    Default Silver saints! Enermax 850W/1050W Revolution series

    Again Enermax showed their 82+ series to the public in Computex08 Taipei...
    http://www.expreview.com/computex08/...9098d9108.html

    but now we see a brand-new high-end series, Revolution, successors to the Galaxy series, hitting the high-power efficiency championship.

    http://www.80plus.org/manu/psu/psu_d...x?id=28&type=2

    Both units are just pre-production samples. Both have shown exciting efficiency numbers(88.6% typical). Judging from the data they have four 12V "rails".

    So let's welcome two new silver saints. This year is the "year of 80+ Silver".

    plus: According to Hexus.net, Enermax had a close-door show of this Revolution procotype in Computex 08. http://www.hexus.net/content/item.php?item=13634
    I think this is the most interesting part of PSU section in this Computex08. Also we have AcBel showing its 80+ silver "R88 Power" series.
    Now that two famous manufacturers have introduced their 80+ silver product lines, both in high-end range, the Galaxy War of Silver has begun.

    80+ is nice but in my book is a worthless metric to judge power supplies by. It will be interesting to see if these current modulo units have lower failure rates than the liberty units or not. Too many reports of them blowing up for comfort.
    Software readings are crap.

    I don't see many Enermax here in China so I can't see how the failure rate is. What caps are Liberty using? What's the symptom of the bad units? Does "blowing up" mean blowing up caps or blowing up transistors/resistors?

    Transistors and diode-packs. Search this forum and you will find many complaints.

    Unfortunately, I have very little confidence in Enermax these days considering the issues many people have had with their recent units. Without a doubt it is great to see near 90% efficiency but that means very little to me if the PSU is going to self destruct after a year or two.

    Agreed. Going through Computex this year, I'm finding 80 Plus is now "old hat". I'm seeing 80 Plus from Huntkey, Wintech... companies not known for best quality. Even out-of-nowhere start ups like Dominion are pushing 85+ efficiency on 1000W+ units.

    Efficiency is no gauge of quality for sure.

    Yeah - everybody and their dog is now using the double forward converter design. It was inevitable more units would pass 80+ as a result.

    Double forward is by all appearances far better than half-bridge that Huntkey is still sticking to even in their 600W units. Better efficiency, less heat, and you have much better switching transistors as your choice. Everybody is using a double forward on their unit and this is not a bad news.
    The problem is if they're willing to build a quality unit, or just an efficient unit.
    After all, one of the most important reason that many choose "good" PSUs is that, they're expected to last longer, but what if they don't?

    Anyway I don't believe a company like HiPro or AcBel would build a product series that easily burn itself after 1 or 2 years. --But for small or less renowned providers like Enermax/Huntkey/Wintech, I'm not sure.

    Some guy included Enermax in the "first-class PSU provider" list (while AcBel/Enhance/Delta are rated "second-class"), that's... awesome indeed.

    Enermax has a pretty good reputation in the west even with some of the primary side failures. Hipro/AcBel are almost completely unheard of's

    Who's that Dominion?
