    be quiet! was -the- go to brand for silent power supplies in Germany, so the name is more venerable than silly ;). Did have three of their PSUs die on me, which is around 50% of the units I bought, but those that die early get next-day replacement, and after three years of 24/7 use, many power supplies will eventually crack.
    Still, going with Seasonic and Enermax lately, and these models will probably be too late for my next build.

    Well...a dead PSU is pretty darn quiet if you ask me! Reply

    None of the PSUs I have owned have died in less than 3 years. Or ever.

    Take it as you will.

    I've had power supplies from cheap cases die - on the other hand, some of the power supplies that came with cheap cases worked like a charm for a really long time, more than 5 years Reply

    Yeah, it's only 550w, but it can "OC" to 650w and still retain 80 Gold spec, and its fan doesn't spin up until it absolutely has to. Great PSU, albeit kinda costy. Johnny Guru recommended! Reply

    Would somebody suggest a reason or two that one might prefer a single +12V rail over multiple? Both are seen, but I never understood why one would be better or worse. Reply

    it's probably easier to balance (and adjust for vdroop etc) multiple rails, when using multiple consumers, while a single rail is convenient if you have high power single end points.

    But how big that difference is, I'm not sure anyone can tell you except those that won't tell you because they sell it as a vague feature to have...

    It's arguably 'better' when overclocking to have a single rail because with multiple rails you run the risk of reaching the limit of a single rail by overvolting a high powered cpu and/or gpus. Reply

    With a well designed multi rail unit this won't happen, unless you've chosen one that isn't powerful enough for your build to begin with.

    Well designed & build single rail = well designed and built multi rail.

    I'm as puzzled as you are. Single rail is *always* more convenient since you don't have to worry about overloading a certain rail.

    Keep in mind that all psu designs are single rail internally. The rail is then split into many as they are passed through independent wattage limiters. So if it weren't for the limiters, you could have drawn as many power as the total psu rating from a single wire.

    Sure it's more convenient. But single rail means you lose proper OCP. That can be an important consideration using high wattage psus. Reply

    I'm quite digging the grill design. Besides being very unique, it is also kind of industrial looking.

    There are already 80Plus Platinum PSUs on the market from SuperFlower (rebranded by Kingwin) and plenty of other companies are readying their Platinum and Gold units.

    Regarding the single rail switch, why won't this issue just die already. For 99.99999% of computers, how many +12v "rails" a power supply has SHOULD NOT MATTER A SINGLE BIT.
