Power supply and UPS power supply is a big difference?
The voltage is mainly stabilized. Can not be charged. That is, when the power failure, the regulator will immediately power, can lead to data can not be saved in time, computer failure. The price is cheaper than UPS.
UPS, mainly a charge storage function. That is, when the power outage, UPS can use their own stored power to the computer power supply.

Regulated power supply is generally only rectifier regulator, UPS is the inverter output
Ups is: regulator, emergency power supply, power grid protection, can be extra battery, long delay models up to ten hours of emergency power supply capacity (very expensive oh) if dealing with important data, be sure to buy ups, pure online , Buy a little brand, such as Hills, apc. These ups regulator capacity is several times the regulator, you can also eliminate other hazards in the power grid, such as surge, clutter. If you do not often deal with important data, you can buy back ups, can save a lot of meters, at least you can hold on to shut down, so that a sudden power out of bad hard drive (hard disk high-speed read more easily bad,
