Computers Tips : How to Choose an Uninterruptible Power Supply

When choosing an uninterruptible power supply, or UPS, determine how much energy is needed to run the computer and find a UPS with a battery that will store enough energy to accommodate the computer during a power failure. Find out the equation used to determine energy usage for computers, fax machines or telephones with information from a computer technician in this free video on computers.

How can i find out how mutch Watt my pc uses ?? thanks if u answer =)

[sabasania]

hey ...... i need a very inexpensive UPS or any other setup just to power my ADSL router, that works on DC input of 5V and 1A, and currently i am connecting with an adapter that gives me that output, but itself needs 100-240 Volts, u can suggest some device 1) that i can connect my adapter into .....or.. 2) something that replaces the adapter, and i connect directly my modem directly to it.

Is there a way I can find out how many watts my computer has I need to know cuz I'm upgrading my processor the one I have right now is 65 watts the new one is 95 watts plz some one help

[syncmaster710n14]

This information is helpful but what I hant to know is how long a supply will last. you see ware I live we get alot of 10-20min power outages so i want a ups that will last about 30min. It will only be runing a small server about 500 watts.

@motonegros umm yes

I believe this guy is wrong.The energy the computer uses is always less than the PSU.For example if you had a 450watt psu your computer would use when everything would be working in it's max power about 400-420 watts.The component tha uses most power is the GPU,the only way you could reach 400-420 watts would be if you were playing a hardcore game,having your GPU,HDD,RAM memory and every component working in it's max level,which for a simple user would never probably happen

sirmasterpimp ......you stated " allows the battery to be discharged down to 20% without causing damage. If you discharge a normal car battery to 50% it will be permanently damaged ".........the UPS battery is as you said. The discharge rates are ALL the same - down to 10.5 volts 3 times will kill an ordinary car battery......a UPS battery has thicker plates and the glass fiber so can be " hammered " a lot harder and still keep going. Kill 3 times rate then battery is dead does not apply

[sirmasterpimp]

@arshedhussainkadir A car battery is a flooded lead acid battery filled with battery acid (about a gallon of it) and is loaded with lots of thin lead plates. A 12 volt ups battery also uses acid, but keeps it between a glass mat (like fiber glass). The glass mat allows the battery to be discharged down to 20% without causing damage. If you discharge a normal car battery to 50% it will be permanently damaged. The ups battery is similar to deep cycle agm batteries used in rv's, boats and car audio
