External Impressions and Cables

The appearance has not changed much from Rosewill's 80 Plus Gold Capstone series; the Fortress comes with a rough sandblasted texture that reminds us of some Enermax PSUs. The angular fan grille is black and the silk-screened Fortress logo can be found on both sides. As usual, the entire back is perforated to provide maximum airflow. A power switch can be found directly below the power input. The unit is quite long for a 450W model at 163mm, so it is probably not the perfect solution for HTPCs.

Cables and Connectors

Connector type (length)

Main 1x 24-pin (55cm) fixed
ATX12V/EPS12V 1x 4+4-pin (65cm) fixed
PCIe 2x 6/8-pin (50, 65cm) fixed
Peripheral 3x SATA (ca. 50, 65, 80 cm) fixed
3x SATA (ca. 50, 65, 80 cm) fixed
3x Molex (ca. 50, 65, 80cm) fixed
2x Molex, 1x FDD (ca. 50, 65, 80cm) fixed

There are five Molex and six SATA connectors attached—quite a lot for the power rating. Moreover there is a very long 4/8-pin cable for the motherboard and two plugs for a graphics card; the long ATX12V/EPS12V cable is particularly important for cases with bottom-mounted PSUs. You won't be able to run an SLI or CrossFire setup with the highest performance GPUs, but two 8-pin PEG connectors are exactly what we would expect from a 450W power supply. In addition all peripheral cables are long which is helpful when using a Full Tower, and all the cables have the same black cable sleeving. If you're planning on building a smaller mATX system, the fixed cables and their lengths might be too much, but for ATX cases that shouldn't be a problem.

    Minor gramattical error on the final page:
    but the Rosewill Fortress 450W is currently one the most advanced consumer power supply available.

    Forgot an "of" after one... Thanks for the great article though!

    you guys are such fagets
    i read this just fine
    if you get pissed off over gramatical errors on the internet
    you're going to have a bad time

    That's because you're reading it after the editing. I'm reading it again now, and I agree that it does read fine now. Thanks for the improvements AT.

    Was challenged to find a good PS under $100 and shopped for single 12v rail unit.

    More challenging than I anticipated, but much easier to wade through than the benenfits of bronze vs platinum vs gold ect. Customer loves Seasonic and usually buys their Platinum 850W .

    Ended up with another Seasonic : SeaSonic M12II 650 SS-650AM 650W BRONZE Semi-modular . Good quaility and happy client.

    Got lucky was on sale, and dropped pretty close to disty price without a min or freight .

    In my tired Core i5 750 running a Rosewill 600W $40 special - with no big video to drive and no other PS below $70 really standing out has been a budget driven decision that has held up.

    "In short, Bronze gets you 95% of the efficiency of Gold for about 2/3 the cost, and 92% of the efficiency of Platinum for about half the price. A typical system that draws around 75W at idle would save 8W going from Bronze to Platinum. At that rate and paying $0.10 per kWh, you save $7 per year when running the PC 24/7. For servers and other PCs that are on 24/7 already and consume a lot more power, efficiency can make a lot of sense (e.g. power savings of around $40 per year for a 500W server using the same $0.10 per kWh), but for home users there needs to be something more than just pure efficiency to make the increased cost worthwhile"

    Why ON earth must a PSU treated from a economical viewpoint? Just because there is a saving dosent mean that that have to be compared to the investment? Are PRIVATEs now all bound to corporate investment rules? A PSU is one of few products you can buy were it is possible to save energy / money, still it is a PRODUCT and should be treated as a iPHONE or a any other product. Do you private buyer have any other source were you can do savings/investments at a higher rate / lower risk than a PSU? Therefor leave all discussions of pure savings OUT of the reviews of PSUs.
