I have read the sticky about the 300watt psus...but i'm still not sure what i need.
here is what i'm going to build.
antec super lanboy
9800XT w/ zm80c-hp
MSI K8t-Neo mobo
athlon64 3400+
1gb corsair pc4000 pro
2 x samsung hdd raid 0
1 x hitachi 7k250
plextor px-708
at first i was thinking of the fortron fsp-350 aurora....but then i wasn't sure if 350 on that psu was going to do the trick.
EDIT: i'm buliding this comp for a friend....money is almost no object....around 100 should be right
help w/ choosing a psu for high power system

I believe that the Athlon-64 will use the +12V for power.
This means that your load will be concentrated on the +12V.
A guesstimate would be: 90W CPU+30W GPU+20 W HDD+20 W Optical drive = 160W plus a few more watts for fans and possibly for future things.
Most good PSU's (including 300W) can handle 15A on +12V (~180W).
Knowing that 180W is close to what you will actually be using I would
consider looking at slightly more powerful units just to have some margin.
The FSP350W you mentiond handles 16A on +12V, and according to SPCR review it has very good stability on the voltage lines. I would say it does look like a fine choise.
