no its not,

look at the crysis and furmark power draw charts, furmark puts the most strain onto a system, and even that is under the 400w of the psu.

this is the test system used,

from all the info i have seen around the net, a psu runs best at around 75%, so its fine.

the CX400 only has one pci-e connector, luckily there will be a molex to pci-e adaptor in the graphics card box.
 
Not really. Hard Drives use about 20W at Max and Case Fans use about 2-3W on average. Provided you have enough peripheral connectors (Molex) and Sata connectors you should be fine, unless you have dozens of drives and fans.
 
Just as a rough idea, the rig in my siggy plus 5x fans, Zalman ZM-MFC2 multifunction controller, Hdd, dvdrw pulls a peak of 320w at the wall and that's when running Furmark and Prime at the same time. Bearing in mind the cpu and gpu are overvolted and heavily clocked that's pretty low.
 
Did this yesterday with rig:

Done some power testing the other day with my power meter and see what my rig pulled from the mains:

615w with Prime & Fur Mark running
405w with Prime running
503w with Fur Mark running
272w Idle

Looks like that 480 draws a lot of power, even at idle. My fully laden system draws 450w with a 4890 and 155w at idle.
