The U.S. Patent and Trademark Office put to rest a three-year dispute between Ultra Products, now a part of the Streak Products division of Systemax, and several power supply makers by rejecting Ultra's claim regarding modular PSU design patents, Softpedia.com reports. The USPTO came to the conclusion after seeing examples of the technology being used in prior PSUs.
Do you have a difficult time trying to figure out what size power supply you'll need for your next build? With so many variables in play, it's no easy task, yet it's critical you get it right. Overshoot your power needs and you'll end up wasting money on a larger PSU than you need, potentially depriving funds from other parts of your build. But sell yourself short and instability could rear its ugly mug. The online eXtreme PSU Calculator is a great starting point and it's just been updated.
There's no mistaking the target audience for Corsair's new line of power supplies; it says so right on the box. Enthusiast Series TX V2, is the name of the new line, which is the successor to the original Enthusiast Series TX family. This time around, Corsair says you can expect more of the same -- like Japanese capacitors and a comprehensive fixed cable set -- as well as improved energy efficiency, 80PLUS Bronze certification, and lower noise levels.
OCZ's decision to exit the DRAM market means it can spend more time and resources on the rest of its product portfolio, and if the new ZX power supply series is any indication, OCZ made the right move. On paper, the ZX series is the most ambitious PSU line OCZ has yet released, and that's saying something for a company that owns PC Power & Cooling.
Geared towards enthusiasts, the lowest wattage ZX unit is a beefy 850W. If that's not enough, there's also a 1,000W model and a 1,250W unit to choose from. Despite all that power, all three remarkably received the coveted 80+ Gold Certification and offer 92 percent efficiency on a typical load and 89 percent at full bore.
Other features include a 140mm ball-bearing fan, a single +12V rail, and a fully-modular design which is a first for OCZ. No world on price or availability.
The eXtreme Power Supply Calculator is our online go-to source for better than quick-and-dirty estimates of how much power our proposed builds are going to pull, and the latest update adds a handful of new hardware.
Now included is support for AMD's new Radeon HD 6970 and 6950 videocards, as well as Nvidia's GeForce GTX 570 and GT 430 GPUs. On the CPU side, the PSU calculator now recognizes a bunch of new AMD Phenom II X6 processors, including the 1065T and 1100T, as well as a handful of other AMD chips.
The Lite version is still free to use, while the Pro version runs $1.99 and provides a few more details, such as +12V, +5V, and +3.3V rail breakdowns, recommended UPS ratings, and expanded multi-videocard support.
Long time readers of Maximum PC magazine already know what we think of PC Power & Cooling (now owned by OCZ). More than a couple of PCP&P power supplies have ended up in our annual Dream Machine builds, and for good reason -- the company typically puts out rock solid PSUs.
The latest entry to PCP&P's PSU line is the Silencer 760, hitting the sweet spot in the Silencer series that ranges from 500W to 910W. The 760W also "further raises the bar with an 80 PLUS Silver efficiency" rating, running at 88 percent efficiency on a typical load.
As with all PCP&P PSUs, the Silencer 760 pumps all of its +12V amps through a single rail (74A in this case) rather than split them up through two, three, or even four +12V rails, as some PSU makers are prone to do. Other features include 835W peak power (the 760W rating is continuous power), dual 6-pin PCI-E connectors, dual 6/8-pin PCI-E connectors, eight SATA connectors, seven peripheral connectors, and one mini connector.
Now in version 2.5, the latest eXtreme Power Supply Calculator update adds support for a bevy of new videocards, including the Nvidia GeForce GTX 580, AMD Radeon HD 6870, and HD 5850.
For you workstation gurus, the latest version now recognizes a whole bunch of professional videocards, including 20 new Nvidia Quadro cards and 19 new AMD FireGL, FirePro, and FireStream GPUs.
Other additions include an option for a mini-ITX motherboard and Intel Pentium D 935 and 945 Presler chips. The Lite version is free to use and lets you estimate what your system power requirements will look like, while the Pro version (prices range from $1.99/3 days to $9.99/lifetime) goes into a bit more detail with info on individual rails (+3.3V, +5V, and +12V), recommended UPS rating, and more.
Quick, what's the most important piece of the PC building puzzle? That depends on what you're trying to accomplish, of course, but some will contend that no matter what the task, the power supply stands as the one area you never want to skimp in. And they're right -- we've seen generic units pop, fizzle, and even smoke.
Antec, for the most part, has a long history of putting out reliable units (some of which were built by Seasonic), and the company hopes to have another winner on its hands with its new High Current Gamer series.
"The High Current Gamer series is designed to optimize high-output current delivery while reducing wiring loss, resulting in unsurpassable value and reliability in a package that provides affordability and accessibility to gamers and power users working within varying budgets," Antec says.
Available in 400W, 520W, 620W, 750W, and 900W configurations, Antec says each one features over-current protected +12V rails with High Current functionality. Each one also comes stamped with the 80 PLUS Bronze certification.
Without any fanfare or ballyhooing, XFX this week expanded its power supply lineup with its new Pro Series with "EasyRail Technology." What exactly is EasyRail Technology, you ask?
From what we gather, it's XFX's fancy way of saying the Pro Series utilizes a single, beefy +12V rail rather than spreading the available amperage out across multiple +12V rails.
The Pro Series is available in 650W, 750W, and 850W models, each of which is 80 PLUS Bronze certified, which means they run at 85 percent efficiency with a 50 percent load. They also look to be CrossFire and SLI certified with support for up to 3-way multi-GPU configurations, depending on the videocard, and sport fixed cables.
We've only spotted these in the UK for around $106 (650W), $115 (750W) and $130 (850W). No word on when these will ship Stateside.
If you've never used the eXtreme PSU Calculator before, give it a whirl the next time you're in the market for a power supply. The free version includes a ton of configuration options to give you a better than ballpark estimate on what size power supply your build will likely require.
Protip: Under system type, choose the number of physical CPUs you have, and not the number of cores. So if you're running a Phenom II X4 processor, you'll choose "1 physical CPU."
