- PC Power & Cooling
Both PSUs are cooled by a AD0812UB-A71GL from ADDA, a very common brand for Seasonic-made products. The 910W model has larger main caps but overall it is the same layout as you can see on the pictures. Since the original S12D was a 750-850W design we assume our 760W sample will show a better performance later. This Interior is a great base for a PC Power & Cooling PSU since Seasonic offers a high-quality PCB, Japanese capacitors (Nippon Chemicon and Rubycon) and two very large heatsinks. The EMI filtering is well equipped and includes a MOV. The DC-to-DC VRM are realized on one PCB and use all solid capacitors from Nippon Chemicon.
There is not much space for cooling. Specially in the primary circuit where many chokes are glued together. The main transistors are two IPI60R125CP with a moderate drain-source resistance of 125mΩ. For rectifying on the secondary circuit Seasonic has implemented eight 40S45CT -- more than enough to provide 760 or 910W. In fact the conducting path behind are often weaker than the transistors and/or diodes for rectifying. Nice too see that this design has a 70 μm copper layer. The smaller version has a 12V coil with a HF litz wire.

opc - Tuesday, August 2, 2011 - linkI have a five year old version of the 700W PSU, and it is the only component in my PC that has never once given me a problem, and never once needed to be upgraded. I remember hesitating before pulling the trigger because it was a little more expensive, but I'm really glad I spent a little bit more because it has been well worth it.
The PSU has been running SLI video cards (7800GTX -> 8800GT -> 460GTX) its entire life, along with a power hungry processors (Q6600@3.6GHz) and usually several HDD's and SSD's of various types over the years. It has never missed a beat in all that time.
I really wish there was a product like this in every segment of the PC industry. I've had countless problems with motherboards, memory, HDD's, SSD's, and even processors on occasion. If I could spend a little more on those other items and know that they would last without giving me grief, then I would do it every time.
Hopefully these PSU's are just as well made as they used to be, and if they are, then they definitely get a glowing endorsement from me!

Spazweasel - Wednesday, August 3, 2011 - linkHole cooling is important. That painful burn can be a real buzzkill.
raejae - Tuesday, August 2, 2011 - linkThis is entirely meant as constructive criticism... but it seems this article was checked with a spell-checker and nothing else. The grammatical errors, misspellings, and sentence structure make it nearly unreadable... which is disappointing, because I'm very interested by these power supplies.
cgramer - Tuesday, August 2, 2011 - linkAgreed. I think AnandTech needs to get one or more copyeditors on staff. Despite that, I still love their reviews. :-)
SilthDraeth - Tuesday, August 2, 2011 - linkI believe English may not be this reviewer's native spoken or written language. I admit it was a bit difficult of a read, but really, it is a psu review.
As long as the numbers on the charts look good. And the conclusion fits the bill, then I believe stressing over the oddly structured sentences is wasted energy.
cgramer - Tuesday, August 2, 2011 - linkI'm not stressing over it, really. I'm concerned mainly about AnandTech's image. Poorly-written articles (even if they're impressive for having been written by a non-native English speaker) reflect poorly on a site's or publication's level of professionalism. I'm noticing a lack of proofreading and editing in lots of publications lately, including extremely popular print magazines such as Motor Trend or Automobile. It's a shame, really, that quality of writing doesn't seem to matter as much in this online age.
As I said earlier, though, despite the sometimes-rough writing, I do love AnandTech. It's the first place I go for in-depth reviews of computer-related products. :-)
Meghan54 - Tuesday, August 2, 2011 - linkCompletely agree. I've always said this place could use just one competent copy editor. It'd make a world of difference in the professional image of AT, not to mention making the articles an enjoyable read instead of the tedious work it sometimes is right now.
ajtyeh - Tuesday, August 2, 2011 - linkSweet deal, it was on slickdeals yesterday, and a bunch of people got in, i cant belive you guys did a rewview right after i bought it. i have never known the reliability of PC power and cooling but after you did this review, it got rid of my buyers remorse.
