    Be good if you can get your hands on one and give it a review.

    Wonder if this would be a viable - but not necessarily financially - replacement for my OCZ ZT 750w unit (no it isn't dead, but custom cables might be easier to come by)...?

    Does your case have a PSU mount where the space-where-the-fan-would-go can face up and out of the case? If so, you can put in a fanless PSU no problem. If the fan-hole can only face down, then a fanless PSU is not a good choice.

    The case design is intake through the floor, rear exhaust... so in the latter category. :(

    I had one of their previous fanless PSU. Love it, but I think their hybdrid design is the better options. I have read, but not confirmed, that Seasonic under rated the fansless PSUn order to ensure their reliability under full load, i.e. a supply rated to 400W fanless could push more power with active cooling (I don't recall how much more). The issue is that most computer use cases don't draw max power for extended periods of time, thus the hybrid design allows for hardware that is not oversized (cheaper) and will actively cool only when required.

    I'd look at Seasonic's Focus Plus series, offers the hybrid fan control, including full off. As for cables I don't know about custom jobs but Seasonic sells extras and replacements through a partner site: https://www.btosinte.com/Cables-for-PS2-power-supply_c7.htm

    Edit:
    While double checking the URL worked, I noticed that BTOS Integration does do custom lengths and connector counts.

    ^^This^^ Unless you're going for a fully passive under load system the hybrids are a better option.

    By custom cables, I meant for my OCZ unit... dunno how/why no-one offers them, but...

    In-production units will be more favourable, but I dunno what's special about OCZ units that means custom cables/kits aren't available.

    Custom PSU cables are very much a niche product, no point offering them for anything but the most popular PSUs.

    There are people who will do custom cables for PSUs.
    Pexon pcs should be able to do whatever you'd like I believe.

    What he said. My NH-D15 will always spin a little, so will the fans on my graphics card. Even though I can get my system to be almost silent, the power draw is just to high to go passive. I think that's true for most halfway gaming-focussed builds.

    If you use high quality fans and run them at low rpm you can easily sleep right next to them anyway.

    fanless is nice, but will it be worth it to use in a gaming pc?

    most of the time with my Prime titanium the fan are not moving att all, so it could be a nice idea, seasonic knows hot to do good psu, my question is, is it Worth it? i mean the fan is really quiet, so i can trade a little bit of noise for more longevity all day

    you got the point

    With the right components yes, I have a Seasonic 520W fanless and paired with a low noise GPU like the 5600XT or the 1660s youcan build. a pretty nice living room gaming machine, also as a home theater

    High end gaming machine probably no, but there are people and companies attempting to build passively cooled high end systems who'd like a fanless PSU. Other applications such and a office, HTPC, etc are better suited for fanless PSUs and it will make a difference. I acknowledge that for office and HTPC one is unlikely to be using a high end 700W Seasonic PSU.

    A high quality fan is low noise indeed but it is not 100% silent. Having built a computer with no moving parts, there is a noticeable deference between very silent and zero noise. Interestingly I did not put my 400W fanless PSU in to my HTPC, but my main rig.

    it is probably a little more "niche" market for particular applications, you are right :)

    yes but considering power efficency... the power supply dissipates at least 50-60 watts... it's not a proper joke to do this...

    Seriously?? :O

    absolutely, the seasonic Platform is very efficient, and the heat produced is well dissipated by the internal heatsinks

    how is it healthy for a supply power to work at higher temperatures... well this is a different story
