Delivery Contents and Specifications

The power supply comes in a dark box with various product specifications listed across all the sides. The package prominently displays the 80 Plus Platinum certification, which can certainly help attract potential buyers. 90%/92%/89% efficiency at 20%/50%/100% load are the requirements and these values are difficult to reach. In addition Rosewill offers a 7-year warranty. Features include the special black coating and the single 12V output. All the necessary extras for installation are present, including the usual stuff like a power cord, screws, manual, and several cables ties.

At first we were not able to identify the manufacturer of this fan as Rosewill is the only name we saw on the label. However, the model number RL4ZB1352512M indicates that GlobeFan is the company behind this product. This is a ball bearing type which takes 0.28A. At best GlobeFan is slightly better than Yate Loon, but it could have been worse since many brands still use sleeve bearings—even in expensive PSUs.

The Fortress has one 12V output, which can be loaded with 37A according to the manufacturer. Almost the full power is provided here because of the DC-to-DC VRM. The 5V and 3.3V combined output power is just 100W, but even such ratings are enough to power a modern PC. +5VSB can handle 2.5A (or 12.50W).

    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
