    Default HardOCP's First Review: BFG 1000W

    http://enthusiast.hardocp.com/articl...50aHVzaWFzdA==

    That is one great reivew right there. Just like the PCPer review, it does not output 1000W but this time it does live up to its 80+ certification.

    One line that did concern me though:

    This bouncing does occur with a number of power supplies so it is not unique to this Topower/BFG PSU but a top tier PSU should be regulating its output better than this.
    As far as I am concerned, Topower is not a top-tier PSU manufacturer.

    Yeah I was pretty skeptical myself while watching the traces....but they checked accross two units. Unfortunately before I was able to really try and force the issue the units died.

    Are you sure your o-scope is working?
    I find it odd that Lee's review found excessive ripple on the +3.3 and +5V rails at 600W and 800W but your review unit's ripple was quiet as a tomb. Can there be THAT much difference between units?

    It was when I set it up and tested everything before the BFG review. I was using a Betsec PSU as a base line and it showed a much dirtier profile comparitively (until it died) unfortunately I wasn't recording anything because I was just testing. It is still within the realm of possibility that something happened to it....and i have another unit set for this week. If I see something similiar that would probably answer the question.

    Hate to say it, but your Oscope is definitely all wrong. Ripple's not that low on that PSU.

    3.3V is a straight line. That's impossible. You're should at least see some movement, even if it's .5mV, just from ambient RF.

    Whenever I'm in doubt, I change the V/div on the Oscope from .05V to .01V and look for a change. I'll also turn the dial back and forth to see if I get a "jump" in my waveform.

    I did try adjusting it, swapped BNC cable, etc and the only thing that changed was on the 12v with the BFG. I couldn't get the 3.3v/5v to do anything. I have another PSU that should be there today and I am going to give it a shot and see what is going on.

    Jonny is right as usual....I don't see ANY play on the +3.3V readout. Is it possible that something is interfering with the signal?

    Hopefull the review will be edited accordingly once the problem is found.

    I don't know what kind of intereference it would take to completely cancel out a waveform.
