Nine things to note when choosing a power supply

Now with the machine most people do not attach importance to the power of this thing, think as long as the power is enough, in fact, the power is one of the most critical components of the computer, is the security of computer stability, the following introduction to select the power to pay attention to the problem.

1, the power supply must have more than 250W rated power, preferably above 300W, to meet the current home Windows 7 mainstream configuration of power requirements;

2, power supply +12v output must reach more than 14A, preferably two-way +12v. This should be the current family mainstream platform stable operation of the standard logistics support, the current user for the use of Windows 7 special effects, the beginning of the graphics card in GEFORCE7300GT. And will be on the new configuration to hang their previous storage, I believe that the number will be more than 2;

3, Power DC output must have 24P main power interface, 4PIN processor power supply interface, more than 2 SATA interface, preferably with 6pin graphics power supply interface and 8PIN processor power supply interface. The power supply interface is a major factor in limiting future upgrades, so users who cannot one-step are best prepared to provide a broad posterior approach to their power supply.

4, to ensure that the line loss is small, the line diameter must be 18th or 16th. Most users will ignore the choice of the output wire itself, and will be in the wire to wrap the nylon net. However, the material and size of the wire determines the power output line resistance, so as to increase the share of the hardware in tandem with the voltage, on the one hand, the hardware supply voltage is insufficient, on the other hand, increase the heat on the wire, accelerate the aging of rubber, may eventually cause fire.

5, the power supply dynamic response speed quickly. When running large programs, the system power supply changes very large, instantaneous will produce very large current changes, if the voltage changes can not keep up with the current changes, Then the system may appear  dysentery ⑺ ⒒ suo  to recognize the frog U Wu Ping  enjoyed the harmonic sinewy of the Yie,, vinegar, sleet, vぃ⑶, and M to expand ㄓ not а"flurried ┟ 诖 Benedict  1 Leisure turn Wu ┎ fen  enjoyed ci harmonic ∩ lift porcelain times The happy  to change clenbuterol beard and death disaster is actually lame ⑿ Manchurian
