    Can you explain beter the Voltage Ripple and Noise graphs?
    I really cant get it! Where is the graph scale?

    I was trying to find a good PSU and found this review.

    When you say: "The actual Power Supply Design Guide specifies that each +12V rail should not have any ripple over 120mV and the +3.3V and +5V rails should not have any ripple over ~50mV."

    Means that each power rail should not go outside this interval:
    11.88V < 12V < 12.12V 120mV
    3.25V < 3.30V < 3.35V 50mV
    4.95V < 5V < 5.05V 50mV
    Correct?

    How can 12.17V fall inside the specified range? "The 12V rails of the OCZ ModXStream tended to be high, but this is still acceptable as they fall inside the specified range."

    4.75V is inside the specs? and 5.13?
    "The 5V rails also remain within specs, but the last two units (OCZ and Amacrox) are very close to the lower boundary at 100% load."

    So what are the exac boundaries, or the voltage interval for each power rail?

    thanks

    I noticed the Cooler Master reviewed was the M850 ESBA modular version of the RS 850 EMBA. Seeing as how it is impossible to find that model in the US, I am wondering if the model reviewed was either a EU version or a new model Cooler Master is planning on introducing in the near future and also whether the internals of the US EMBA 850watt version are the same. Reply
  • jonnyGURU - Friday, December 14, 2007 - link

    The Cooler Masters are identical. Cooler Master refrains from selling the modular version in the U.S. due to Ultra's patent on the modular interface and threats to sue. You CAN buy the Cooler Master modular here in the U.S. if you get it bundled with a case. I've seen it pre-installed in some Stacker units over at Newegg. Reply

    I know im getting old and the old brain isnt what it used to be, but did'nt i read somewhere about dwindling oil reserves, skyrocketing oil prices, depletion of the ozone layer, and the need to reduce energy counsumption and be the green movement? I even thought I saw a trend with cpu makers trying to lower energy counsmption of their cpu's.

    You would'nt think any of this stuff was real when you see the trend towards bigger fuel guzzling SUV's and now a article like this - why on earth do we need kilowatt power supplies for a PC!

    If I was in government id have these things banned or else slap an enormous tax on them.

    People need to wake up and smell the roses. Its obscene that a PC should need a power supply over 300 watts. Even thats extravagant.

    A PSU only puts out what's asked of it. So if you're PC only uses 300W, the PSU only puts out 300W. Really the only drawback here is that larger units typically cost more to buy, and neither you nor I are in the position to tell someone how to spend their money. ;) Reply
