The Seasonic G360 review posted here a few weeks ago raised lots of interest in the forum discussion, and generated over 20,000 reads in just a couple of weeks. This demonstrates clearly that many DIY PC builders are hungry for good lower rated PSUs. I mentioned in that review that there are several other PSUs that fall into this category: The AURUM GOLD 400 from FSP, the Magna Platinum 400 from Sparkle Power, and the Golden Green 80 PLUS Gold 350P14XE from Super Flower.

I had an opportunity to speak directly with Super Flower reps at Computex in Taipei last June. They confirmed that the Super Flower brand is not available in the US and Canada, which are defined as Kingwin territory. Kingwin has no plan to import the 350P14XE under its brand to North America, even though the product has been available for about a year. I persuaded Super Flower reps to ship a sample to me in Canada, as some 60% of the SPCR audience comes from outside North America. The sample arrived a few weeks ago, but searching on the web today, I can only find pricing information in Korea. It's obvious that this model is not getting broad global distribution. The selling price in Korean Won is the current equivalent of US$62~65, which is about what the Seasonic G360 sells for in the US.

The 350P14XE is only the third sub-400W PSU to be reviewed by SPCR in many years, and only the second ATX form factor. The significance of these products are worth reiterating. From my G360 review a month ago:

"Everthing comes and goes... and comes around again! When I first started reviewing computer power supplies a decade ago, a 300W PSU was considered quite powerful, and 400W was about as high as the ratings went. Then came 130W CPUs and multiple >200W video cards for gamers, and kilowatt PSUs. For a while, it was hard to find any retail packaged PSUs rated for less than 450~500W, and 600W seemed to be the new norm.

"The good news is that the power race over the past decade was not for naught. It was accompanied by dramatic increases in power supply efficiency from well below 70% at the start of the period to over 90% today (virtually mandated for effective cooling of PSUs approaching kilowatt rating), a steady decline in CPU power demand as Intel (and AMD, to a less successful degree) got seriously focused on energy efficiency, and most recently, significant improvements both integrated graphics performance and the power draw of high performance discrete graphics as well. As a result, the typical power requirements of modern desktop PCs are about as low again as during the era of Pentium 3, when 250~300W PSUs were the norm. It is in the context of these trends in PC component technology that we can fully appreciate the introduction of the Seasonic G360 [and now the Super Flower 350P14XE]."

PRODUCT DETAILS

The 350P14XE is marketed as "Golden Green", which apparently refers to the 80 PLUS Gold rating and the "green" eco-friendly aspect of its high efficiency. Being a lower power model, it cannot be marketed as high end, and the packaging reflects the cost conscious, "value" positioning. The Golden Green line is extensive, with a dozen models going up to 1300W output. Curiously, this 350W model is no longer listed on the Golden Green page. I've sent a query asking whether the product is permanently discontinued, but have yet to receive a response. The next model up is a 400W, and shamefully for Super Flower, there's a 430W, a 450W and a 500W model. This calls for a serious rant: It is horrific hyper-consumer marketing at its worst. The simple fact is that if a 400W model isn't quite enough, it is sensible to get a 500W model. These multiple models differentiated by the merest wisps of power ratings satisfy only the paranoia of some marketing obessive and/or the minions who serve the executive, and serve no real customers at all. What a waste!


The retail box is small, compared to many others we've seen. An aside: Super Flower's butterfly logo has always been a bit confusing to me, but I suppose the allusion is to a flower's attraction for the bugs.


The PSU, whose output cables are all attached, comes packed in a bubble wrap bag, with an AC cable, mounting screws, and a thin user's guide. The simplicity is a fresh change from uber-marketing.
