SilverStone ST30NF Fanless ATX12V PSU

Power
The SilverStone ST30NF is probably the most sophisticated fanless PSU we've examined thus far. It weighs 6 lbs, uses a heatpipe cooling system, has twin LEDs for operational and temperature status, Active PFC, and even looks really slick. Rated at just 250W (for 120VAC input) but priced at US$159. Hmmm...

Antec NeoPower 480 PSU

Power
Antec has named a new power supply after pop cinema culture's most recent futuristic savior icon. The Antec NeoPower 480 is the first retail PSU with detachable, customizable peripheral output cables. Very nifty! It is also Antec's first 120mm fan model, with Active PFC and ATX12V V2.0 compliance for PCI Express. You can't help ask, Is it The One?

Coolmax Taurus CF-300 Fanless ATX PSU

Power
The Coolmax Taurus CF-300 is the second fanless ATX power supply to be reviewed by SPCR. Fanless cooling is the ultimate goal for those who pursue silent computing, and the Coolmax Taurus is one of the many new components that boast fanless operation. It is quiet and hihgly efficient but runs hot, and the review sample had a small malfunction. Nonetheless, a product worthy of consideration and a nice option for those who run cooler components in cooler climes.

OCZ Power Stream 470

Power
OCZ leaps into the PSU market with their new Power Stream series, which boast high power (420, 470 and 520W), low speed dual fan push-pull cooling, user adjustable voltage lines, EPS12V and SATA compatibility, and much bling in the form of mirrored chrome finish and LED fans. Is it suitable for high power quiet computing? We review the OCZ Power Stream OCZ470ADJ to bring you the full details.

Seasonic Super Series Revisited - Rev. A3

Power
The latest A3 Revision of the Super Series is Seasonic's attempt to fix intermittent fan controller problems that have dogged the previous revisions of these PSUs. Last week I received a package of four Rev. 03 Super series samples: One each of Super Tornado 300 and 400, and Super Silencer 300 and 400. Our revisit shows that not only has the fan controller been fixed, Seasonic also managed to make big improvements that might even justify the launch of a new line.

Chill Innovation CP-350A PSU

Power
The name Chill Innovation came up in in the SPCR forums, with some European members suggesting a close look at this 350W 120mm fan PSU. Not long thereafter, there came a promotional e-mail from Chill Innovation; naturally I responded with a request for a sample. That sample recently arrived, and now we have another PSU review for you to consider.

Zalman ZM400B PSU

Power
The Zalman ZM400B-APS is a solid ATX12V v1.3 compliant PSU that is very quiet at lower power levels. The current capability of the 12V line is high enough to handle all but the most loaded systems, the high >75% efficiency ensures it stays reasonably cool throughout the power range, and it can handle the heat all the way to max power at 50 degrees C. Check out the complete review.

Enermax NoiseTaker 475 PSU

Power
Frankly, the performance of this new NoiseTaker PSU from Enermax, whose products I have shunned for a couple years, surprises the heck out of me. Why? How about the highest efficiency I've ever measured, and the highest power output before the fan ramps up beyond idle? Is it the new ATX12V V1.3 compliant circuit they designed? Or the dual 12V rails? It's not clear, but one thing is for sure: This Enermax deserves a place in our Recommended PSU roster. Read the review for details. It's the first done with our new Thermal Simulation Case.

SPCR's Revised PSU Testing System

Power
It's a brief article about SPCR's PSU Testing System as it evolves forward. A new thermal simulation box provides a realistic working environment for the PSU under test, and a soon-to-come lab-grade Variable AC Power Supply will allow thorough examination of output power capabilty under real world stress conditions. Both new tools are better investigative tools for more precise results.

Nexus NX3500 120mm PSU

Power
Nexus has had some big PSU successes with quiet PC seekers. They have a new 120mm fan 350W model. What have Nexus done this time? Our sponsor EndPCNoise sent us a sample of the Nexus NX3500 "Real Silent PSU" 350W Special Edition so we could find out in a comprehensive review.

Seasonic Super Tornado 300 ATX12V v1.3 PSU

Power
The Seasonic Super Tornado 300 is the subject of a SPCR review. The Tornado is one of the new Super family of high efficiency power supplies by Seasonic to which the previously reviewed Super Silencer 400 also belongs. How does the Tornado fare? Well, we have a new fan-cooled quiet PSU king. Here also is Mikhailtech's review on the SS Tornado 300. He likes it a lot too: "The Super Tornado is one of the best power supplies I have had the pleasure of testing... recommend it without reservations."

Fortron FSP350-60PN "Aurora" 120mm fan PSU

Power
The Fortron-Source Aurora 350W ATX12V FSP350-60PN / LED Fan / non-PFC is the first 120mm fan power supply to be reviewed by SPCR. With its cool blue LED fan and nickel-plated exterior, it's one that's meant to be seen but not heard -- well not heard much, anyway.

Seasonic Super Silencer 400 - ATX12V 1.3

Power

It's evolutionary, but its performance is such that it almost seems revolutionary: A true 78% efficient PSU with Active PFC from Seasonic with extras at a relatively modest $99. ATX12V v1.3 compliant, cool and quiet in real applications, and very powerful. The Seasonic Super Silencer 400 looks like a winner from every angle.

proSilence PCS-350 Fanless PSU

Power
Fanless operation is the Holy Grail of silent computing: The proSilence PCS-350W is the first fanless drop-in substitute for a ATX12V Power Supply. It is not a product for everyone, but in the right PC configuration, this PSU gets you one step closer to the fanless ideal.

Nexus NX-4000 PSU

Power
The follow-up to its successful NX-3000 power supply is a higher power 400W model called... the NX-4000! We put the Nexus NX-4000 PSU through the grinder in SPCR's torture chamber and find out if it stays mum (quiet) and strong (stable).
