Will you pick power? Must first see these

When Xiao Bian recently designed an order for the little friends or answered the question of the breakdown, it was found that many people did not have enough understanding of the power supply, or there were always some misunderstandings, such as only concerned with the power (wattage), or particularly superstitious Some of these indicators, and some more, also hope to save money on power supplies. Therefore, Xiao Bian decided to specifically mention some of the things to select the power supply here, and see what indicators we should care about in the end.

Power: Peak is not equal to rated

When many small partners buy power, they see power 600W. But take a closer look. Is this figure the peak power or the rated power? The two are different. The former is the maximum output power that can be provided by the power supply in a short time, and the latter is the power to maintain stable output for a long time. Obviously, we should pay attention to the latter figure instead of the former. If a power supply can't be marked with rated power, Xiaobian advises everyone not to choose .

Models with maximum power as a model and no rated power

Is the module power really good ?

Module power is actually a relatively new concept. It is also divided into half modules and full modules. The full module is all detachable, while the half module is fixed main board and auxiliary power supply connections (may also have a small number of fixed connections), other power supply connections can be removed.

Full module and half module power supply

If you want to make the chassis more tidy, module power is a good choice. Its biggest advantage is that it only needs to install the connection of the used equipment, so that the chassis is more tidy and the cooling efficiency is improved. In addition, the standardized modular interface allows everyone to obtain a longer connection distance, more interfaces, and updated interface adaptation through optional connection. Of course, from a price point of view, the power consumption of the half-modules is more cost-effective, and the average total module cost is more than 20% more than the average power supply.

What is the conversion efficiency ?

Power supply packaging often see gold, silver, bronze, 80 Plus words, in fact, these terms are representative of an indicator that is the power conversion efficiency, in fact, is the ratio of input power and output power, the higher the conversion efficiency The better. Only ultra-high-efficiency power supplies are usually expensive, so you must consider your actual capabilities. In general, a Bronze 80 Plus power supply is sufficient.

Can't ignore video card power

If it is a game player, the power of the video card power supply can not be ignored. Video card and motherboard, CPU, hard disk, etc. are used 12V output, some power supply will be marked 12V1, 12V2 two-way power supply, in general, 12V1 mainly provides motherboard power supply interface, 12V2 is for graphics cards, hard drives and other equipment, this can be more Clearly see the video card power supply capabilities, before the next single, you may wish to look at the nameplate label or specification in the bar.

These are the most basic power purchase suggestions. Many times we ignore it, but in fact a very high quality power supply has a very high durability that almost exceeds the life cycle of the computer, so don't deliberately install it. Reduce/ignore power budgets.
