I'm really surprised people aren't asking what the AMPS on the PSU are. the AMPS always tell you exactly how much wattage you can run at any given time (with a little math). PSU efficiency is another factor. Instead you're asking brand names. Remember if you're components do combine to a little more than your PSU can handle at once it might not be a problem. you might not be using everything all at once.
ask yourself, are you going to be using the dvd drive, the bluray drive, maxing out the cpu/mobo, and maxing out the GPU's and putting load on all 5 hard drives at the same time?
I think the lowest/highest I've heard of a hard drive running under load was 5-10w. so 5 hard drives would equal anywhere from 25-50w. even if it was 15-20w a piece from PSU efficiency it would still only need a max of 100w from the PSU for all 5 hard drives.
the ati 3650 uses around 42w under max load.
now you've got ~450w left to play with...
I don't have the time, but keep adding up the wattage each component uses, look it up if you have to. look how many amps your PSU has (it should say it on the PSU itself). convert the wattage of all the components combined to AMPS (I think they have internet calculators). And voila...you now know how much your system uses and how much your PSU can handle.
