Surface Book 2 can’t stay charged during gaming sessions
The Surface Book 2 is aimed at graphic pros, but with a stout NVIDIA 1060 GPU, it's a tempting gaming machine, too. As we observed during our review, gaming drains the battery pretty fast, though. Worse, The Verge noticed that the power supply can't actually charge the battery fast enough to prevent it from draining in some cases. A Microsoft spokesman has confirmed to The Verge that "in some intense, prolonged gaming scenarios with Power Mode Slider set to 'best performance' the battery may discharge while connected to the power supply."
Single-charger standard proposed for laptops to reduce e-waste, frustration
The group that successfully pushed for a common smartphone charging-connection (in Europe) now has its sights on a bigger target: laptops. The International Electrotechnical Commission (IEC) recently proposed mandating power supply compatibility across manufacturers and models as a way to reduce e-waste. While the idea of one charger to rule them all sounds rad, the IEC is quick to temper our excitement, saying that due to technical realities, this initiative is still likely a long way from being achievable. Sadly, it looks like the days of replacing entire computers because the power brick was discontinued aren't over just yet. [Image credit: Ian Sane/Flickr]
Intel Haswell's idle states reportedly won't play well with some power supplies
One of the staples of Intel's upcoming Haswell processor architecture is its support for lower-power idle states that can rival tablet chips in power consumption, even on the desktop. However, that may come with a big caveat for budget and custom-built PCs: certain power supplies might not cut it. VR-Zone claims that those idle states require as little as 0.05 amps of current, which could be too nuanced for older or cut-rate supplies that deliver power in bigger clumps. That might not be a problem for companies building complete PCs, but Corsair's Robert Pearce tells The Tech Report that it may lead to a lot of motherboard builders playing it safe by disabling those specific modes by default. Many of us, in turn, would either have to buy a fresh supply or toggle the power-saving options ourselves. We've reached out to Intel to verify the truth, but it may be wisest to make a cleaner break from the past with any near-term upgrades.
Rohm 5Wh hydrogen fuel cells power up smartphones, ready for the trash after one charge
Rohm's hydrogen fuel cells are meant to power smartphones and other mobile devices, but unlike other juicing-up solutions, the cells are only good for one charge. Rohm says disposable fuel cells can be made smaller and lighter than their multi-use counterparts, and as the only byproduct is hydrogen, the company is touting the cells' eco-friendliness. The system generates electricity by using hydrogen that's created by the reaction of a metal material and water. While the device we saw here at CEATEC is a prototype, Rohm may offer its recharging system as both a smartphone case and a USB-attachable juicepack. Each offers 5Wh and can fully charge a handset once. There's also a 200W power generator, which certainly stretches the meaning of portable but can keep a laptop, LCD TV and a peripheral or two going for three to four hours. Rohm says its fuel cells will see a commercial release some time in 2013; for now you can get a sneak peek in our hands-on gallery below. Zach Honig contributed to this report.
New fuel cell keeps on going even once the fuel's dried up
Vanadium oxide seems to be the go-to guy in power storage right now. A new solid-oxide fuel cell -- developed at Harvard's School of Engineering and Applied Sciences -- that can also store energy like a battery, also uses the stuff. In the new cell, by adding a VOx layer it allows the SOFC to both generate and store power. Example applications would be situations where a lightweight power source is required, with the potential to provide reserve juice should the main fuel source run out. The team who developed the cell usually work with platinum-based SOFCs, but they can't store a charge for much more than 15 seconds. By adding the VOx, this proof of concept extended that by 14 times, with the potential for more lifespan with further development. Especially handy if you're always running out of sugar.
AMD announces 900MHz version of the Radeon HD 7750, calls it 'the other 7750'
The original Radeon HD 7750 won plaudits for its low-wattage performance and $109 price tag, but now AMD's decided to put out an additional version with 100MHz more clock whizz. The new card also happens to be called the Radeon HD 7750, and it'll sit alongside its doppelganger on the shelves of the world's computer stores just daring you spot the difference. How will you do that? By checking if it requires a separate power supply: the original 7750 was powered entirely through the PCIe slot, limiting its power to 75W and hence its clock speed to 800MHz, while the new one accepts additional power to deliver slightly more grunt and stay ahead of looming competition from NVIDIA. XFX has already jumped aboard with the 7750 Black Edition Double Dissipation priced at $115 after a rebate, and AnandTech says other vendors will follow suit. So, unless you're totally out of power jacks, you know what to look for. Image courtesy of Newegg.
GAEMS announces new Sentry Xbox 360 suitcase, teases Project Vanguard
How could we forget the GAEMS personal gaming environment? Looking something like a cross between a laptop from the eighties, and a bomb disposal unit, the all-in-one Xbox system was always going to make an impression. Well, with E3 just around the corner, it looks like there might be another model on the way. All we know at the moment is that it's called "Sentry," and will have more of a personal entertainment leaning. This being based on the fact that on top of the Xbox gaming, GAMES only went as far to tease that services like Netflix, HULU and YouTube will be increasingly central to it. The firm is also revealing a new device with the working title "Project Vanguard," about which it's even more secretive. Either way, better make more room on that luggage rack.
Sandia Labs develops self monitoring smart outlet, still needs you to plug it in
The folk at Sandia Labs work on all sorts of interesting projects, and the latest thing to fan our utopian dreams is this experimental smart power outlet. Unlike most monitoring set-ups, it can measure and control electric load without being connected to a central management system. The outlet comprises four receptacles, each with voltage and current sensors and a small computer which shuttles data over an Ethernet bridge. This autonomous style of operation could lead to more intelligent power grids that self-monitor, adapt and integrate with other grids without complex infrastructure updates. Other benefits include removing large points of failure, desirable in any network, and simpler home power monitoring systems. Sandia Labs' prototype could also improve effectiveness of variable output energy sources such as wind and solar, thanks to its ability to compensate for flux in energy production -- which might come in handy.
Cooler Master launches Silent Pro Hybrid Fanless Series of power supplies
Desktop PC power supplies are tough to get excited about, no matter how many features they cram in. But Cooler Master's Silent Pro Hybrid Fanless series is actually pretty alluring. The supply isn't actually "fanless" but it does have a fanless mode that can be used to minimize machine noise, at least until the load crosses the 200W threshold. Add to that a 90-percent efficiency, fully modular cables and a control panel that lets you manually adjust the speed of your system fans and you're looking at quite the compelling product for the DIY desktop enthusiast. As you could have guessed though, all these fancy features don't come cheap. Cooler Master is offering three different models: 850W, 1050W and 1300W, which range in price from $200 to $300 -- a sizable chunk of change to drop on any component. They'll be shipping this month to the US and Asia, with Europe to follow in November. Check out the complete PR after the break.
GAEMS Xbox 360 traveling case gets sleek redesign, still won't help you spell correctly
The last rendition we saw of the GAEMS console-carrying case looked more like a giant lunch box than a solution to your portable gaming needs. If you're still interested in bringing your Xbox 360 on the road, the company has redesigned the case and it now supports the fat and slim versions of the 360 and even the PS3-skinny. What's new in this compact carrying case is the fact there's actually room to store the console, controllers and power brick. It comes bundled with a remote, HDMI cable and power supply to power the speakers and LED screen. If you're road trippin' any time soon and want this beast, you can save yourself 20 bones by pre-ordering before April 20th and you'll receive the $300 case come June.
OCZ intros Vertex 3 Pro, Vertex 3 EX and Z-Drive R3 PCIe SSD at CES
Hello, speedsters! OCZ Technology has just busted out a new trio of solid state solutions here at CES, so we won't waste any time getting down to business. Up first is the performance-oriented, MLC-based Vertex 3 Pro, which runs along quite hastily on the SATA 6Gbps interface. We're told that it's built with a next-generation SandForce controller, enabling it to approach 80,000 IOPS and demonstrate 550MB/sec transfer rates. Up next is the Vertex 3 EX, which also utilizes a SATA 6Gbps interface but relies on SLC Flash memory. It's also capable of pushing a similar read rate (and the write rate of 525MB/sec ain't too shabby, either), with both the EX and Pro to be offered in capacities of 50GB, 100GB, 200GB and 400GB. Finally, the third-generation Z-Drive is being officially revealed, with the Z-Drive "R3" PCI Express SSD being the company's first SandForce-drive PCIe SSD. It's engineered for Tier-0/1 data applications, and offers performance rates of 1GB/sec and 135,000 IOPS. Those with absurdly deep pockets can buy one with up to 1.2TB of onboard storage, but alas, OCZ's not serving up MSRPs on any of these guys. The full release is after the break, complete with details on its new ZX Series of power supplies. %Gallery-112480%
Oval bookshelf is the perfect case for this DIY car stereo radio (video)
Got a leftover head unit sitting about? How about a PC power supply? Add a few old speakers, a oval bookshelf, a sewing machine box handle and some carefully prepared wooden panels, and you've got a beautiful retro radio that looks like several hundred bucks. User iminthebathroom built this one for a daughter's Christmas present, but isn't keeping the formula to him or herself -- you'll find a full walkthrough at Instructables if you're in a MacGuyver mood, and a video after the break to show you what the cherry-red contraption can do.
APC adds LCD, zero-draw power outlets to new Back-UPS Pro models
A new uninterruptible power supply isn't exactly the sort of thing to garner a ton of attention, but APC's latest Back-UPS Pro models do pack a few more features than your average power supply, and may just have you considering trading up. They're still just as uninterruptible as ever, of course, but the BR1300G and BR1500G models add a snazzy new LCD that displays the estimated runtime and other critical information, as well as some new power-saving outlets that will automatically shut off power to any unused devices. Otherwise, you can expect runtimes of between 92 and 164 minutes (depending on what's connected, of course), six or ten power outlets, and APC's usual PowerChute software for some more enhanced power management. Still no firm word on a release date for these, but they should be available sometime in the second quarter for between $129.99 and $249.99.
Ask Engadget HD: Best power and line conditioners for a big home theater?
Alright, this one will separate the serious home theater heads from the rest. While a dedicated mains and UPS may be the way to go for some, a need for clean power distribution should make James' question a consideration for any high end setup: "What do you recommend for power and line conditioners for large home theater systems? Monster units are the only ones I'm familiar with, but i know they're not the most liked company around these parts. Suggestions?" James, we hear you. You need a solution where better cabling might provide actual benefit and don't want to finance next weeks crush-the-little-guy lawsuit, we've all been there. We haven't covered a lot of power conditioners around these parts so why don't you let him know what's providing controlled AC to your system?
Ultra sues just about every other modular power supply manufacturer
Ultra Products, Inc. is trying its hand at that most glorious of corporate traditions: suing the pants off one's competition. The maker of computer components is taking 22 -- yes, twenty two! -- of their competitors to court, claiming to have a patent for modular power supplies since November of 2006. Ultra says they sent several warnings to the companies about the violations and is asking for the legal maximum of three times the damages. The suit actually doesn't accuse the companies of violating the patent, but of being an accomplice to end users who are violating the patent. Oh, and unless we're missing something here, Hewlett Packard filed a modular power supply patent in 2000 -- we certainly recall Screen Savers covering the devices way back in '99.[Thanks, Mack]
Gigabyte's Visuals: the USB gauge for your PSU
We don't want you to get your hopes all sky high for nothin', so we'll preface this by noting that Gigabyte's Visuals only operates with the firm's Odin GT-series of power supplies. For those still with us, this monitor-mountable gizmo enables users to keep a close eye on the temperature, power and fan speed of their PSU, and it gets all the juice / information it needs via USB. Granted, it's probably overkill for all but the most hardcore of overclockers, but no one here ever said that extravagance was necessarily a bad thing. Look for this one to land anytime for a currently undisclosed price, and hey, maybe next year Gigabyte will open up the compatibility list a bit, eh?[Via OhGizmo]
Marvell chip claims to make PCs more energy efficient
Mark this down as a little out there, but a new Marvell chip claims to improve the efficiency of desktop and laptop power supplies by determining and then optimizing the amount of energy each particular application needs. Named a "power factor correction controller," the chip enables computers to comply with new Energy Star guidelines that require computers to use at least 80 percent of the energy supplied to power them. It's not the only chip out there that claims to improve efficiency using this method, although Marvell has already started producing the chips with the aim of hitting full volume production in Q1 2008, and seeing them in PCs thereafter.
Defense Department seeking a better wearable power supply
The US Defense Department is looking to lighten the load soldiers have to lug around in order to keep all their gear powered, and its hoping the general public can help them do it. To that end, the DoD's gone and busted out a DARPA-style competition, with a million dollars in prize money in store for the winner. They'll have their work cut out for them though, as the competition demands that the power supply be half the weight of current systems while still providing the same amount of power (or more). That translates to a system that weighs no more than 4 kilograms (8.8 pounds) and provides enough power for 96 hours of operation, with a peak power requirement of 200W for short periods. Even if you don't come out on top, you'll still have a shot at the $500,000 and $250,000 prizes for second and third place, although you'll have to get your act together pretty quickly: the cut-off date for registration is in November of this year, with the whole thing set to wrap up a year after that.[Via The Inquirer]
JSP Tech's 450-watt liquid-cooled power supply
These days, it's not difficult to find a cutting-edge hardware component with a liquid-cooled option, but streaming water through a power supply is a new one on us. Aside from the potential fire hazard implications, we're a bit stumped as to why a vanilla 450-watt power supply would actually need such superfluous cooling measures in place, but we can assume that this bad boy is whisper quiet until it springs a leak. Nevertheless, JSP Tech's interesting new PSU was spotted at Computex with a CPU cooling extension tackily attached to it, but we've no idea if or when this admittedly questionable device will ever hit the market.
Microsoft, Wal-Mart sued over baby's death
While the figurative jury is still out as to whether video games harm our youth by inciting them to commit violence, loiter unnecessarily, and utter profanities, a real flesh-and-blood jury may soon be deciding if one faulty Xbox was to blame for the December 2004 death of an Illinois baby. The family of young Wade Kline is suing Microsoft, retail giant Wal-Mart, and an unnamed power supply manufacturer in state court for damages "in excess of $50,000," claiming that their console -- the suit cites a 360, though it's more likely that the it was a first-gen unit sporting one of those recalled power cord -- overheated and caused the attached wall outlet to spark what turned out to be a fatal fire. This isn't the first time we've seen Xboxes and fire go to bed together, but it may be the first attempt to hold someone accountable for the damage done, so it'll be interesting to see how the culpability gets doled out here.
