The power supply is one of the crucial elements that make up the wonder we call the personal computer. With its status as a crucial element, why then do we often overlook the PSU?
One valid answer is that the PSU is often included when purchasing a PC chassis. Another possibility is that we do not know how much power the individual components require. In this article I intend to clarify the latter.
The motherboard (20 to 60 watt)
In today's market we are spoiledfor choice when purchasing motherboards. The entry-leveldesktop motherboard consumes as little as 20 watts, add a couple of extra USB ports and the consumption could climb to 35 watts. When purchasing a gaming motherboard with multiple PCIe slots the need tops at 60 watt.
The processor (60 to 140 watt)
With the introduction of the https://mrelectric.com/ new multi core processors from Intel and AMD, power consumption peaks at 140 watt. In the table below I have listed some popular processor choices with the power requirements of each.
Core2Duo 8 series
Athlon II X2
Core2 Duo 9 series
Athlon II X3
Athlon II X4
Phenom II X2
Phenom II X3
Phenom II X6
RAM (3 to 6 wattper Dimm)
PC's use three different types of RAM; they are DDR, DDR2and DDR3. DRRstill requires the most with 6 watts followed by DDR2with 4 watts Electrician Service and lastly DDR3requiring a mere 3 watts per Dimm.
Graphics Card (50 to 300 watt)
The graphics card is Best Electrician Service often considered the most power-hungrypart and to deduce its consumption level we will have to take a closer look at the power connectors present on the device.
Below is a guideline about what you can expect:
PCIe with no separate connectors 75 watts
PCIewith one 6Pin connector 150 watts
PCIewith 2x 6Pinconnectors/ PCIewith a 8Pin connector 225 watts
PCIewith a 8Pinand 6Pin connector 300 watts
Miscellaneous components (Find breakdown below)
Just add these components below up to tally your watt usage:
Case Fan 5 watts
Optical Drive 10 watts
Hard Drive 10 to 15 watts
Lighting (Refer to ballast)
When purchasing a new PSU make sure to leave some tolerance for expansion.
That concludes your PC's power consumption breakdown.
