    Default Enermax Revolution Duo 700W Power Supply Review @HARDOCP

    Two is always better than one, right? Two fans in your new PSU is a win-win? That is the theory behind the Enermax Revolution Duo series of Power Supply Units. Enermax has a long history of producing PSUs ranging from good to excellent. Where will the new Duo fall in line today?

    [...]

    The Enermax Revolution Duo 700W is the latest in a very long line of power supplies that we have seen from Enermax proper. In that time, we have seen a number of innovative products. However, what we haven't seen from Enermax is a "retro" product; until today. Today, the Revolution Duo 700W represents the newest 700W product we have seen from Enermax but also the one that is using a design we have not seen in wide usage in a very long time. Obviously, by going back to a design style that people have moved away from, Enermax thinks there is something we are all missing. What is it though? Let's see what Enermax has to say about this unit and its product placement:

    With the increasing demand for computer cases featuring PSU-Tunnel design (aka PSU shroud), REVOLUTION DUO is equipped with DUOFlow™ design to provide active ventilation and make efficient airflow management. What’s more, the patented FMA technology allows users to instantly adjust the airflow via a turbo switch based on their system need.

    Finally!

    Hm...Teapo rated at only 85º?

    Results are OK.

    But again...i see no point on this unit. Enermax is wasting resources in a product line that wont sell, for various reasons, while they have NOTHING to really compete with DC-DC Bronze units under 60-70€ and are obliterated by the usual suspects, in every price range, in every efficiency range...in every aspect you can imagine besides that Twister Bearing fans.

    I used to have pity for them, but after i saw what BitFenix could do with Whisper M, i havent anymore.

    I hope they really improve their PSU offers with the new lines incoming.

    For a budget unit I don't mind...

    But the 330µF for a 700W unit I would mind...

    I'd like to see at least 470µF, if at all possible 560µF in a 700W PSU...

    Yeah, no way this unit meets ATX spec for HUT.

    And at what temp this PSU is rated? I didn't find anything in the review on this respect. Specs at Enermax's website also omits this.

    The market is full of "useless" PSUs. How many people do use system with CF/SLI, for example? However, most of the releases are on the 650/750 W or greater. Sub-400 W? Forget about it.

    BTW, I don't get their marketing about being the ideal PSU for cases with a PSU cover... Seems for me it's more interesting for cases with the PSU on the top.

    100mm? 80mm? I could see even 120mm for the big fan, but don't they have a patent for 140mm fans on PSU's?

    I guess it's Super Flower (that patent owner).

    Yes. Super Flower owns the patent on 140mm fans. That's why we see funky diameters like "138mm" on some fans.

    Other interesting patents: Seasonic's patent on a zero RPM fan on/off switch (Taiwan and China) and on putting the DC to DC on the modular interface. Gigabyte's patent on putting a USB port on a PSU (Taiwan only).

    Other things are patented, but nobody enforces them. For example: Topower invented and patented the 20+4. But everyone uses it.

    Really? I think the transient response is much more a concern on this PSU than ripple.
