DC Output Stability and Quality








The DC output regulation is excellent with this power supply. Both the 3.3V and 5V rails have a regulation little over 2%; even at maximum loads of over 1000W, they stay just 1% under the ideal output. The standby rail has a larger regulation of around 6%, which is still within specs and seldom a cause for concern. As always, we combined all 12V rails into one graph. This time it represents six 12V rails, which is why the graph is so thick. With six rails, the various outputs will never be identical, and we measured a difference of roughly 0.15V at higher loads. Despite the spread between the 12V rails, we still get a voltage regulation of around 3%, which is a very good result.






The 3.3V and 5V output quality is okay, and the 3.3V rail is the worst we'll see from this PSU with a ripple result of 14.6mV. 12V1 has the lowest ripple with up to 17.79mV while the other 12V rails reach up to 30mV, but the overall results are similar to 12V1.

    This is really horrible on Enermax's part. It was said that the PSU would be available at the end of the month (then Novemeber), at the latest; here it is the end of the first week of December, and the thing still isn't to be seen anywhere. Maybe Enermax will decide to bless us by making it available before Christmas.

    When you announce the availability of a product, it damn well better be available.

    I e-mailed Enermax and got a respond from them saying "The revolution should be available in about two weeks." That's December 22nd, or just around Christmas. So we'll see if that ends up being the case.

    Enermax PSU. My liberty 400w over spins the fan, So I pulled the fans cable out, and hooked it up to 5v, It's always quiet right around 800RPMs...

    My Q6600 dual 8800GT's runs on a 610w PCP&C silencer. There is only a few small situations were over 750w is necessary.

    So-far, this sounds great, but almost like vaporware (except Anandtech has an actual working sample). I mean, when will this thing be available? I'm building a new workstation for myself, and have held out purchasing the CoolerMaster 1200W UCP because of this new Enermax Revolution 1050W, which is modular. But I don't know how long I can wait. It'd be nice if Enermax gave us some kind of clue as to when the thing will be available.

    Enermax says that the first shipments will arrive at the branch offices in the end of this month latest.

    Good point, cause Hybrid SUVs are still SUVs and this guy is a 1050W powersupply... definitely an "SUV".

    This thing is really GOOD looking actually. To those of you who ask, why even write an article of a 1050W power supply? I say, this is an enthusiast's site... of course it should be covered.

    I unfortunately won't be buying this beauty, but if I were more enthusiast-like (kind of past the stage now sadly)I would certainly consider it. $330.00 is a lot of money, but it's not so bad. You figure in the things prone to become obsolete are video cards (two-cards at least for a system with this power supply yes?) Those will run $200+ each. CPU... say $300+, motherboard say $150-$200.00 and on and on. If you're going to do that sort of build you may as well slap this thing on there.

    I'm happy with my switch to the sub-$500 computer space for desktops. But it's boring, and this power supply isn't. I also own a Corolla, it doesn't mean a Lamborgini Murcielago is "irrelevant".

    Oh just in case you've been in a cave for a few years. $150.00 buys you an awesome video card. Even if you're old like me, you should really get one just for goodness' sake.

    I like the specs on this!

    Thanks for all the hateful comment. But as far as i read, even a CoreQX97xx with Geforce GTX 280, as stated in the Corei7 review, only uses 300W at peak. ( And Corei7 uses less then that )

    Double that, so you have a Dual Quad Core, Geforce 280GTX 280 SLI, you will still ONLY arrive to 600W at peak.

    So may be the article "Debunking the PSU Myth" never got enough people read it.

    And this may be the second dumpest question ever as someone would post.

    Yes, exploded - as in a shower of sparks, loud bang and the force was so strong it broke the plastic mounting bracket where the heat sink attaches to my CPU...

    Along with thousands of other people's Enermax PSU's exploding, I am very afraid to purchase another Enermax PSU. I used to be a stalwart supporter of them - they made great stuff. But... after hearing of others warranty'ing their PSU only to get another one, or a third one that exploded, I decided to move on to something else.

    I hope they have finally fixed these problems.

    how come don't you do step load tests?
    It would be really interesting and informative to see transient responses, settling times and overshoots. Please consider it.
