But also take into consideration.... you arent using the full 850 watts. Watts = Volts x amps

Ohms Law

If you are in the US Volts is 120 on standard outlet

With the Amps i gave you.. At full load you are using 648 watts.

So you are looking at $43.55 per month.

The AC voltage at the wall doesn't matter, your computer's power supply converts that into lower voltage DC. As far as I know, a 12V rail supplies a lot of the power to a video card. So a good graphics card would probably pull over 25Amps at 12V DC. At the end of the day, that isn't something you need to worry about since computer equipment manufacturers report the maximum Wattage requirements to you. Those computer parts can then be paired with a power supply which is also simplified to watts in the "big label" literature. If you're building a computer it is good to know the amperage at each voltage, but it isn't a necessary consideration for this discussion.

Salain... Ok so lets think about this... If you have a power supply that puts out 850 Watts Max right... You still with me? And one video card = 25 amps...and we known ohms law thats been around for hundred of years is ..... to determine the amount of watts a device uses is. Watts = volts x amps

You still with me Bra...? 120volts x 25 amp = 3000 Watts = Salain is an idiot ! Go on Newegg and find me a powersupply that puts out 3000 watts and maybe will have a valid argument. " What a LAMA"
