Ripple & Noise

There are no significant overshoots visible in the graphs. The fundamental oscillation is minor as well, which means very low ripple & noise. In addition the voltage always regulates itself around the same value. +5V reaches 10-25 mV at 100% to 110% load in our tests. The result at +3.3V is just marginally higher. 70 mV on the stressed +12V rail is just above 50% of the allowed tolerance. Here we have shown the worst case and the measurements are representative, so the results are fine. During all of the tests the oscilloscope showed no noticeable transients of the voltage.

    *raises hand*

    Low end PC, with a HD5750 for graphics. Build a couple of months ago, only needs a small power supply.

    That said, if the power supply hadn't have come with the NSK3480 case, I likely would have gotten a bigger power supply.

    Yes, I consider this kind of PSU since the first green series. It has been used in Antec NSK4480 case. I consider this a VERY good choice for corporate PCs.
    PS: Not every PSU goes under the reader's desktop.

    Umm I used an Antec 380 Earthwatts in my home server build.

    Dont knock Anandtech because of your short-sightedness you just make yourself look like a fool!

    Great review Anand this power supply is freaking awesome and definitely the best buy you can get for a unit under 400 watts.

    I got mine on the egg after rebates for $29.99 too!!!

    I'll raise my hand to this review. I was looking at purchasing this exact model a couple weeks ago for an HTPC.

    I used one of these for an esx server. Yeah yeah its not exactly a server PSU but its fine in a home environment. I wanted good efficiency since its always on and low cost, this thing delivers both!

    use a watt-o-meter on your rig and get back to us with your setup and wattage please...

    Maybe you will then like to reconsider reading this review...

    Although this might seem small, it is still too big in my opinion to be considered green. If you are claiming to be green, how about something in the 250W range, or smaller! A gamer is probably not going to bother looking at this article anyway because they think they need 1000W, even though they could probably do with much smaller. Come on it's like buying 94 Octane when most of us drive Corollas.

    I think its becaus there trying to target the mid range market as well ;) they mention something about it in the second to last paragraph in the conclusion... then again you can always check the first page of the review to they have a mention of it there to.

    "A gamer is probably not going to bother looking at this article anyway because they think they need 1000W ..."

    Most readers and gamers here are computer and physics literate people - not withstanding the ignorance of the second top-level commenter above - who know they only need 400 -700 watts for a high-end SLI/Crossfire gaming machine, and 200 - 300 watts for anything less. Many of us also build HTPCs for the home, and the occasional machine for friends and/or family, or advise them in their own purchases.

    You really should readjust your expectations and cliches in accordance with that.

    Well the series does include smaller models, and this is probably what Antec sent them.
