Hey, 3, bought a 6850 graphics card, video card rated power of 120 watts, with a 400 Watt power supply, a little worried about power, 400W power and computer, how many hours an hour?
The power consumption of the computer = the actual output power of the power / the conversion efficiency of the power supply = the sum of the total power consumption of the parts / the efficiency of the conversion of the power supply
Theoretically, 400W power consumption is 0.4 degrees per hour.The power consumption of 1000 watts is one hour. Abbreviation kilowatt hour (degree).But the nominal power 400W, in fact, the power consumption is a certain fluctuation.
Ha ha, power is power, for example, the power is a bucket, and the computer CPU motherboard, video card is water. Video card 120W, CPU estimates, now 35W -45W (previously my AMD7750 90W), memory, hard disk power is very small, the motherboard is not large, the display is generally 35-45W speakers to count, video cards accounted for the general ah!
