Power supply is an integral part of computer equipment and has a huge impact on your computer. It is considered the most valuable component of any device and the most important component that can cause it. This article tells you what you need to pay attention to when purchasing a power supply.1.Determine the wattage you need.Use a power supply calculator web page or software to help determine your requirements. Even better is to find a review of a similar system that measures power consumption. As that consumption is measured at the wall, multiply by the review system’s power supplies efficiency to get the output. Don’t purchase a power supply just above your requirements unless you plan not to upgrade the system. Purchase a power supply that will take you through your next few upgrades.2.Determine the robustness of the power supply.How well does the power supply handle changes in current? Although not a guarantee, there’s a strong correlation between weight and quality: bigger components equate to a more tolerant, reliable power supply. If you don’t care about noise, an 80mm cooling fan in the traditional place on the rear of the power supply may offer better value.
3.Research which connectors you need.Higher-end models may only provide a 24-pin connector, and lower-end models may provide just a 20-pin connector. Typically, most Pentium 4 and Athlon 64 CPU-based motherboards will require a 20-pin ATX connector, while newer motherboards require a 24-pin ATX connector. Also, most power supply will have both a 4-pin and 8-pin auxiliary 12V connector for motherboards, and only high-end power supply will have one or more 6-pin PCI-E connectors for video cards.4.Check the number of rails.Just as your house’s fuse box includes both a large main breaker and a smaller circuit breaker per circuit to ensure the smaller-branch circuit wires do not overheat, high-capacity power supply divide their output into multiple “rails,” each with a smaller current limit. The relevant safety standard requires a 20A limit, which is quite generous, given that the wires are smaller than those used in your house to carry 15A. A cheaper alternative is to provide just enough rails to total the overall capacity, which makes it difficult to use all of a power supply’s capacity.
5.Look for power supply with high-efficiency ratings.And, ones rated under load temperatures, not room temperatures. Anything 80% and above is good. At 83%, approximately 17% of the wattage is lost as heat. Therefore, a power supply that may be advertised as a 500W power supply, will actually be drawing almost 600W at the wall. Efficiency drops over time and during the life of the power supply. A year-old power supply is most likely not capable of producing the same amount of energy it once did when it was new.6.Get a modular power supply.It will help eliminate extra wires to get in the way of cooling. Ignore the claims by PC Power & Cooling that modular cables create more resistance due to corrosion of contacts. The additional resistance is negligible.7.Compare the amperage of each voltage.A power supply wattage rating isn’t conducive to determining amperage at any specific voltage. All power supply will have a sticker with their rated amperage at each voltage level. This information should be provided when purchasing a power supply from an online vendor and visible on the unit’s retail box. Do not neglect the power of the importance of choosing a good power supply is one of the prerequisites for your more joyful work.

What causes laptop battery loss?
Unplug the socket with the laptop battery every time the laptop is fully charged, playing the game with the battery, the power brightness to open the largest, and so on a series of reasons will accelerate the battery life. Laptop battery is a consumable, its life expectancy is not as long as the user imagined, what is the normal value of laptop battery loss?
Laptop battery, most manufacturers only half a year warranty, coupled with the current machine nominal standby time a lot of water. Are calculated based on the lowest power consumption, normal use simply do not have such an ideal state.
In use, even if some “misuse” accidentally hurt the battery, even if there are problems with the new battery, the loss within six months, but less than 20%, the daily use of the overall standby time will not be significantly reduced. And many people do not often pay attention to the extent of the battery loss. Let’s take a look at the laptop battery loss is what causes.
Laptop battery loss common causes:
1, often charge and discharge;
2, the use of low-quality charger;
3, high temperature environment for a long time;
4, the use of batteries is connected to high-load peripherals, plug is not standardized;
5, the transition charge and discharge, the circuit is now protected, but occurs occasionally.
Bad habits lead to laptop battery loss:
1, on the use of some poor heat conductor notebook (such as bed towels, pillows);
2, not completely shut down into the bag, the laptop to work, fever, but the bag was unable to remove heat;
3, the degree of loss and contact with the media, whether the battery parts close to the heat situation, but it is undeniable that this behavior leads to abnormal battery loss is very high probability, and this use is also one of the habits.
laptop battery maintenance errors:
1, for the first time using the battery, the first three need to charge 12 hours?
A: Three full charge is the legacy of nickel-based batteries when the habit, and lithium battery does not matter. And it’s not 12 hours either. As long as the display is full you can pull out.
2, in order to prevent the memory effect, it is necessary to charge before using electricity?
A: The characteristics of lithium battery makes it possible to charge at any time, but because of excessive charge and discharge will result in decreased life expectancy;
3, insert the AC, the laptop battery should be taken to prevent repeated charge and discharge?
A: If you remove the battery, long-term use or not charging, the battery will be damaged. Now notebooks are smart charging. After the battery is full, it will automatically stop charging. .
Repeatedly discharging the laptop battery will speed up laptop battery depletion, but this process can not be avoided, it is still consumables, the user need not worry, if the battery is broken, you can also plug in the power adapter.

Laptop battery model, how to find
Each laptop battery has its own unique model, just as everyone has their own ID number, so it is important to buy a replacement battery that matches your computer model.The first thing you need to know is the brand and model number of your laptop .We know that sometimes it can be difficult to find the model number of your laptop and the battery. If you are not sure about this, do not try to order a replacement laptop battery without this information. There are a few places where you can find this information.

Cell phone battery secret, you really know?
In fact, a blog called outeccbattery inside the website details how the phone in the lithium battery is feeling “pressure mountain.” Like humans, long-term pressure can hurt battery life. Here’s what they summed up: Do not charge after fully charged According to the website, full of electricity unpredictable, such as the phone has been attached to the night charging, in the long run is not conducive to the phone battery. Once the phone reaches 100% power, it goes into trickle charge mode, keeping the cell full. The phone battery is actually under high pressure, which can damage the chemical composition. The outeccbattery website gives a wealth of scientific data to explain why, but it sums it up nicely: “Unplug it when it’s fully charged.” “It’s like relaxing muscles after strenuous exercise.” In fact, do not charge to 100% At least when you do not need to be full, do not be full. Outeccbattery website said, “lithium batteries do not need to be completely full, full is not a good thing.In fact, the best not to full, because high pressure will increase the phone battery burden,” the long run will be a loss of battery. This may seem a bit counterintuitive to our instincts, but in fact it’s good to have your phone plugged in as long as you have a chance. At any time to the phone connected to power Compared to the phone battery depleted and then recharge a few hours, at any time when there is electricity connected to the power supply, so the phone battery better. Charging is the best when 10% of the phone battery is consumed. But obviously this is not practical for most people, so whenever there is a chance, put the phone on the power. It is okay to plug in and out repeatedly one day. This not only allows the cell phone batteries to maintain the best performance for longer, but also to maintain adequate power throughout the day. In addition, nothing plugged in, you can let go of those power-hungry programs and games. Keep cool Cell phone battery is very sensitive, and even Apple’s own suggestion to remove the phone shell is not conducive to heat when charging. “If you notice that the phone gets hot while charging, remove the phone case immediately.” If you are in the sun, do not direct the phone. These are to protect the battery life.
