We are looking for a couple of new servers and it seems power is a big factor in the price of a colo at the moment.
PC based system (as opposed to Apple MAC)
1u case with Rails
Less that 0.5 amp at all times, including boot time
& max utilisation
Processor(s) with as many cores & clock cycles as we can get with the available power
Target Minimum specification
2 x 250GB hot-swap hard disks, RAID1
IPMI 2.0 system monitoring
1 USB port
Basic integrated display adapter
Keyboard & mouse ports
Thanks for any advice...

Reason: To say thanks!
Putting in 4GB of RAM (Im assuming 4 x 1GB..?) and another HDD will increase power on boot, and that is what they will measure your power usage as, on boot, im guessing around 0.65 amps... possible / probably more.
Hope this helps
PS there is a new AMD dual core "BE" chip that has really low power consumption, might be worth looking at those.
We run Tyan systems with 3 drives + RAID card + AMD Dual Core (EE versions), with 2GB RAM and they draw <0.5A, I think around 0.35A from memory when lightly loaded, still <0.5A when loaded as I recall. I should add, that we generally try and use single platter drives and as few DIMMs as possible as well, to keep the power usage down. I think the largest single platter drive you can get at the moment is 250GB (which is fine for 90% of our customers).
I think you are possibly getting far too worried about this. We only get charged £3 per .1 of an amp for overage which isnt a lot really. However you would be scarificing a lot in terms of server spec if you worried about keeping it under .5. Note, an athlon dual core 5200+, 4gb ram, 4x 250gb drives for us draws 0.55 on boot and between 0.4 and 0.5 when in use.
