I still would not try it but I mean...look at it this way.
An overclocked Quad-Core to around 3.6ghz will take AT LEAST 200w's and then an overclocked 8800GTS depending can take 120+
300w/12=26.6amps needed on the 12's.
Thats just a rough estimate and actually quad-s take more than that. Not to mention that DVD drives and other things take amps.
You can try it but I wouldn't risk it. This is why I suggest at least 35 to be safe but you could get away with lower.

You do realize that the Enermax Liberty are high quality PSU's and the 550w model I believe has 34 amps...you have 8 more amps than his Thermaltake which is what is needed. Please don't tell him he is fine when he is clearly not.

Your Q6600 @ 1.35vcore (dunno how but very nice) is saving your *** with that PSU. 28A would normally as stated be impossible to run with a Q6600 running at 3.6ghz which the usual 1.5Vcore however its saving you 3 or 4 amps which keeps it at the bare minimum for you as well.
