Is it 600 watts or what? I have a media centre computer and I want to know what should be the power of an inverter if I want to attach one. This is because the power supply is uneven in my area. The power is 230 v not 110.

Here's a rough guide of how much watts a component will require to operate (when active, not in sleep mode) in a modern computer (at most 3 years-old):
Motherboard: About 25w
Mouse+Keyboard: 3w.
Processor: 55w to 100w (yes, 100 watts for the Prescotts).
Memory: About 10w per stick.
Videocard: 58w to 89w. SLI/XFire with overclocking require over ***200w***. Thus, there's 1000w certified PSUs now for desktops -- a must for high end SLI/XFire rigs.
Audiocard: 10w.
Hard Drive (per drive): About 25w.
DVD/CD Drive (per drive): Around 30 to 35w
Fans (per fan): 3w to 8w.
USB device (per plug in use): 3w
Firewire (per plug in use): 8w
Roughly: 244watts when in use (no overclocking). Overclocking requires more watts and amps.
So why suggest 600w PSUs? Because those PSUs have Active PFC (line conditioning to not fry hardware); better and beefier components to last longer and use less energy; larger heatsinks and capacitors to withstand 24/7 operation; emit less heat. And most importantly more 12+ and 12- amps to run the newer videocards. 18Amps on the 12 rails is least needed to run the latest videocards.
A computer won't use all 600w when it's on. It only uses what is needed (think of turning on and off the air conditioning. It's always ready to use, but it doesn't turn on unless a temperature is reached or you turn it on yourself). Being that the 600w class PSUs are so efficient, you'll wind up spending less on electricity with one, too. Also not heat up a room so badly in the summer.

600 watts is what the power supply is capable of supplying. It's not the wattage you computer is consuming.
Desktops - 100-200 watts (depends on activity)
LCD - 40 to 90 watts (72 watts for 20" LCD)
Wattage is the same for either voltage.

600 watts should be enough for a pc and lcd monitor. Note that a CRT moniter will use up to 200 watts while an LCD about a tenth of that

Power supplies, often referred to as "switching power supplies", use switcher technology to convert the AC input to lower DC voltages. The typical voltages supplied are:
* 3.3 volts
* 5 volts
* 12 volts
The 3.3- and 5-volts are typically used by digital circuits, while the 12-volt is used to run motors in disk drives and fans.

get a 600 VA ups
mostly available in 500 & 600 VA
> but i think u mean time factor too ?
if yes, lemme know ... gotta try differently

about as much as three 64 watt light bulbs

As far as io know,
min =430watt (less performance)
max = 500watt (better performance)

it differs from each computer, check with the manufacture.
