Cold Test Results (~25°C Ambient Temperature)

For the testing of PSUs, we are using high precision electronic loads with a maximum power draw of 2700 Watts, a Rigol DS5042M 40 MHz oscilloscope, an Extech 380803 power analyzer, two high precision UNI-T UT-325 digital thermometers, an Extech HD600 SPL meter, a self-designed hotbox and various other bits and parts. For a thorough explanation of our testing methodology and more details on our equipment, please refer to our How We Test PSUs - 2014 Pipeline post.

The Be quiet! Straight Power 12 750W meets and surpasses the 80Plus Platinum certification standards, showcasing exceptional electrical conversion efficiency. With a 115 VAC input, this unit delivers an average nominal load range efficiency (covering 20% to 100% of its capacity) of 91.9%, and an impressive 93.2% efficiency when powered by a 230 VAC source. Like most manufacturers, be quiet! received the certification rating with an input voltage of 115 VAC, where the requirements are lower – however, the 750W version of the Straight Power 12 also meets the 80Plus Platinum certification requirements with an input voltage of 230 VAC.

The Be quiet! Straight Power 12 750W PSU doesn't feature a "hybrid" fan mode, which means its fan is active from the start. Thanks to its design, the fan operates at a very low speed even when the load reaches up to 50%, ensuring that the unit runs quietly under typical conditions. As the load increases, the fan's speed increment is modest, designed to keep noise levels down. Despite this conservative approach to fan speed, the thermal control circuitry manages to keep internal temperatures surprisingly low, even at full load. This indicates high energy conversion efficiency paired with a somewhat oversized cooling system, designed to be capable of achieving top performance at minimal noise levels.

    Would his code be of the well written, or poorly written variety?

    I agree: it's no easy business producing videos, and is an investment in money and time.

    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.

    '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.

    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.

    Slashdot had that like/dislike + hiding nonsense a very long time ago. Its comment system suffered accordingly.
  • GeoffreyA - 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.

    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.

    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.
