    Maybe Kingwin will pull the newer low power SuperFlower designs in too. You could always ask them if they will.
    nice review

    nice price too... minimum load of 300w doesn't show low load efficiency...

    as more efficient computers are now...i would have liked a low load(100watt-ish) test even with a 1kw unit...

    If I went the x12-II range I'd much prefer the modular M12-II, as it's going into a crammed (albeit large) HTPC case.
    for low load the x650 and x750 doesn't do high efficiency...i remember fm or pwm modulation was applied.

    if you look at slpreview...at low load...the x650 didn't fare well...

    not sure what you want to achieve..but seems you want ultra low power pull from the wall even at (90w or less) idle or sleep mode for your pc...

    if i were you id get that seasonic s12/m12 520...seems very good. but if you have a power hungry videocard the x650/x750 is a better choice if you idle around 120w or more

    i have a laptop that idles at less than 20w but videocard sucks...i can't watch high def on it...

    Thanks for responding, I outline -basically- what I'm trying to achieve here.
    It's more-or-less in line with what the OP is wanting....

    Hmm this seems to contradict what others have said: 1, 2.

    Everything I'm hearing indicates that if I don't want to compromise on efficiency & DC-conversion (ripple/stability etc)
    Then I'll have to settle for something substantially above 500w?

    Yes and no.

    Efficiency is usually lower at less than 10-20% (depending on the PSU) and ripple is usually higher the closer you get to full load.

    But 99% of the PSU's out there have ripple within spec eve at 100% load, so the latter should be a non-issue.

    what exactly is your cpu/mob and videocard? those two essential loads can determine which psu you'll need...

    and as for dc output...don't worry about em ripples..most psus like what jguru says is within specs ..

    Whoopie, ~25% is the bottom end we do, always has been. I could test at 1W with the SM-8800 or OW could with the SM-268 if he wanted but it is not worth the time.

    as more efficient computers are now...i would have liked a low load(100watt-ish) test even with a 1kw unit...
    No, it's [H]ardOCP our target audience does not run their computer on a pico, {s}oftOCP is that way ---------->

    apologies if some of this has been answered, I looked but couldn't see.

Course they're also coming out with 560/660/760 watt x-series models. I assume the 560w would be the most logical pick for anyone assuming it's cheaper than the 400w fanless.
    So is this their next-gen DC convert tech which is better than what's used in their current x650?
    When are these new 400/460/560/660/760 X-series models coming out?

    I don't know if it'll be just as efficient or stable; as some platforms do not work as well going lower watt (just their design.)
    So we'll have to wait for some reviews. But I doubt we'll see units going out of spec or producing bad results.
    But I do see some issues with a unit like the X-400 being fanless
    So just to clarify,
    This new range you're talking about will basically supplant the X-650 & the like that's out now?
    i.e. they're a next-gen design?

    Well I've not seen any reviews or many internal shots; but for the most part they look the same.

    I wouldn't call them next gen; but more of an expansion on current gen tech.

    Though; yes the X-650 & X-750 will be replaced

    I believe someone mentioned there's virtually no difference between the 650 and 660 models and same applicable to the 750/760. Makes sense, I don't see any point in a brand new psu version yet.

    That was Jonny I do believe.

    But yeah, I feel they're giving them new names just for the sake of selling units & hype.
