Hi,

we are planning to have zero client implementation (desktop virtualization) in place of current traditional desktops. To calculate actual ROI figures i want to calculate power being consumed by each desktop (apart of Monitor, keyboard and mice) i searched on dell and other manufactures website and found that figure somewhere at 200 Watts but desktops goes to sleep mode/stand by when not in use so i just wanted to know how much power a desktop used during sleep mode/power saving mode.

It'll depend on a number of factors -
the specification of the PC (processor), number of memory strips, accesory cards installed, what power saving features have been enabled (disks stopped, processor clock speed, accessories (network cards etc) "put to sleep"), monitor power saving enabled etc.

A PC put to sleep will still be drawing 30 - 40 watts (even with disks spun down). Monitors tend to comsume very little when in sleep mode (<5watts).

consider disk stop in sleep mode only.
move monitor consumption out of scope since its same with both solution (traditional desktop\Virualize desktop)

Get one of these

You can then monitor the computer while it is working and sleeping and get accurate figures rather than using the manufacturer's estimates.
