Seasonic X-Series 560W
Our latest candidate for PSU torture testing is the Seasonic X-560. Seasonic first garnered praise with the X-Series by offering a range of 80 Plus Gold PSUs from low wattage up through high wattage units, along with two passively cooled versions. Other reasons for their popularity are the 5-year warranty and outstanding internal design. Even most of the S12II and M12II models (which they don't generally offer as review samples) are getting awards all over the world for providing high quality in a mainstream market segment. At a price of $120 USD the X-560 is definetly not the cheapest ~550W power supply, but we're here to find out if buyers get more for their money.
As you can see in the picture Seasonic delivers a bag for modular connectors—the X-560 has fully removable cables. Also included in the packed are a power cord, four screws, a user's guide, and many cable ties. In short, Seasonic provides plenty of extras to keep the customers satisfied.
A note on the PSU informs users that this PSU works passively below 20% load. Features include "tight voltage regulation", "gold plated terminals", and a mainboard with many SMDs (surface mounted devices). High-class solid caps are part of the ouput filtering. And for the gamers among us, this PSU supports multi-GPU technologies, all with a reasonable rating of 560W.

JohnnyGuru is where it's at for PSU reviews.
Badcapt.net is alos a pretty handy resource.
Anand for SSD's FTW! :-)

piroroadkill - Wednesday, March 23, 2011 - linkYesss, I do love JonnyGuru for OklahomaWolf's style.
jabber - Wednesday, March 23, 2011 - linkWouldnt it be better and more reliable to have the main power input lead actually hardwired into the PSU rather than through a connector?
After all thats the one lead you are going to use.
7Enigma - Wednesday, March 23, 2011 - linkI was thinking the same thing. Other than the coolness factor of being able to transport just the power brick I don't see a purpose and there is sure to be a minute penalty to efficiency by having those modular.
strikeback03 - Wednesday, March 23, 2011 - linkIf they sell different length cables it is nice, for example with the provided 24-pin cable the length is great if you have a bottom-mounted PSU, but it is a lot of extra to hide if you have top-mounted. If they made a shorter cable for top-mounted cases it would be a benefit.
somedude1234 - Wednesday, March 23, 2011 - linkI've done a build with this PSU, and I appreciated the fact that all of the cables were modular during the build process. Not having the bulky main power cables getting in the way until I was ready to route them properly was nice.
Also, based on the results it doesn't look like the performance is suffering.
djc208 - Wednesday, March 23, 2011 - linkThink I found the PSU for my next upgrade! This or the passive version might be a good idea for my WHS too.
Ptaltaica - Wednesday, March 23, 2011 - linkGreat review Martin, but there's one thing I wish you had emphasized a bit more-the significance of that Sanyo Denki fan.
We all know that most power supplies use cheap, crappy fans; even the ball bearing ones in most units are Chinese-made garbage of questionable quality, and in my experience fan failure is the cause of an awful lot of power supply failures.
The Sanyo Denki fans Seasonic is using in these units, by contrast, are some of the most reliable, longest-lived and highest quality fans on the market. The impellers are balanced with little blobs of epoxy to minimize wobbling and subsequent wear on the bearings, and they have some of the tightest and lowest-drag bearing assemblies I've ever seen; the only other companies that are in the same quality ballpark are Nidec and EBM-Papst, in my opinion. Delta, Adda and NMB-MAT (aka Panaflo) are decent, but even they're not as good as Sanyo Denki, Nidec or Papst. And everything else is pretty much garbage.
As far as I can tell, the 9S1212F404 in this PS is a tachless variation of the F401 (datasheet here: http://db.sanyodenki.co.jp/product_db/cooling/dcfa... ). The F401 has a MTBF of 40,000 hours... And that doesn't sound like a lot compared to what some companies advertise. Except that that rating is with a 90% survival rate, and rated at 60*C. Rate it at 25*C or whatever like a lot of companies do and it's probably closer to 160-200,000 hours, if not more.
Given that it only runs intermittently in the X series power supplies, I can easily see one of these power supplies lasting 10-20 years or longer. There are very, very, very few consumer goods of any kind these days that can legitimately make a claim like that, and-thanks in large part to the SD fans-the X-Series power supplies are the only PSUs I've seen that can.
i think the relatively small price premium for these units relative to other similarly-sized PSUs is worth it on that fact alone; I've used the X-Series power supplies in every computer I've built at work since they came out, including any of our servers that do not require redundant power supplies, and I'll continue to use them for as long as they'll make them.
