hi guys, as all of u know the power situation of india and the power cuts , ive been thinking about running my PC on invertor. actually been doin that occasionally for an hour or so. but i want to know what is the exact power draw of my pc in KW hours. been searchin the net and the forum but couldnt find anything concrete in this matter. now afaik .. this isnt as simple as addding the specified wattages of different components . so anyone with knowhow or who has already experimented can jst lemme know. here are my system specs. i have a 22" lcd 2233SW (known to draw around 40 W but i use it at like 50 percent brightness and contrast) a iton 600va ups, creative 2.1 speakers a wifi router (with wifi permanently switched off) e5200 processor (not overclocked) biostar p43 a7 mobo 4gb ram palit 9600 GT cooler master extreme power 390 Watt (known to be 70 percent efficent) segate 7200.12 500gb hdd one combo drive one cooling fan 80mm and the usual keyboard and mouse. so what do u think would be the typical power consumption for this pc like when watching a movie?
