Five 550 And 600 W 80 PLUS Platinum Power Supplies, Tested

Enermax Platimax 600 W

Back in the summer of 2011, our news team saw the Enermax Platimax line unveiled at Computex, and it left an indelible impression. Enermax sent us a 600 W Platimax model for this round-up, and its packaging and workmanship are as impeccable as what we witnessed at the trade show in Taipei.

The Enermax Platimax 600 W has three 12 V rails, each of which can handle up to 25 A. Together, the three rails are rated for up to 600 W, which is the power supply's total rated output, too. We were able to draw 600 W from the three 12 V rails without any adverse effect on the other voltages.

This power supply has plenty of connectors: eight SATA, eight four-pin Molex, and four PCIe. The cables are partially modular, meaning that only the mandatory motherboard and auxiliary CPU cables are permanently attached to the unit, and cable length is above average.

    Is that a typo in the first chart for Kingwin's Lazer? It claims that it fails 80 Plus's 50% load spec (82% of 92%); I assume that was meant to say 92% (since that's what the chart below it shows).

    Pleasant read, though, I like PSU reviews.

  • What happen to Seasonic? They have the 520W fanless SS-520FL Platinum version. No PSU test is complete without a seasonic to compare to, in my own opinion.

    jupiter optimus maximusWhat happen to Seasonic? They have the 520W fanless SS-520FL Platinum version. No PSU test is complete without a seasonic to compare to, in my own opinion.they asked for vendors for the PSUs. Theres the offshoot chance that seasonic declined the offer. On other sites, the 520w fanless seasonic unit was compared to Rosewill's 500w silent night unit. The seasonic unit I believe in that review barely edged out a victory.

    iknowhowtofixitEither the Rosewill FORTRESS was defective or your calibration was off for the last test. Your o-scope shots do not match those of other highly credible reviewers. Also, I'm curious of your testing methodology, but it was not listed.I believe this is still applicable to all of the power supply testing our German team does: http://www.tomshardware.com/reviews/psu-test-equipment,2657.html. I'm waiting for confirmation that I'm right.

    Edit: Yup, that's the correct testing equipment/procedure!

  • Dun dun dun..................... no acoustic performance measured, the only reason some people buy high end PSU's.

    WOW! Thanks a bunch for including the 25watt "Low-Power PC" efficiency test! All other reviewers stop @ 20% load witch is not "idle" or "low load" at all. :-)

    Power supply unit is where a system builder cannot use a word "BUDGET"

    I don't understand
    Why is the 80 plus spec officially test by having more load on the 3.3v and 5v rails?
    Clearly loading the 12v rail would give us a better overall image

    Interesting, IMHO the most important aspect is 'Ripple Voltage' @ Rated Load. The only mention I see is a vague reference in your conclusion page.
    Never mind I see the ripple data buried in the individual tests. It would have been better in the summary side-by-side tests.

    Nice article.
