For information on performing the calculations see the section entitled "Power Predictions Before Adding Components" on Page 12 of this white paper. Example 2: Effects of Adding Memory Memory operates on the 3V channel, so if a 64MB DIMM is added it will only affect power consumption on the 3V channel. At this time, few components operate on the 3V channel so this addition will not adversely affect power consumption. Primary concern should be placed on the 5V and 12V channels. Example 3: Effects of Adding a CD-ROM Drive A CD-ROM drive consumes power on the 5V and 12V channel. When typical load is applied the CD-ROM drive will consume .7 amps on the 5V channel and .21 amps on the 12V channel. If one CD-ROM drive is added to a server it will consume an additional 3.5 watts on the 5V channel and 2.52 watts on the 12V channel.

increase power consumption on the 5V channel by 9.2 watts.
Adding two controllers will increase the power consumed on the 5V
channel by 18.4 watts.
For information on performing the calculations see the section entitled “Power Predictions Before Adding
Components” on Page 12 of this white paper.
Example 2: Effects of Adding Memory
Memory operates on the 3V channel, so if a 64MB DIMM is added it will only affect power consumption on the 3V channel.
At this time,
few components operate on the 3V channel so this addition will not adversely affect power consumption.
Primary concern should be
placed on the 5V and 12V channels.
Example 3: Effects of Adding a CD-ROM Drive
A CD-ROM drive consumes power on the 5V and 12V channel.
When typical load is applied the CD-ROM drive will consume .7 amps on
the 5V channel and .21 amps on the 12V channel.
If one CD-ROM drive is added to a server it will consume an additional 3.5 watts on
the 5V channel and 2.52 watts on the 12V channel. For information on performing the calculations see the section entitled “Power
Predictions Before Adding Components” on Page 12 of this white paper.
