Results are measured under room temperature using 115VAC. +12V starts very high since the tests are conformed to ATX standards. As expected, the 12V rail shows low drops and handles up to 41A as well. +3.3V and +5V are well regulated and not too weak. 5V in particular is very stable with only a small difference between 10% and 110% load.

Maybe we should stop measuring ripple and noise for Seasonic products since the results make their opponents angry. We've used up all of the positive words in our vocabulary in other Seasonic articles, so we'll just repeat what we said in the X-460FL review: The voltage quality is absolutely flawless. Small transients are no big deal for 3.3V and 5V, and +12V hardly has any noise at all. In short, this is an excellent design.

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 http://www.anandtech.com/show/3985/three-550w-psus... 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...
**Starting**...
I appreciate your reviews and have used them when making purchases on more than one occasion. Thanks!

Done, thanks a lot.Drag0nFire - Tuesday, March 22, 2011 - link
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 :)

Hi!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.DanNeely - Tuesday, March 22, 2011 - link
maybe, but nothing is more fun than reading OklahomaWolf tearing into a cheap piece of junk.
