fit-PC2i Measured Power
Posted: Wed Feb 22, 2012 9:53 pm
I couldn't find any solid numbers when I was researching, so I thought I would provide my measurements for anybody else who's interested.
System: fit-PC2i, 2GHz, 2GB, Wifi Diskless with Intel SSDSA2CT040G3K5 40GB SSD
Setup: Linux Mint 9 with fit-PC kernel, audio disabled in BIOS
"Idle" means terminal open, watching top, nothing going on
"Active" means I'm running an acquisition process that consumes about 90% of the CPU and is writing to disk at about 2.7MB/s
Current/Power measurements taken using the lab 12v power supply. Note that using the provided AC->DC converter will raise these numbers due to power supply inefficiencies.
Full Operating Config (USB keyboard, USB mouse, HDMI->DVI->1920x1080 LCD, at the Mint desktop, eth0 connected and active, wifi board powered but down (ifconfig wlan0 down))
Idle: 635mA (7.62W)
Active: 745mA (8.94W)
No keyboard, no mouse, no monitor, eth0 connected and active, wifi board powered but down (ifconfig wlan0 down)
Idle: 505mA (6.06W)
Active: 615mA (7.38W)
No keyboard, no mouse, no monitor, eth0 powered but down (ifconfig eth0 down), wifi board powered but down (ifconfig wlan0 down), communication through serial console
Idle: 455mA (5.46W)
Active: 560mA (6.72W)
No keyboard, no mouse, no monitor, SDIO disabled in BIOS, eth0 (PCIe) disabled in BIOS, wifi board powered but down (ifconfig wlan0 down), communication through serial console
Idle: 435mA (5.22W)
Active: 540mA (6.48W)
