How much power consumed in both S3 standby and Hibernate

[tlucca]

HI all,

Just wondering if anyone knows how many watts of power a computer uses both in S3 standby mode and in hibernate. Im debating leaving my computer on for faxes in S3 standby but I heard it could be over 100 watts of power if left in this mode.

I posted this in the "highly tech" forum, but figured Id post here too,

Any info on this would be greatly appreciated.

BYW, my system is:
Dell Dimension 8400 with Win XP MCE 2005
512 mb pc3200 ram
160 Gb HD
nvidia 6800 N/U 256mb vid
Soundblaster audigy 2
faxmodem
DVD +/- burner
DVD ROm

thanks,
Tom

In the Hibernate mode, the computer shuts off everything...you could even unplug your PC (to ensure that there's no power drawn) and move it around.. There's zero consumption.

In the S3 mode (Suspend to RAM), power is supplied from the SMPS to the RAM, etc. The SMPS supplies around 3A on the +5VSB power rail...So I guess the power consumption should be under 15W in S3 mode. You also need to factor in the PSU ineffiencies to convert AC-DC, which should be minor in the standby mode.
