TTGI’s 420SS is virtually identical to the 520SS, but with 2 fans.  It comes with the same glossy finish, plastic ATX sheath, fan control, and 4 color LED fan exhaust. 

Some TTGI units are starting to ship with detachable Serial ATA cables.  Most SATA drives come with these same cables, so purchasing a power supply because it has SATA connectors is not really a smart idea.

Statistically, the 420SS is about average.  The +3.3V rail is not sacrificed, and the +5.0V rail is lowered significantly from the 520SS version.  You will loose about 50W on the +12V element, so if you need the extra juice for a video card you may want to rethink dropping down to the 420SS.  TTGI also offers an EPS12 version of the 420SS, which is basically identical to this model but with a 24pin ATX cable.

The selling point in this unit is also its relatively low price. This unit sells for $50, and thus makes it fairly feature filled. The tradeoff in performance comes later, but we will get to that later.

    1. No amp measurements were listed, a serious deficiency because without them there is no way to know how well each PS met its amp specs, and many brands are known to fall short.

    2. No overload testing results for shorts, excessive power draw, excessive temperature.

    3. Ripple is not just slow voltage variation also short term variation, such as for each AC cycle (60 Hz for the incoming AC, about 60,000 Hz for the output DC). I would have liked to see how the latter correlated with the memory noise test results.

    4. I hope you were careful when you tested the PS heatsink temperatures because some heatsinks are live with high voltage.

    Well for the observent people who can differentiate between orange and blue, its not an issue. Also waiting a full second before clicking it reveals the location on both the bottom left and the mouse cursor. but i can see how it does get annoying.

    yeah those in page advertisements are REALLY annoying...those have got to go. i never know when i'm going to link to another anandtech article or to an ad...i guess that's the point but it's still unacceptable

    I would like to see the review include a Heroichi Electronic power supply, I hear they are very good but I haven't used one.

    Some of your "In Page Advertising" links seem to be missing closing links tags or something so that it results in having a <link> in the middle or end of a sentence. Ex. "We had a lot of troubles with Vantec’s last power supply, the Stealth. We found an error in the production label<link>, which quickly led to a change in all the labeling on all Stealth power supplies."

    #3 and #4, thank you for spotting these errors. I have updated and fixed them.

    Cheers,

    I hope the ripple for the PC Power & Cooling 3V wasn't 2.295.. Possibly 3.296??? 1 volt drop is unacceptable.

    a little more content per page in some cases would be nice too...

    ...but good to see content on the site at all...and seemingly more regularly too...
