We do not buy standard units off the shelf. We make significant modifications to the layouts and specifications, including fans, electrical components, etc.
I'm not going to address the other things because they stand on their own. Some of these things I've been saying over the years.
As for these two cherry-picked items,
1. I'm pretty sure I see a reference to Corsair HX750 / HX850 vs. Thermaltake Toughpower XT 575W / 675W / 775W / 875W, though maybe I'm forgetting something else too. To be honest, this is an example I think of myself sometimes, how you souped up CWT DSG. Or is my timeline off? I thought the Corsair units were out before the Thermaltakes, or at least that's when reviews appeared (2009 vs. 2010). Or was it some CWT PUQ / PUQ-G units or even back to some of the PSH-based power supplies? Hm...
2. Along those lines, by "modifications to the layouts" I don't know of a way to interpret it other than significant PCB changes, changing the circuit and components or at least routing the wiring (well, PCB traces) differently or possibly just heatsink / physical components changes. I don't really recall significant PCB changes (by casual visual inspection, which is admittedly not at all a way to thoroughly investigate anything as complicated as these PCBs) in recent power supplies when compared to similar offerings from competitors, not that I'd think that whatever the OEM had in the first place necessarily needs a change—it probably doesn't. Am I just not looking that hard, do you mean something else, or perhaps are the substantial differences in say AX1200, AXi, or other more custom offerings that aren't on commonly used platforms? I can't say I recall seeing a different layout on say CX than what competitors offer, TX V2 than what competitors offer, AX than what competitors offer, etc. This is all differences in fans, fan modes, components choices, cabling, customer service, price, etc. aside.
I'm not saying I expect a difference; rather I'm curious to see what I've missed or if it's just a misunderstanding.
Now for a different and more important matter, what's with the obsession with hybrid fanless modes, anyway, to have them on so many of the product lines? I care more about acoustical noise than the vast majority of users, and I don't really see the point. Run a lot of these fans at low speeds and nobody's going to hear them anyway except maybe the guys that are in the market for completely fanless power supplies, and that doesn't really seem to be your target market. And with some forced airflow, you could give some of those capacitors baking near the heatsinks a bit of a better fighting chance, huh? Okay, maybe at low fan speeds you're not really making an incredible temp difference where it counts, but still.
And the more complicated the fan control needs to be, especially around the turn on/off area with the hysteresis control and all that, the more chances there are for problems, which is something you already saw on the earlier units rolled out with the feature, right? Especially on platforms that didn't already have this to begin with.
Do the users demand it? Is it a marketing checkbox kind of thing? Does it really help? I mean, it's probably not a big deal either way, but I'm not convinced you're on the right side of things, especially with the midrange units getting the feature. You're also certainly not the only ones doing it.
I guess it's cheaper to implement than upgrading the fan quality, caps and ICs and other components, getting bigger heatsinks, etc., and running slower fan speeds throughout the load range.Edited by mikeaj - 1/24/14 at 8:54pm
