Why not include a small battery in the desktop computer to prevent sudden power outages?
For example, a small battery is built into a PC case, which only needs to last for the time of saving data after power failure. In theory, when used on a desktop computer, it is more than enough for temporary data storage. Just switch directly to battery powered mode like a laptop when the power is cut off. In the past, there really were ATX power supplies with backup batteries, all of which were commercial brands. Search engines can also find some old soft articles, such as “Oriental Pearl TV Tower Two in One Power Supply”, which didn’t sell much in those years and soon won’t sell. But it’s difficult to find similar physical objects now.
There are several reasons why the built-in battery power-off function in the chassis has been phased out:
1. The output power is not enough. If there is a built-in power supply, the first problem is that the power of the PC is very high. Desktop computers with high configurations can easily exceed 500W of power. Ordinary batteries cannot support such a large load, and switching to high-end batteries will inevitably increase the cost.
2. Battery life, this function can only be used a few times a year. How much does the battery lose after being fully charged for a year? The high temperature environment inside the chassis also has a significant impact on the battery, and continuous high temperature seriously affects the battery life.
3. Battery life: After a power outage, a small battery can last for a shorter period of time,
4. The built-in battery will become a bottleneck in the lifespan of desktop computers, and the reliability will be greatly reduced after long-term operation. It is uncertain which one will be disconnected first, AC or DC.
5. This type of power supply is much more expensive than normal, the rated power is not easy to increase, the battery capacity is only enough for about 5 minutes of use, and due to its complexity and high failure rate, the battery life is short.
This power supply also needs to supply power to the monitor, which exacerbates the battery pressure. In fact, this thing can only be used to prevent brief power outages during grid switching for a few seconds
The built-in battery power-off function in the computer case may be quite useless on desktop computers. Home users find it too low and expensive, while industry users find its functionality too weak. So it’s better to leave it to a professional UPS, as UPS has a longer lifespan, stronger maintainability, and better reliability.
How to prevent data loss on desktop computers during sudden power outages? If it is an important data computer, a professional backup power system such as UPS is generally chosen to ensure the normal operation of the business. For personal use, some micro UPS can be selected, such as APC’s UPS BK650-CH, which looks like a chubby socket overall. Depending on the model, it can provide a load of 300-500 watts and 5-10 minutes of use time. It is small in size and reliable in quality.
