Can I use a desktop converter on a home?
I have a desktop computer and the PSU is Cooler Master 550W GX and its 550-watt power supply group. I wonder if I can operate my home computer on my UPS or not? My house UPS has a rating of about 700 watts. Also, I would like to know what a "modified sine inverter" and a "pure sine inverter" and how can I make a distinction between the two without using electrical control, etc.? In addition, will be running on a computer or other of the two types of damage UPS to the computer?
By definition, any inverter is a modified sine inverter. The non-sine wave modified as you see comes straight from a wall outlet. If you use something (anything) off of a battery voltage, which is product is an approximation of a sine wave (modified sine wave). If you pay extra for "Pure Sine Inverter," you are getting an inverter that claims to provide an output less modified, pure sine wave. How do you tell the difference between the two? Price would a huge indicator. WEIGHT would be another. The UPS that refines the modified sine wave would be more expensive and heavier. I do not think you damaging a computer by turning on an inverter. However, if you do, your UPS had better be evaluated at least three times the size of food computer. I would not recommend running a 550W power supply out of a meager 700W inverter. Although I do not think it would harm the computer. . . 700W UPS will not last long. It could fry immediately. Or if you're lucky you might get one or two months out of him. Whatever drive you buy will have to have thick cables, directly connected to the battery terminals. Personally, I would not feel comfortable running an office less than a 2000W inverter. But you may be able to get by with a good quality inverter range 1200-1500W. There is a better idea. For the money you need to pay for an appropriately sized, high quality inverter to power the Desktop computer power supply. . . You can save money by buying a cheapie UPS 200-400W (hardliner Sears, for example) and also purchase a small laptop or netbook cheap system. IMHO, save the desktop for home use where you can plug into a wall outlet (but use a good surge protector). Instead of spending hundreds of dollars on a UPS that can power the office, get yourself a laptop and a relatively cheap (but good quality) converter like this to run it: http://www.sears.com/shc/s/p_10153_12605_02871494000P? OR, be prepared to spend a buttload of money on a large, variable quality: http://www.amazon.com/gp/product/B00153EWLY
