be quiet! Dark Power Pro 430 power supply

Power
In all the noise generated by all those who wish to grab a bite out of the expanding quiet computing pie, it often seems that the number of really quiet products hasn't grown that much. There's just a lot more "quiet" marketing BS to wade through. Thankfully, this "be quiet!" Dark Power Pro power supply is an addition to the genuinely quiet group. Alas, it's only for 240VAC!

Seasonic Goes High End Gaming with the M12

Power
Seasonic is going after the high end gaming market with the M12-700, a modular power supply that has everything: 80 Plus certification, 700W capacity, four PCI express connectors, and Seasonic's excellent reputation for noise. Oh, and a >$200 price tag to match. Is there an M12 in your future?

Seasonic S12 Energy Plus: Efficient Power for Connoisseurs

Power
The S12 models have been the quietest, fan cooled, high efficiency ATX power supplies reviewed by SPCR. Now, 80 Plus approved versions are available for certified high efficiency, in high power 550W and 650W models. We found Seasonic's OEM-version 80 Plus models to be everything that is claimed for them. Do these new Energy Plus models retain the strengths of the standard S12s while offering even higher efficiency?

80 Plus hits Retail: Silverstone's Element ST50EF-Plus

Power
80 Plus approved models are the most efficient of the efficient power supplies. 80 Plus certified power supplies are difficult to find on the retail market, however, because the program is aimed at system builders, not DIY enthusiasts. That's beginning to change. The Silverstone Element Plus is one of a handful 80 Plus power supplies now beginning to appear on the retail market.

Mushkin XP-650 power supply

Power
Is it memory or a power supply? The latter, from another memory brand wading into the crowded PSU market. The XP-650 has one of the most appealing packages this reviewer has seen for a power supply, and it is immaculately presented. Is there substance for quiet computing beneath the gleaming polished visage?

Enermax Noisetaker II (Rev. 2.2): A New Rev of an Old Fave

Power
Once upon a time, the Enermax NoiseTaker earned a recommendation from SPCR for being one of the quietest, most efficient power supplies ever. Then the NoiseTaker II was released, which got a less enthusiastic review about a year ago. Now, a new revision of the NoiseTaker II has been released. Can it reclaim the glory of the original version, or have times changed too much for SPCR to approve a dual fan power supply?

Tiny, Silent and Efficient: The picoPSU

Power
The tiny picoPSU is the most unconventional ATX12V power supply we've seen. By paying attention to how power supplies are actually used, not how they're specified, the creative guys at Mini-box have come up with an amazing tool for custom builders, silent PC enthusiasts, and SFF modders. It's not for everyone, but the picoPSU is right up our alley: Very efficient, innovative, and silent.

The ePower Tiger 550: Hot & Quiet

Power
Despite having well designed detachable cables, low noise at high power levels, and lots of glitz, the ePower Tiger fails to deliver when it counts. Electronically it's no more than an ordinary Tomcat, and it's cooled about as well as a polar bear in the Sahara. Sometimes, noise isn't all that counts...

Seasonic S12-330 PSU, new sleeved version

Power
The Seasonic S12 power supplies need no introduction. It's been a favorite on SPCR since its introduction a year ago. Now, it has been updated with longer, sleeved cables and lower capacity models boast a PCI Express connector. This time around we look at the baby of the bunch.

Antec SU380 power supply (in NSK2400 case)

Power
This power supply comes installed in the Antec NSK2400 media desktop case. At the time of writing, the SU380 can only be found in the NSK2400, and Antec appears to have no plans to make it available as a separately packaged retail product. It's quite a good PSU on all counts, but a bit noisier than the best.

Desktop CPU Power Survey, April 2006

CPUs|Motherboards | Power
It began as a follow-up to Turion 64 on the Desktop article, posted in mid-February. But then, the piece ballooned into something more ambitious, into an attempt to answer the question, "What is the best power efficiency achievable with current AMD and Intel processors that can be used on a desktop PC?" In the process, we ended up examining more than 15 processors in half a dozen family groups on six different test platforms, and took a stream of power measurements that kept our heads spinning for a couple of weeks. We have some answers. They comprise a snapshot of the fast-changing processor scene, taken from a particular angle, at this point in time.

Silentmaxx Fanless 400W MX460-PFL01 power supply

Power
Another addition to the fanless ranks looks very familiar. In fact, it's well nigh identical in appearance to the fanless Fortron Zen 300W PSU we reviewed last year. This one is branded with a different name and rated a hundred watts higher, with a bigger price tag. Is it still silent, and efficient enough to be 80 Plus?

Nexus NX-9003 350W Hybrid PSU

Power
Nexus, whose "Real Silent" fans have the right combination of low noise and wide distribution to make them a favorite among SPCR enthusiasts, has released a "hybrid" power supply. The word hybrid denotes a cross between fan-cooled and fanless: The cooling fan is designed to stay off most of the time, kicking in only when needed to cool things down to safe levels. It's not the first of its kind we've seen. We check to see how well the NX-9003 SFB works.

Enhance ENP-5136GH 360W PSU: A New 80 Plus Brand

Power
A new brand has made the 80 Plus approved high efficiency roster. We take the Enhance ENP-5136GH for a spin on our PSU testing rig and report some interesting findings.

SilverStone Strider ST56F power supply

Power
SilverStone is best known for their very nice aluminum PC cases and for their fanless power supply. They also happen to offer many other power supplies. The Strider is one of the quieter ones they offer -- other than the fanless one -- and still rated for 560W power delivery. How does the Strider fare on our demanding PSU test bench?
