Power | Reference|Recommended
A reference article comprehensively discussing many aspects of power supplies and how they affect system noise, cooling, efficiency and stability. Also lists recommended quiet power supplies. This is a years-old article that has been updated numerous times. It remains the most popular article at SPCR, with nearly 900,000 reads as of April 2007. Last updated April 4, 2007.

A little over a year after our last major update, we've made changes extensive enough to consider this the fourth iteration of SPCR's power supply testing system. PSU reviews have been popular bread-and-butter articles at SPCR for years, partly because of our close attention to detail, fundamentally sound test procedures, good test gear and thorough acoustic analysis. It is also because there were few serious PSU reviews done by other hardware web sites. Now, we've added crossloading, low AC input voltage, and ripple testing to complete our mix of PSU tests.

Rosewill may be a house brand, but Newegg has enough muscle to attract strong partners. In the case of the Silent Night 500 Fanless 80+ Platinum PSU, Rosewill's partner Super Flower has given Rosewill a major win.

CA_Steve, an active member and a moderator in the SPCR forums, examined the 80 PLUS definition of efficiency as a % figure at different power levels, also defined as a % of the rated power of a PSU. Steve decided that this is too misleading and shows why power lost (as heat) is a better efficiency comparison tool. I've had the same thoughts for years, but Steve took the extra step of data-mining my/SPCR PSU reviews for the past half dozen years to demonstrate the above, and show various power efficiency trends and issues relevant for not only Silent PC enthusiasts, but anyone with a yen to minimize energy consumption.

The title says it all: A fanless 80 PLUS Platinum 92% efficient power supply from Seasonic, the company which pioneered super-quiet power supplies. Can this product meet the expectations of its eagerly awaiting fans? ADDENDUM, 5 Feb 2013: The Third Sample.

This 90% efficient 350W PSU was announced nearly a year before the entrance of the Seasonic G360, but hasn't made much noise in the marketplace. A close examination shows that the product is quite competitive with the new Seasonic.

The name is a big mouthful, which fits with the rest of the Dark Power Pro 10 550W — the big packaging, the big casing, and in the end, the big performance. Our first gander at a bequiet! PSU in years, and it manages to catapult past most of the traditional leaders, right to the top of our super-silent, high efficiency, high performance PSU list.

A Silent Pro M 700W power supply has been doing reliable yeoman duty in SPCR labs for years. We examine a new variant, the CoolerMaster Silent Pro M2 720W out of curiosity and not a little hope for more of the same.

A Platinum-efficiency (92%) power supply from Enermax, one of the oldest names in the computer power sector, promises superb performance and ultra low noise, like its earlier brethren, Modu/Pro 87+... at a price.

Seasonic introduces 80 Plus Gold efficiency PSUs in TFX12V form factor with semi-passive, hybrid cooling for mini-towers and compact media PCs. Will system integrators embrace these new 300W and 350W PSUs?

Power | The Silent Front
Six years ago we conducted an anlysis of power consumption and distribution in several desktop PCs. Today we repeat the analysis with three modern machines to see how things have changed.

The subject of our second KW power supply test in a row is an 80 Plus Platinum rated Kingwin vying for top honors among gaming silent PC enthusiasts. How does it fare against the Seasonic X1050 celebrated in a recent review?

Seasonic recently entered the ranks of kilowatt PSU makers with new 1050W and 1250W models in its X series, and a 1000W model in its new X-derivative Platinum line. Our acoustics-focused review of the 80 Plus Gold approved X-1050 finds Seasonic in fine form.
