...
Today we have the latest model from Enermax: the Infiniti series in its 650W version. The Infiniti series was introduced about a year ago and we saw early samples in Taipei at that time. We were surprised by the high efficiency of the Infiniti when we first had a chance to look at one, and now we finally can review a shipping retail unit. Enermax has also added another new technology with this PSU called CoolGuard.[/url]

...
Today, Seasonic remains a very odd company in many respects, and it is difficult to compare them with many of their competitors. The size of the market for Seasonic products doesn't seem to matter; the company seems unconcerned with expanding their production facilities to meet market demands. Instead, management focuses on things like the development of newer and better products, preferring quality to quantity. That doesn't mean Seasonic is small, however; they manufacture many high-end, well known brands like Antec, Corsair, and PC Power & Cooling to drop a few names.[/url]

As PC systems are demanding more and more power, the power supply manufacturers are reacting by releasing units rated for higher power output. We can all thank NVIDIA and ATI, among others, for this trend, as we have seen an escalation in ridiculously high demands for power supplies with the latest graphics chips. That this power is in most cases unnecessary should be clear to everyone who owns such a card or wants to buy one.[/url]

While we've reviewed many higher-end (and higher-cost) power supplies, we've neglected the lower power segment. We hope to address that omission with today's roundup of four units ranging from 400W to 450W. Not many manufacturers these days make units rated at less than 500W - especially if we're talking about high-quality power supplies. Seasonic - both on their own and as an OEM manufacturer - is one of the few companies that continue to supply this market segment. We recently tested Seasonic's 330W and 500W models and found they were more than capable of powering most decent systems. There are far more midrange and lower systems on the market than high-end systems, so we thought it prudent to look at several competing models from other companies.[/url]

We recently published a major roundup of several high-end power supplies. As stated previously, such power supplies are already more than what most people will need, but for those looking to push extreme overclocking to new levels you might still need more power. We have eight 1000W power supplies we're looking at today the aim to provide just that. It's no surprise that power supplies in this range typically use high quality components, and the prices are also quite high. We have units from well-known companies as well as companies that are less familiar to our US readers.[/url]

These days, it's not always simple to choose the ideal power supply unit for one's needs. Faced with a bewildering array of manufacturers, brands, models and wattage levels, casual buyers often judge by outward appearances, attractive prices, or nominal wattage ratings. However, seasoned hardware enthusiasts generally shop for a power supply that's earned a reputation for quality and reliability, with appropriate wattage and price as secondary considerations. The consequences of a badly-chosen power supply may include system instability, lockups, BSODs, hard-disk corruption, and even catastrophic power-supply failure which damages other components; it's not simply a case of, say, losing a few 3DMarks because one chose a stylish-looking video card that happened to have slow RAM. The power supply is fundamental to the rest of the computer, and merits as much care as any other hardware purchase.[/url]

...
The label shows PCP&C's general approach to power supplies. We see a single 12V rail, which according to Doug is the best solution for power supplies. We are still waiting for our 15 hard-drives to arrive, but we have talked with at least one AnandTech reader that successfully powered up 18 hard-drives with a single-rail Silencer 750W where all multi-rail power supplies failed. The 12V rail provides a total of 64A and consumes up to 768W of power. In fact, the peak power is around 840W solely on the 12V rail, and our unit was able to reach 967W peak power during the tests. The 3.3 and 5V rails are rather small with only 22A and 26A, but that shouldn't be a problem.[/url]

We saw the first prototypes of the Pro82+ and Modu82+ series at CES, and we eagerly awaited our samples since then. At the following CeBIT in March, Enermax showed these two new series again but still we waited for our samples. After returning from CeBIT, we finally found our batch of PSUs at our doorstep and we started testing right away.[/url]

Amacrox might be not a familiar name to everyone, but the company just expanded its business over in Europe and should soon spread to the US as well. Most people in the PSU market know that Amacrox is actually a brand of the FSP group, which is the third largest power supply manufacturer worldwide. With Amacrox, the people at FSP wanted to create a brand that is actually "hip", whereas FSP is the more conservative brand. We already tested the Freestyle 750W in one of our roundups last year and found it performed quite well… until it failed. That certainly mars the impression, so we're here to look at a different PSU to find out if Amacrox can convey their message better this time.[/url]

Not really...
