Corsair HX450W

MSRP -- Released November, 2008

Pros

all the power that is required by the majority of people
can power any single carded gaming machine with ease
modular cables

Cons

will probably get louder faster than the 520/620 models (but with peoples loud video card, cpu and case fans this probably isn't a problem for the majority)
very little different than the value series (only modular cables and multiple 12V rails)

Cons

not modular
3 year warranty falls short of the 5 year offered for the vx450w ($15 more)
might not be powerful enough to support a video card that requires an 8-pin PCI-E power connection (possibly misleading)
