Power Supply Roundup: Part II

Tagan SuperRock TG680-U33II

The Tagan SuperRock TG680-U33II has a maximum performance of 680 watts. Conspicuous on this model is the LED on the rear of the power supply, which shows the operating status: green means that the unit is operating, while orange tells you that it is in standby mode. The power supply is fitted with a 120 mm fan, which is located on the underside and regulated automatically.

    Nice review, I was hoping to see the Antec NeoPower series as well :(

    I use the Enermax Modu82+ 625W version (same design) and I can attest the 12v rails are rock solid, they just don't sag or dip under any load.

    The fan is interesting, I am used to the variable control knob but I do not miss it as the fan is silent under all but the heaviest sustained load and then it is audible, but not loud. It is a 120MM fan (quieter) but it is clear (louder). The fans' RPM monitoring lead is a must for my system board monitoring program as I could adjust other fans and settings based on the PSU fan RPM if I wanted, but as I run a near silent system, I have no need.

    I wish it was $50 cheaper, but you get your money's worth, no mistaking that.

    Hi,
    I sill miss some bits.
    I would like to see how overcurrent and overheat protection works, whether mains spikes can damage the power supply.
    Whether joining +5V with +12V rail (as may happen when e.g. CDROM fails) will burn the other components.
    And noise/heat level.

    Yep just about as informative as the first part, IE. not very.
    Unless you put the thing under load and oscilloscope the outputs for ripple and open it up to see the type of parts used and the construction quality. reviews of this type are next to meaningless.

    Love my 22 month old Antec NeoPower HE 550.

    "But there is no 82Plus standard."

    Clearly these folks don't know about the different colors of the 80+
    program. The enermax is rated at the bronze level which must be 82% efficient. There is also the silver and gold level rating.

    google is your friend.

    "For what it’s worth, that’s good enough to qualify the supply for the 80Plus Bronze certification, if Enermax pursued it."

    Not only did enermax pursue it, but if you go to 80plus.org, you will
    see that they are already certified at the bronze level. (80plus.org is
    down right now, or I would provide a url showing it.)

    If you go to enermax's site, http://www.enermaxusa.com/catalog/index.php?cPath=21_56
    they have a big honking picture of the 80+ bronze certificate and the 6 power supplies it applies to. I fear tomshardware has not done their homework.

    Other than owning a 5 year old Enermax, I have nothing to do with the
    company. I have 5 antec earthwatts powersupplies, and a seasonic power supply in my 80+ collection.

    Listing "Confusing “82+” specification in the product name" as a negative, clearly shows where the confusion lies, and it isn't with enermax.

    The 80+ standard is several years old. The newer colored standards of bronze, silver, and gold are newer, but that is the wonder of technology.
    For a technology web site, keeping up with newer things such as standards is necessary.
