Our short list of recommended power supplies for quiet or silent computers, updated at least once a quarter. The update of Sept 8/09 is a complete overhaul. Gone are the finely graded numeric values, replaced by just two main categories: Editor's Choice and SPCR Recommended. Latest update Feb 19, 2011.

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.

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.

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.

We review and compare two fanless 500W ATX12V power supplies from quality brands. One has 80 Plus Platinum efficiency; the other sports Silver. In other ways, they appear similar, with the exo-heatsink design of so many passively cooled devices.

The only 80 Plus Platinum level PSU on the market, with over 92% maximum energy efficiency, is also said to be one of the quietest. We analyze the Kingwin LZP-550 for efficiency, electrical performance and noise.

Corsair's new AX850 has 80 Plus Gold certification for 90% efficiency, totally modular cables, a hybrid passive/active cooling for silent operation, and is backed by a 7-year warranty. It's perfect for a Silent Gaming Rig in a thermally advanced case.

A German affiliate of HEC, Cougar is offering the 80 Plus Gold rated premium GX series only in the EU at this time. How does the GX-700 fare against other Gold PSUs?

The TruePower series has been bread-and-butter for Antec for many years, but the line has recently received a refresh. Partly modular cabling, high efficiency, lower noise, and high quality parts are all promised in these new Seasonic-made models. How do they fare against the SPCR short list?

A roundup torture test of samples from every fanless power supply line in the marketplace instigated by the Seasonic X-400 Fanless, which cruised through 15 hours of full-load operation at nearly 60°C temperature in the "case". Which fanless PSUs can actually deliver rated power with virtually no forced airflow?

The Seasonic X-400 Fanless is based on the successful, 80 Plus Gold X-series platform introduced late last year. Company reps say the new fanless PSU was years in the making; ultimately, they had to await the development of a super-efficient platform. It was worth the wait.

The most efficient ATX12V power supply in the world with a sensible power rating is the Enermax Modu/Pro 87+ 500W. It's also the quietest, by a slim margin. Alas, finding one to buy is a challenge.

Nexus has had PSUs in SPCR's silent circle before. The NX-5000, a modest 530W model with fairly high efficiency, is the latest to enter the select winners circle.

The well-known memory brand morphed in recent years to become a major player in retail power supplies. While Corsair offers kilowatt PSUs, a 400W model rounds out the opposite end of its line.

In Enermax' seven (!) lines of power supplies, the Eco80+ is one of two tagged as "eco". The "Love our Earth" tagline on the packaging attests that "eco" stands for ecology, but its position at the low-end of Enermax' lineup suggests that "economy" might also be a relevant tag. How fares this modest PSU in these times of silent, 90% efficiency, $200 models?
