The Recommended Power Supply For A Quad Core

Quad core CPUs can give excellent performance despite their small size.


The recommended power supply wattage for a quad core processor should range from at least 400 watts to 500 watts, depending on the computer's use. The highest-draw quad core processors can use up to 130 watts of the computer's total power.


Other Components


The central processing unit (CPU) is not the biggest power consumer in many computers: that title belongs to the graphics card. Newer and slower-clocked quad core processors can use 65 watts or fewer, which can bring down the total need for power. However, the other components still use more power than the CPU. You can get away with a 400 watt supply if you have a lower-consuming CPU.


Consumption Exceptions


It is possible to get away with a 300 watt power supply if the computer will not be doing graphically intense work. Peak power consumption occurs when the CPU and graphics card are being pushed hard. Conversely, a graphics heavy computer may need more than 600 watts.


Average TDP


Computers very rarely -- if ever -- use 100 percent of the power supply's output, its thermal design power (TDP). It is recommended you use a power supply that can support 90 percent of the power needed by all computer parts. Therefore, a 130 watt CPU will use about117 watts under a very high load.
