Perfect! Thanks! Along with all your other pointers, this gives me a much better idea of what direction to head in. I suspect I'm going down the Corsair route and replacing if the technology leaps with DDR5. Hope you have a lovely weekend buddy.

Sorry - I missed this comment before. I read it was a mix of frequency and pulse width on kitguru but that was for the 550 so not sure if it's the same on the 850? Incidently, I found the link about the Straight Power being load driven which I put in my last comment but again, not sure of its vadality? It looks like no one knows the pros & cons of temp vs load but aside from that, I just wish there was a way to find out if any fan is going to be more beneficial for my (VR video friendly) Threadripper build? You're probably too busy but if you happen to read this comment and my last one, I would be eternally grateful for any of your wisdom as have been pulling my hair out over this for days. Thank you so much in advance if you can! EDIT: forgot kitguru link

Legend - appreciated. Must have got it mixed up with one of those then. Ha- sorry. Guessing it doesn't matter then? Just out of interest and as I'm concious I don't want to take up much more of your time, assuming 850W is enough for my build, could you possibily help me with your 1st and 2nd preference between: BeQuiet Straight Power 11, Bitfenix Whisper, Corsair RMi, Enermax Revolution D.F, etc. Don't worry if you are too busy for any reasoning - any help is appreciated! EDIT: not sure if it helps but it was the 750W version of the Straight Power 11 that I read was load driven but that was on Anandroid so not sure they know their stuff as seen here. In your experience, would you think they likely got it wrong?

Really appreciate your respponse. Ahh crumbs! I'm so silly sometimes - must have got them mixed up as my brain is so fried after so many days PSU research. My appologies. I was orginally looking at the BeQuiet Dark Power Pro 11 850 which I believe must be the one that's load controlled? Can't for the life of me work out if that's a benifit for the things in the OP and for keeping the room as cool as possible? I guess load vs temp might not be much of a contributing factor but can't work out the remaining pros/cons - would certainly welcome any of your wisdom to nudge me one way, or any better similarly priced althernatives for a Threadripper work-only, occasional VR video build? Will be a huge relief to tick this one off so huge thanks for anything really. Warmest regards.

Thankyou greatly in advance if you can spare a few seconds to help me out with hopefully a simple one. I'm prevalent in providing support in other forums but new here so nice to see there's lots of lovely and helpful people here. (If I've missed any rules, please do not hesitate to let me know.) I'm building a UK sourced 3rd Gen Threadripper (although starting with TR2/X399 for the next year or so.) No gaming, single VR friendly RTX 2080 GPU, 128GB mem, 1TB Nvme, etc. (undecided between 850W vs 1000W because once adjusted, the build is possibly showing 780+ draw.) England isn't the hottest place on earth and I much prefer the cold so probably have an ambient temperature of 0C-10C(32F-50F) 70% of the year, 10C-20C(50F-68F) 20% of the year and 20C-30C(68F-86F) for the remaining 10%. Have several on my comparison sheet such as: Antec High HCP-1000 Platinum, BeQuiet Dark Power Pro 11, BeQuiet Straight Power 11, Cooler Master V850 Platinum, Bitfenix Whisper , etc. It looks like my main contenders are the Whisper which is controlled by temperature whereas the Straight Power 11 is controlled by load. Despite much research, I've been unable to qualify the pros & cons of either so would very much appreciate your thoughts on 'Load' controlled PSU vs temperature controlled PSU (even better if supported with sources or science.) Some concerns are noise and energy efficiency, i.e. - if the fan spins under load but the temperature is fine then that's unessicary noise/energy. On the flip side, If it's 20C+(68F+) in the room, it might need to spin but the load isn't enough, resulting in degradation. Any other concerns I should take into account between those two or others? Whispers are popular but I would say Bitfenix forte were mainly cases and they appear not to have as good of a track record. BeQuiet have lovely fans and are transitioning more into PSU's going forward but not sure if their 'load' controlled fan is more or less beneficial than temperature controlled. Huge thanks in advance - deeply appreciated! EDIT: spellings.
