Thanks for that Paul.
My main concern is whether the included 200W PSU will be sufficient to
power a mid-range video card, Athlon 64 CPU, a SATA hard drive or two,
DVD burner etc.
There are some real power measurements for Athlon64 here. The
Winchester looks pretty good. You can use the real power
measurements to apply a correction to the takaman data below.

This site will allow you to calculate needed power.
http://takaman.jp/D/?english
Notes on Takaman data:
1) CPU estimates are based on TDP, which will be on the high side.
2) Memory powers are more reasonable than some other power supply
estimator sites. (Download some micron.com DDR datasheets to see
for yourself what real numbers are like.)
3) Listed disk drive power is for startup only (i.e. during motor
spinup). The +12V will drop to 0.5A or so, once the drive is
running at speed. The optical drive listed below is a
"power footprint" number (similar to a TDP) and is not
representative of real power, but I don't have any real numbers
to correct it. I tried looking one night for real optical drive
power numbers from ODD manufacturers, but couldn't find any.

OK. You have good reason to be concerned. The Asus supply
has 3.3@14 5@21 12@10 and +5VSB@2 . The +12V is pretty
weak, if you plan on using a video card like a FX5900.
If you use a video card without a separate drive cable,
expect video card power to drop to around 30W or so (about
half the power listed above).
For additional sanity testing, these xbitlabs articles have
real power measurements of some video cards. You can correct
the takaman numbers with the data in here.
