It's good to buy a regulated power supply!
-
Buy a general-purpose PC power supply, the input voltage specification is 85V-264V, with an active PFC circuit. ** More expensive, as little as four or five hundred, as much as six or seven hundred.

It depends mainly on your city.
BAI electrical voltage stability, and.
The type of UPS you need, if you only bring a computer, it is a backup, but the voltage stabilization effect of the backup type is not ideal. If the voltage is unstable there, you can add a wide switching power supply in front of the UPS, which can meet the requirements you need. There is also time to shut down after a power outage.
If you only need voltage regulation, you don't need to use UPS.

It seems to understand what you're asking.
Frequent power outages, with UPS
Often the voltage is low or fluctuates greatly, and a wide range switching power supply is used.
There were power outages and fluctuations, so I had to use them all.
-
UPS power supplies tend to be AC power supplies, while wide-range switching power supplies are DC power supplies, and the two cannot be compared
-
What the interracial spies are entangled in. Rule.
-
Hard shutdown, restart after a few minutes of power failure.
-
Don't press anything.
Wait a few minutes to watch.
-
It may be that the motherboard battery is dead, causing the CMOS settings to be lost, press F1 to enter the settings or F2 to skip.
-
The motherboard CMOS battery is dead, replace it!
-
Just reboot it.

Since it is clear that the computer reboot is caused by voltage instability, there are generally only two solutions regardless of software, system, power strip or anything: wide power supply or voltage regulator.
Voltage regulator: There is a certain reaction process, and there is basically no resistance to instantaneous ups and downs (such as caused by the start of the air conditioner), so the voltage regulator is suitable for continuous low pressure.
Wide power supply: It can adapt to the voltage change from about 140 volts to about 270 volts, and it works quickly.
Wide power supply is recommended for your situation.

According to your description, it should be caused by voltage instability, and it is recommended to buy a voltage regulator so that it will only be beneficial to the computer, about 200.
But I recommend checking the temperature of the computer before buying, because you say that it will only appear in summer, and it will not be restarted after the temperature is high.

Is it a notebook or?
Turn on the Wake-on-LAN function or set it in the Power Options.

Hehe, I was like that at the beginning. If you suddenly turn on the fluorescent lights in the middle of the night, the computer will automatically restart. At first, I was also puzzled, it would automatically restart, it was amazing.
I later sent it to the manufacturer for warranty, saying that it was a motherboard replacement for me, and now it's fine. It seemed that when the fluorescent lamp was activated, there was an instantaneous pulse or something, and he didn't make it clear. Changing the motherboard should do the trick.

You buy a new power strip and move all the computer sockets to that socket and try it, and it should be fine.
UPS power supply refers to an uninterruptible power supply, which is a system equipment that connects the battery to the host and converts direct current into mains power through module circuits such as the host inverter. It is mainly used to provide stable and uninterrupted power supply for a single computer, computer network system or other power electronic equipment such as solenoid valves and pressure transmitters. >>>More
The most straightforward difference.
1. There will be a conversion time of about 10 milliseconds for the backup UPS to be powered by UPS after a power failure (suitable for personal computers, PCs, terminals, etc.). >>>More
First of all, you must determine how much power your device is, generally speaking, the power of ordinary PC or industrial computer is about 200W, Mac is about 300W, and the server is between 300W and 600W. >>>More
If you talk about reasonableness, of course, it is an independent power supply and does not directly use a 12V battery ** each camera without UPS inverter. The unified power supply circuit is simple, but the cost of UPS is significantly higher due to the high power and battery life of UPS. I think the appropriate solution is to equip each camera with a 12V power supply according to the backup requirements and use a relay to supply power to it. >>>More
There are many kinds of PFC circuits, what you are talking about is only one of them, and it is also a relatively old one, through this modulated switching circuit, the current absorbed by the rectifier is the sine wave current, and it is synchronized with the voltage, and the function of PFC is realized. Another function of the DC DC boost chopper is to increase the voltage of the DC bus to meet the requirements of the peak output of AC current, so that the output of the UPS no longer needs a transformer. >>>More
