Nah, i don't think its gonna cut it.
You're gonna run into problems especially if you OC your system and run lots of fans in there.

i beg to differ but yeah, you can alway try it and get a new one if need be, you'll be sure then.
At that time i would probably hope to have 30 rep and sell you my 650tx cheap

But he doesn't have an OCed quad. Since he's only running a dual core, he will need ~50-75W less. He will be just fine with the vx450. You are just fine with the vx550.
I would also like to know how you knew the vx450 wasn't cutting it and how you know your vx550 still only barely powers your current rig.

What gadgets were they? What where your results? How did you come to those conclusions?
I sound like a teacher.
Personally I wouldn't run your rig on the 450, I would rather have the 550. But under most situations, the 450 would probably be able to handle it. It takes a PSU load tester and a oscilloscope at the least to judge whether a PSU is able to handle a given load. Anything else and it is a useless exercise.
