300W to 450W: 20 Power Supplies on the Test Bench

Seasonic S12II 330W
We tested the Seasonic S12II a while back and we liked it so much that we awarded it our Gold Editors' Choice Award. It seems that this series is not doing as well in the market now, since we have heard more negative feedback lately. Now that Seasonic announced an 80 PLUS Gold power supply series for early next year we want to have a last look of this fading series to get a better comparison to other units in this field. It comes in the typical black and with a ventilated back.
Both previously shown units from PC Power & Cooling and Silverpower are made by Seasonic and now we have the retail version from this manufacturer. The design is the same as we saw earlier, but this time we see better components and other small changes. It's clear that an ODM manufacturer also selling its own products wants to have the best components and technology for their retail power supplies. The main cap is made by Hitachi and the secondary caps also come from Japan and are made by Chemi-Con. Seasonic also includes all solid capacitors for the 12V rails. The fan is made by Adda, who supplies most of Seasonic's fans.
The Seasonic S12II 330W comes with the typical six Molex connectors and four SATA connectors. The 6-pin PEG connector is 60cm long, which is good if you want to guide the cable harness nicely through your chassis while trying to optimize airflow. The 24-pin connector is at 55cm, which is good for larger cases.

That is a heck of a lot of work for this article and we appreciate it immensely! Between this article and the upcoming mid-range builders guide (I'm begging...please get it out asap) you have reaffirmed for me this is the #1 site.Thanks again.

The breakdown of the cable connectors and the build quality descriptions were helpful. The power noise charts look useful as well.mino - Monday, January 12, 2009 - link
Copy that, one of the best PSU roundups around.magreen - Wednesday, December 31, 2008 - link
We definitely appreciate the roundup. It addresses our needs as consumers. I wish you'd add more info about the Antec Earthwatts 430 though... it's one of the most popular PSUs on the forums here and always shows up for cheap in the hot deals section, often bundled with an Antec case. Wish you'd give us more details on its efficiency, ripple, and your overall take. I don't think you actually said anything about its performance at all. Thanks!OddJensen - Monday, January 5, 2009 - link
Isn't there a Delta made version of the 430 as well?Christoph Katzer - Monday, January 5, 2009 - link

Thanks for this article. I am one of those who does modest OCing and no SLI, and this article was pertinent for me.eetnoyer - Wednesday, December 31, 2008 - link
No temperatures at load? I would think that temps at 100% load for each unit shouldn't be too much. Just as a worst-case thing.
