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

FSP OEM 300W
Companies such as FSP do not sell these so-called OEM versions directly in the market. Instead, they find their way through various distributors and e-tailers to end-users. They come without any packaging or warranty because the companies want to keep this service strictly to their retail version of the product.
Opening this unit reveals an older topology with passive PFC. There are two main capacitors in the primary with lots of glue around them. The secondary uses Ostor and Teapo capacitors and again lots of glue, which seems to be everywhere in this unit. OEM units don't need to look cool or shiny as we can see with this product here. The heatsinks are small and just might manage to dissipate the heat a 300W PSU can generate. Somewhat funny is the use of a Yate Loon Electronics fan, even though some people see this manufacturer as a high-end option. Obviously, they also offer more economical fan options.
FSP didn't include very many cables and connectors since it is only 300W and an OEM version. Normally companies order power supplies like these to mount them in systems. The manufacturer can vary the length of the harnesses and the number of connectors as the system design requires. The ATX-300PNF comes with a 30cm main ATX harness and the extra 12V connector and the rest of the connectors have a similar short length.

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
Yes which we didn't have.Christoph Katzer - Wednesday, December 31, 2008 - 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.
