Arstechnica, which has reduced comments into an inane popularity contest with its voting + post hiding game. For a site that likes to use Latin, the staff clearly are unaware of the argumentum ad populum fallacy. Either that, or they prefer their comments section to be inane. Reply

While I rarely look at Ars, comment systems today are clumsy, and the liking-disliking mechanism is a disease, probably first popularised by Facebook. From a clumsiness point of view, look at YouTube; I would have expected better design from Google. ReplyOxford Guy - Thursday, April 11, 2024 - link
Slashdot had that like/dislike + hiding nonsense a very long time ago. Its comment system suffered accordingly. ReplyGeoffreyA - Friday, April 12, 2024 - link
I didn't know that. Well, I suppose most concepts have their inception in one place and popularity in another. ReplyPeachNCream - Tuesday, April 9, 2024 - link
Aw shucks, that's my fault. I started it and as longtime readers of AT, we want this site to be successful so I think we often get carried away while we wait in fear of things to come. I'm sure I can speak for all of us when I say we hope that, no matter what the future holds, everyone ends up on their feet doing something they can enjoy that leverages their skills.As for indenting, if the current comment system has enough indent levels to stop acknowledging them, its gotten too deep anyway. I personally couldn't care less if it can't cope with that or requires scrolling. Reply

Blaming the comments for the drop off in traffic isn't going to help you or the site. Readers are not "scared" by criticism, they're leaving because you guys barely put out content these days, and what content does get made isnt to any higher standard than a myriad of other sites. Just compare Anandtech 10 years ago to today. Mentioning the GPU issue always seems to elicit negative reactions from staff, likely because there's a lot of truth to it.On a side note, saying your door is always open if you want to "talk shop" in the same breath as you slamming the door on conversation because you think it looks bad is REALLY tone deaf.
