It depends on the specifics of your system configuration and intended usage.
Upgrading the video card has typically been the biggest consideration in PSU
power requirements. At one point in the recent past video card power
requirements jumped from the <20watt range up to potentially over 60watts
for some high end models. Video cards without a secondary power connector
can't draw more than the bus limitation, something around 40watts IIRC.

My P4 Media Center (Radeon x600 PCIe video) came with a 350watt PSU.
Internally it is still the stock configuration (1Gig Ram, 300Gig SATA, DVD
burner and DVDrom yada yada) With a USB wireless adapter added and external
USB harddrive running the idle load on the UPS is less than 170Watts.
Without the external drive or monitor running, the idle load from just the
computer, wireless KB-Mouse, IR controller and USB WiFi is only between 112
and 125 watts. Turning on the webcam bumps that up another 20 watts or so.
Even with a second external drive connected I haven't had the system do
anything that ever drove the average power load above 250 watts for more
than a few moments.

.... thanks for that :-)
....and I always seem to keep half an eye on my old threads :-)
....built the thing now but, it's just sat there looking pretty and doing
nothing, I now have to try and move over to it, if you see what I mean !
....I ended up putting a Seasonic 430w S12 in it, when most probably the
380watt would have done, ...still it's pretty, and black ...and I suppose I
could take the cover off the case now and again and look at it !

best regards, Richard
