I'm running a TP480--newer version and I have not had a single problem to date. I checked all the O/P voltages with a calibrated DVM and found the +5v rail reading 5.00 and the +12v reading 11.92---well within tolerance. In addition I measured the vcore an one of the mosfets next to the cpu ( a word of caution if you try this, be very careful you don't short out adjacent pins, you will destroy your MB.) and it read exactly what core center reported it to be---imagine that. The issue I have is that the voltage setting in the bios does not yield the correct voltage as measured. Not a major problem just something to be aware of. As far as the TP480 is concerned, I can't complain about it.
