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).

    Also not trying to be a jerk. If you're going to talk about how expensive it is on the first page, then tell me the price. I had to search for it and then finally found the price listed on the last page. Reply

    In the article it states that the warranty length is 5 years, however according to Rosewill's product page the Fortress-450 has a 7 year warranty.

    Article is not consistent with itself:

    Page 2 says "7-year warranty"
    Page 6 says "5-year warranty"

    Warranty is 7 years according to Newegg, as well. Reply

    I have to agree with the other commenters. This article is well below the quality level I've come to expect from Excepting the images, every aspect is substandard. The edits in response to the other comments helped, but several parts (esp. the conclusion page) are still painful to read. I don't recognize the author, and I don't want to hate on him; however, this article reads like a very early rough draft. Reply

    Very good review, despite grammar patrol,
    Rosewill is doing very well in price/performance/quality here. I also find the Capstone line moredesirablee in price, especially when discounted.

    bottom of page 2, change 37W to 37A. Reply

    page 6: "performancs" should be performance. Reply

    I do appreciate the breakdown of where exactly each connector is on each cable.

    But I would like to see more punishment of the PSUs. How do they hold up in extreme situations?

    There have been reports that some PSUs don't work well with square-wave UPSs.

    Do they hold up in hot conditions?

    How do they handle low voltage (brownout) conditions? (say 90V)

    How do they handle voltage swings? (Hook them up to a variac, start twisting the dial and see what kind of transients you can generate)

    If they face a large load at once (say a bunch of hard drives spinning up simultaneously), how does it maintain the voltage levels?

    If you short out a cable, will you blow up anything?
