Look for reviews from the same reviewer. JG did not do a PCP&C so had to look at PCPer for a solid review done by both.
Corsair
PCP&C
Judging by the nice round results on the second review I am going to say they were only accurate to 5mv and those are probably identical in ripple.
checking out the first page of the review it looks like his test equipment has evolved over the 4 years since the PCP&C unit came out. Due to cap aging and such I would say the AX1200 would be better, but if you already have the turbo cool, than just use that.
