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.
Intel
AMD
Core2Duo 8 series
65 watts
Athlon II X2
65 watts
Core2 Duo 9 series
95 watts
Athlon II X3
45 watts
Core2 Quad
95 watts
Athlon II X4
95 watts
Core i3
75 watts
Phenom II X2
80 watts
Core i5
95 watts
Phenom II X3
95 watts
Core i7
130 watt
Phenom II X6
140 watts
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.
