In basic OC'ing (I want to take a e6300 to 2.6-2.7), how important is your PSU?
I have an Antec True Power2.0 430 watt psu right now. One HD, one DVD drive, one videocard (X1600pro) and maybe a wireless PCI card.
 
A good stable PSU is the most important part of any computer, OC or not. Your current PSU should be rated for at least 20A on the 12V rail if you want to do any OCing - that's just a general rule of thumb, not a hard number. Your current PSU is good for around 13A on the 12V rail *if* you have the 3.3V and 5V rails fully loaded - chances are that's not going to happen, so you should be OK with what you have.
 
I also think you will be ok, I run all the stuff in my sig with a 420W supply but with a little more speced on the 12V

(PS next on shopping list tho, :D )
 
for a 2.7ghz overclock (psh, shoot for a 3.2) your PSU isn't that important.

Most PSU's can easily cope, while providing stable power to the line filters on the board, with the load of a single GPU system.

Most boards these days have 4-8 layers of power filtration, making a super stable PSU redundant.

An ample quality PSU, that can supply enough power under a real load condition (so 40c rather than the 25c manufacturer spec.) should be all that's needed for a CPU OC.

When you get into a high-end GPU setup, however, that typically have only 2-4 layers of power protection, a nice, powerful PSU is a good investment. Pulling 34a from a system designed to deliver only 36 is bad news, regardless of who makes it.

Bottom line, if you've got a passable PSU, that can supply enough power to your system, with a good reputation of not dying, you'll be fine. I've never seen an OC harmed with an under-powered psu, you just get a bit of instability, that's easily diagnosable during a stress test.
