Package Contents

Seasonic offers a few  extras in the package to sweeten the deal. Besides the standard power cable and four screws, you get some stickers, a big user manual, and all the modular cables come in a bag. The "important notice" you can see above states that the PSU "is designed to be responsible for its own cooling". No more, no less.

The X-460FL has a fully-modular connection panel and a description for every plug-type. The main 24-pin cable uses two of the plugs (the large 18-pin connector, and the 6-pin connector next to it).

Rated at up to 456W, the +12V rail can deliver nearly the full power of the PSU. +3.3V and +5V are rated at a maximum capacity of 20A each, with a combined output of 100W. Like most modern high-efficiency power supplies, Seasonic has DC-to-DC converters inside.

    Don't know why I never posted a comment sooner, but I got one of these ages ago, and it's still going strong over six years later.

    It's been used in two different builds now, and currently in use for a small form factor gaming PC, in a Rajinteck Metis case, which mounts the full-sized ATX PSU vertically at the front. While I'm not going fanless, this arrangement actually works really well for this PSU, as my CPU cooler is able to draw air in through the PSU before exhausting it out the back, which is fine, as with the PSU's high efficiency it doesn't generate much heat at all, and I have just a single fan cooling everything currently in my system, making it nice and quiet.

    In future I'll be adding discrete graphics (I've gotten a lot of mileage out the Ryzen with Vega's onboard GPU so far), so that'll be a second fan, it will also be pulling air through the PSU and exhausting it at the back, so I don't expect any issues. Plus the PSU easily gives me the headroom for that.

    In such a system as PSU with built in fan would either starving the interior of the case of air (by pulling from inside) or pushing air into a tiny case that only really needs a good exhaust fan to guarantee good airflow.

    Sure, it was a hefty price tag for minor benefits, but I've been pleased with it, and will buy fanless again if I can get one to the same high standard (or better).
