Internal Design

ATNG makes the electronics this time, but 80 Plus Platinum power supplies are almost always the same. In fact the PCB looks like a modified Golden Green (Super Flower). The core is an LLC resonant converter with synchronous rectifying on the secondary side, and there's a DC-to-DC converter at the far right as well to improve voltage regulation. Another advantage is the high 12V power rating. The filtering stage is located on a small sister PCB near the bottom of the picture and includes all the important components.

An IC offers most safety functions for all outputs and the primary circuit has some protections too; nevertheless, overcurrent protection is missing. There are two large heatsinks instead of the usual three, but all the current MOSFETs have a low power dissipation. Soldering quality is satisfying, and we couldn't find any dry soldered joints, though a few parts did get a bit too much solder. On one pin we found a bad wetting angle caused by the excessive use of solder.

    Not to be a dick but there are so many grammatical errors and awkward or fragmented sentences in this article that it made it hard to read.

    "convert to an 6-pin connector"
    "According to that Rosewill stands up to Antec."
    "At best GlobeFan is slightly better than Yate Loon, but we don't want to overdo things." ??
    "All cables got the same black cable sleeving."

    These are just a few examples. Maybe I'm being nit-picky but one of the reasons I read this site is for well written, well thought out articles and I did not feel this article was either of those.

    Seconded. I had to re-read the first sentence "Since we've had a ~40$ PSU roundup of late" I questioned if it should have read "we haven't had." Perhaps "Since we've had a ~$40 PSU roundup recently" would have made it more clear. Reply

    We know from previous reviews/comments that English is a second language for the author. Most of us would be hard pressed to be write as fluently in a language outside of our native tongue.

    I appreciate the author's considerable knowledge of power supplies, including fans, bearings, and internal components - minor grammatical errors or awkwardness aside.

    I also get agitated when I read poor English, especially when sentences could be interpreted in two different ways depending on how I try to "fix" then in my head. But you know what? Screw it. It's a great review from someone who knows their stuff, and I'm paying for it with little more than my free time.
    Keep on writing articles like these, grammatically correct or not.

    Sorry -- Martin posted without going through one of the native-English speakers. I'm editing/proofing the article now, but it will be a couple hours before I can finish. Thanks for your patience! Reply

    The Ripple Results link at the very end is wrong, it goes to the admin side, instead of the public side. It should be http://www.anandtech.com/show/5698 Reply

    Fixed, thanks! I didn't check all the URLs as I didn't expect any to link to our admin pages. :-) Reply

    Agreed. This is quite bad. Reply

    Still? I just finished editing, so if you find any major grammar/spelling issues remaining please let me know. Reply

    No, it is much better! Thank you for your editing prowess, sir. Reply
