Appearance, Power Rating and Fan

The PSU has a black finish and honeycombed ventilation holes. There is no typical fan grill but the casing has many holes punched in it. At 160mm, the case is moderately long. As usual these days, there is a power switch next to the mains plug. Because there's a fan for cooling, this PSU has fewer ventilation holes than the X-460FL. Modular cables can be mounted on the connector panel at the front, and as usual Seasonic's overall build quality is very good.

Seasonic still believes in powerful single rails. On +12V this PSU can deliver nearly the full power since step-down-converters are included for the smaller rails. +3.3V as well as +5V are rated at 125W and/or 25A maximum load. Both have the same ratings as the ones from the older 750W version. That would mean the same kind of components are used here and the voltage drop should be low. At 3A, 5VSB is relatively powerful as well.

The San Ace 120mm 9S1212F404 has seven fan blades and ball bearings; it is not PWM controlled. There is a shield to direct airflow so turbulences near the ventilation holes are eliminated. Owing to the low rotation and passive mode under 20% load, the fan shouldn't wear as much as other fans do in actively cooled PSUs.

    To the comment about velcro straps: this model comes with 3 velcro straps with a Seasonic logo on them.

    I have three of these PSU's running from a low wattage router (brazos) to a high wattage desktop (4 core phenom.) One of the PSU's i received was DOA. The Seasonic RMA process is a single html page on their website that unfortunately does not yet include the serial numbers for this particular model in the java script validation logic. Therefore all RMA's have to be emailed and approved manually, which took over a week for the first response. Luckily for me, the NewEgg RMA process is much better than the Seasonic RMA process and within a few days I got a working replacement via NewEgg.

    First off, Excellent review.
    I greatly value your expertise, and picked up an Antec TP-650 based off your review.

    Minor editing changes:

    <first page>
    Even most of the S12II and M12II models (which they don't generally offer as review samples) are getting awards all **other** the world for providing high quality in a mainstream market segment.

    ...all **over** the world...

    <last page, second paragraph>
    **Stargin** with the connectors, Seasonic shows an instinctive feeling for different...


    I appreciate your reviews and have used them when making purchases on more than one occasion. Thanks!

    Done, thanks a lot. Reply

    Dear Editor,

    I remember seeing a power supply review in the past that had a diagram of the length of each cable. Such a diagram would be very helpful in the future for making purchasing decisions, especially for those of us with cases where the power supply is far away!

    Otherwise, great review! Keep them coming!

    Martin, could you do some testing of Titanium-Standard PSUs... specifically around the 1kW mark. There's only T-Standard available at NewEgg, which I think is around 500Watts, but if you could contact the vendors and get the 1kW versions - that would be nice.

    Your readers appreciate when you all analyze products that aren't/won't be available at NewEgg - me especially :)

    In the past, if I remember correctly, the numbers for 230V were included in your reviews here Martin, not only 115V for the american net. Why did you change that? I know this is an american site, but the audience is international ... .

    It would be no problem to add these measurements next time.
    With this I just have more work and I didn't know, that 230VAC results are interesting for some readers here. Good to know.

    Grüße zurück.

    Reviews like this are why this site is more credible than many of its competitors. Reply

    maybe, but nothing is more fun than reading OklahomaWolf tearing into a cheap piece of junk. Reply
