    Default HEC Cougar 1kw power supply....fails testing!

    I'd been hearing about how great and high quality the new HEC Cougar power supplies are and how we in the U.S. are being deprived of such a great series of power supplies. So, I went looking for some testing of them, which isn't much.....but I found one that looked like it was decently done.

    I really don't know the quality of power supply testing at Overclock3d, but they do progressive load testing and use an oscilloscope for tracing ripple/noise generation so it can't be all bad.

    Given that, they tested the HEC Cougar 1kw power supply about 2 weeks ago and during load testing, came up with this:

    And now we hit the major snag. The ripple output across all rails on the Cougar 1000CM was quite frankly shocking! Actually scratch that...I don't think there is a word which can describe how appalling 144mV of ripple on the +12v rail is during Test 1! This is already outside of ATX specification which states that ripple should be no higher than 50mV on the +3.3v/+5v rails and 120mV on the +12v rails, and we havent even applied any significant load yet! Similary the +3.3v and +5v rails are also cringe-worthy topping out at 118mV and 106mV respectively.

    Fast forwarding to Test 4 and as you'd expect, things only get worse. 194mV of ripple on the +3.3v rail, 192mV on the +5v rail and 212mV on the +12v rail. It's almost like somebody forgot to solder in the capacitors! At this point we actually uplugged the Cougar from the testing equipment and tried a different PSU in there to make sure that there wasn't an issue with our load tester. There wasn't.


    Full article found here: http://www.overclock3d.net/reviews.p..._modular_psu/1



    Man, so what happened to the great ps that is HEC? Just reverting back to their cheaper-than-cheap roots? It certainly isn't up to the quality of a Corsair, or Seasonic, or CWT, or Antec, or Delta, or Enermax, or most any decent brand sold here in the U.S. Maybe the above testing results are why it's kept in Europe.

    But at least it had a nice fan.....labeled HEC, naturally, but sourced from Young Lin.

    I like burebista's picture. What I did when back when I ran that 750W HEC unit. Dropped it right there and then.

    Its not all bad though, some pretty good efficiency numbers up there.

    Yeah, we know...

    But its not the 'real' cougar, there's already a better equipped version out wich has solid caps on the VRM for example....

    Here's a review (translated) of the 700W Cougar, I dunno whether it's a fake unit or real or whatnot though. Reasonably ok voltage regulation, good efficiency but kinda high on ripple.

    No, that's a real Cougar CM.
    I own the same 700W Unit (I know it's a little oversized for my system)...

    Haha, yeah. Apparently Google Translate decided to translate "centimeter" into "inches" for some reason. But the article in Norwegian has the correct fan size. ;P

    on the subject of Cougars, is this unit made by Enermax?

    it has 648w on the 12v rails, 80+ Bronze rating and the cable sleeves just look Enermaxesque...
