Power Ethernet PE Socket integrated Powerline Ethernet into wall socket

Power Ethernet reveals the PE Socket, a new Powerline networking product that has been integrated directly into an electrical socket. The PE Socket features one power socket and four Ethernet network ports in a single wall outlet. The product is currently only available in the UK, and pricing is pretty high at �144.

British technology start-up, Power Ethernet, has launched the �PE Socket�, the first product to integrate Powerline networking technology directly into an electrical socket. The PE Socket provides a simple and professional way of specifying high-speed data network connectivity throughout a building by using electrical cabling. The �PE Socket� is available from leading electrical resellers including CPC and Rapid Electronics.Based on the HomePlug AV standard for Powerline networking, Power Ethernet�s all-in-one PE Socket combines four Ethernet network ports, a fully-managed network switch and filtered power socket into a single device. It fits a UK Standard 35mm double gang metal back box and uses a building�s electrical wiring to create a high-speed and secure data network for connecting computers, Voice over IP phones, Internet-connected TVs and digital signage, home automation and entertainment systems, building management systems, CCTV cameras and other Ethernet connected-devices.

Power Ethernet�s PE Socket is unique in integrating Powerline into the electrical fabric of a building and its sockets. It�s a professionally engineered, reliable Powerline solution which has been aesthetically designed to ensure that the sockets can be installed in the most prominent of positions. This enables the creation of a high speed network without the need and the disruption of running specialised cabling.

In Greenfield sites, the Power Ethernet system removes the cost of specifying and installing additional cabling to provide network connectivity. In Brownfield sites, it also removes the costs of making good the installation of additional data cabling and reduces disruption by using existing electrical cabling. It can be used as a complete, backbone network for residential buildings, providing Internet and data connectivity for devices and home automation systems. In commercial buildings it can be used as a simple way of extending existing networks to accommodate demand for new device connections or creating sub-networks to support deployments of IP-based phones, CCTV cameras, building management systems or digital signage.

Power Ethernet managing director, Daniel Rogoff said: �Powerline offers such a simple and cost-effective solution to the challenge of connecting the growing number of Internet-enabled devices used in homes and businesses. However, we quickly realised that Powerline needed a professional makeover for it to reach its full potential as a networking technology. By integrating Powerline directly into the electrical fabric of a building, with the PE Socket, we are able to offer a reliable, simple and elegant approach to specifying Powerline networking. Best of all the PE Socket is designed to be installed by electricians without them having to learn data networking skills.�

The Power Ethernet socket supports speeds of up to 200Mbps across mains cabling and distances of up to 300 metres between sockets. The filtered power socket is designed to reduce the effect of electrically noisy devices that may be plugged into it in order to provide the highest network rates across the Powerline network.

Installing two or more PE Sockets instantly creates a high speed, secure Ethernet network running across the existing electrical mains cabling. More devices and additional rooms can be easily added to the network simply by installing additional PE Sockets so creating a truly flexible, affordable networking solution.

A Power Ethernet network includes the advanced networking features needed for commercial deployments, such as support for voice and video over IP, security (128 bit AES), device prioritisation (Quality of Service) and network segmentation (virtual LANs). With a fully-managed network switch on each socket, the Power Ethernet system integrates easily with existing enterprise networks.

Jou Jye BW-B620JL 620W Power Supply Review

Introduction

One of the perks of doing reviews on computer parts and peripherals is that you not only get to work with some of the best names in the industry, but also often get to work with companies who haven't yet made a name for themselves in one way or another. Today we are dealing with the latter in that most of our readers aren't going to have heard of Jou Jye Computer before. This is mostly because the company is known more in the OEM world and is slowly starting to push into the consumer world.

The unit that we are taking a look at today is the BW-B620JL power supply. It is a 620W power supply rated for Bronze level efficiency. The unit has a great list of connectors and 100% Japanese capacitor construction, however that isn't what has us intrigued the most. The unit has the ability to be linked directly with other power supplies from the same line and thus increase the total wattage of your system by running dual power supplies with ease...or more. Let's take a look and see what the BW-B620JL has to offer and just how well it performs.

Specifications, Availability and Pricing

Taking a look at the paper specs of the BW-B620JL power supply, we find that there are dual 12V rails capable of 24A each, with a combined total output of 48A. Both of the minor rails are capable of the same 24A each, but they have a combined maximum output of 130W. Add in the -12V and 5VSB rails and you have a combined total output of 620W. This certainly is far from powering a quad GPU system, but when linked it could be very close to doing so.

As we can see from the feature summary, there are a few things lacking from the Jou Jye unit. The two big ones are the over temperature protection and lack of being rated for 100% continuous output at 50C. The unit also lacks modular cables, but that is often a personal preference more than anything. It does feature over voltage/power/current protection, cable sleeving and is 80Plus Bronze certified.

Those in the US are going to play hell trying to get their hands on the BW-B620JL at the moment. Jou Jye is currently working on bringing the unit to the US and as such, there isn't any pricing information available either. The unit can be found with some digging in the UK for about �80. This works out to be about $125 USD, so it certainly isn't cheap by any means. By comparison, the last 620W PSU we looked at was the Antec HCG-620 and it had an MSRP of $79.99. There was no mention of warranty from Jou Jye either.

Corsair AX1200 1200W Power Supply Review

Introduction

Six years ago, loading a true enthusiast machine down with all the hardware you could muster meant that you were pulling no more than 600W-700W, and finding a power supply to handle that kind of load was nearly impossible. Since then we've seen a huge change in the hardware that enthusiasts utilize in their rigs. SLI brought about multi-GPU systems that required more power than ever.

We've seen a switch from using a single desktop processor overclocked to the max to dual processors with multiple cores� still overclocked to the max. Let's not even get into everything else that has evolved inside the computer. All of this is great, if you have the power to feed all of it. These days you'll need a minimum of 1000W to power a high end enthusiast machine - maybe even more.

While you have your selection of vendors for motherboards, memory, storage, and more, finding a power supply to fit the bill of such a machine produces few options. The last 12-18 months have brought some more selections, such as the Corsair Professional Series AX1200 that we are taking a look at today. The AX1200 is Corsair's flagship power supply. It is the biggest, meanest beast that they offer.

This PSU boasts an 80Plus Gold rating, has enough connections and power available to run two or three "normal" computers, and has a whole lot of other features to go with it. What matters most of course, is how the AX1200 performs. Nobody wants their rig shutting down in the middle of intensive use when it is needed most. Keep reading to find out all about the Corsair AX1200 and how it performs.

VIA Launches New Low Power QuadCore Nano CPU

VIA introduced its dual-core Nano just four months ago, but the company is already demonstrating that processor's big brother. The newly minted VIA QuadCore is--you guessed it--a quad-core processor that connects two dual-core Nano cores in an MCM (multi-chip module). The new chip won't actually ship for some months, but it may become a higher-performance alternative to both Atom and Brazos when it does...

Upgrade Power Supplies in Computers

type="html">

 

Power supplies are needed because your computer needs different voltages than what comes straight from the outlet. Disconnecting and replacing a power supply is simple because it's just piece of hardware.

1). Shut down your computer and unplug the cable from the wall and the back of your computer. Open the computer case. This may involve unscrewing the access door from the back of the computer, pushing a lever or just sliding the door off.

2). Unplug the power connectors from all of the drives and the motherboard. The connectors can be removed by either pulling them straight out or by pushing a release button first and then pulling the connector out. Some motherboards have two sockets where the power supply is plugged in.

3). Unscrew the power supply from the back of the case. The power supply is usually held in place by four Phillips screws. Pull the power supply out from inside the case. There is often a small shelf the power supply sits on. Hold on to the power supply as you unscrew it to make sure it doesn't fall.

4). Slide the new power supply into place. Screw it into the case from the back of the computer.

5). Connect all of the drives back to the power supply with the appropriate connectors. Connect the correct connectors to your motherboard as well. Make sure you plug the connectors back in the same direction they were plugged in as there is only one way in which they fit properly.

6). Close the computer case and plug the computer power cable into the power supply and the wall outlet.

Enable Power Management in the BIOS

type="html">

 

The BIOS controls the basic functioning of the various input/output devices connected or integrated within the system. Without the BIOS, the computer's main processor would not have the ability to communicate with or operate other pertinent components of the system. Enabling and adjusting the power management settings within the BIOS reduces power consumption and gives you control regarding how the computer operates when not in use.

1). Turn the computer on and enter the BIOS menu. Depending upon your particular computer or BIOS version, you have to press a certain key to gain access to the BIOS menu. Pay close attention to the display screen during the startup process, to determine the correct key. Alternately, consult your user manual or see Resources for a link of key combinations by manufacturer.

2). Enter the system password, if applicable.

3). Navigate to the appropriate power management options, using your keyboard. In most cases, highlighting a specific power management item produces an expanded explanation of the option.

4). Enable or adjust the appropriate power-management options, according to your needs. Save the settings and exit the BIOS menu. After saving and exiting the BIOS menu, the computer restarts.

What Does a Uninterruptible Power Supply Do

type="html">

An uninterruptible power supplies (UPS) serves as essential electrical backup to ensure that critical equipment stays running during power failures. When power is lost, the UPS automatically switches to its battery. Any electrical or electronic devices plugged into the UPS continue to work without a problem.

Voltage Monitor

Electronic circuits in the UPS continually monitor the power line's voltage. Normally, the alternating current (AC) power runs at 110 to 120 volts. If the voltage sags more than a few percent, for even a few thousandths of a second, the UPS switches over to battery power. The switching action is so fast that even sensitive equipment never registers a problem. When the AC line voltage returns to normal, the UPS switches the battery off, providing power straight from the outlet. The UPS uses the battery only when needed.

DC to AC Conversion

The electric power available at a standard outlet is alternating current, or AC. This electricity reverses direction at 60 cycles per second. Any appliance plugged into an outlet needs AC at the correct voltage. The UPS's battery produces direct current (DC) at a much lower voltage. An electronic circuit called an inverter converts the DC battery power to 120-volt AC that appliances can use.

Alarm

The UPS sounds an audible alarm when the power goes out, indicating that it's running on battery power. Depending on the size of the UPS and the devices running on it, the battery can last anywhere from 5 minutes to several hours. If you have a smaller UPS unit running a computer, for example, this gives you enough time to save your files and shut your computer down in an orderly fashion so you don't lose your work.

Surge Protection

In addition to battery backup, a UPS removes electrical surges from the power line from lightning and other causes. These spikes last millionths of a second but can damage sensitive electronic equipment such as computers. Your UPS may have separate sockets for surge protection. These sockets do not provide the advantage of battery backup, but will protect less-critical devices from power surges.

Battery Charger

During a power outage, the battery drains as the UPS uses its electricity. When the utility restores the power, the UPS automatically recharges the battery. If several outages take place within a short time, the UPS may exhaust the battery and shut down. But as long as power stays on for an extended period, the UPS will fully recharge the battery.

How to Change a Power LED

type="html">

 Many power supplies have an LED attached to indicate whether the device is powered on. Although LEDs rarely "burn out," they might need to be replaced if physically damaged by a blow. Owners of customized PCs might want to replace an LED with another of a different color to better fit the aesthetics of their design. Replacing an LED is usually straightforward, requiring one to unmount the old LED, disconnect it from its power supply, then solder and mount a replacement.

1). Disconnect the computer from the wall outlet and unplug all peripheral devices.

2). Touch a metal doorknob or other grounded bare metal surface to discharge any static electricity accumulated in your body. The electronic components in a computer are highly sensitive to static electricity and could be damaged by any buildup in your body.

3). Open the computer by unscrewing the case and slipping it off.

4). Unmount the old LED from the case. The exact method will vary depending on the specific model of computer case that you have. Some models hold the LED in place with small clips; others use glue.

5). Clip the power supply wires connected to the old LED with wirecutters. Try to do this as close to the old LED as convenient, to preserve ample wire for connecting the new LED.

6). Solder the new LED to the power supply wires. Make sure the wires' polarity and the LED's polarity matches. The negative wire is generally black, but this can vary by model. Consult your motherboard's manual if in doubt.

7). Mount the new LED in the case. Depending on what kind of case you have, you may need to use clips or glue.

8). Screw the case back on and power the machine up. Check the LED to make sure it lights.
