this would be a better option, it's better to have the 12v amperage over one powerful rail then over multiple rails.

this would even be fine for your gtx275's

For the most part Cm psu's are not that great, i think it was only the real power pro that were decent psu's.

I have the Cooler Master 1250 Real Power Pro and it's been good to me for close to 2 years now. For your system both of those you have linked should work good if you get a good one

I would rather go for something with a larger combined 12v amperage, because there is more chance of it overloading on the rails when the amperage supplied is not enough, although this probably won't happen, i think it depends on how the psu mechanics are designed, the source all the 12v rails are from.
