Default Visiontek 800W @ KG

I have only one question: Are these voltage numbers real?

Most likely. Tweak Town got similar results on the Mushkin Joule 800w with their Fast Auto ATE.

The only big difference is the readings from Tweak Town are higher on the 12v, but the drop is similar (-0.15v @ TT & -0.18v @ KG)
5v & 3.3v are pretty much dead on between the two.
The only major difference between them is Tweak Town reporting 22mv of ripple while KG reported 50mv and KG actually had a 4A lighter load on the 12v side of things.

Though, that could have something to do with the caps. Those AsiaX guys are not consistent performers.

I don't believe such a group-regulated design can deliver good voltage in crossload tests.

That's a valid point, there's no precedent for that, from Aurum to S12IIB they've all crumbled when crossloaded.. those can't be the actual numbers for the crossload tests.

On second inspection, I give you that. Crossload numbers don't make sense for a group regulated unit. For instance, compare heavy +5V crossload and progressive test 1 - 12V is lower in the former, even though it has less load and +5V has tons of load, so theoretically 12V should skyrocket. I can believe in good voltages @12V heavy crossload (see S12II), but that would require sacrifices on 5V heavy crossload.
