12V performance
We use a Chroma loader and test harness to assess the quality of the PSU, and it enables us to evaluate the various facets for a PSU's technical excellence. We retested an FSP Aurum Platinum-rated 1,200W and Corsair HX 1200i supply to provide meaningful comparisons against the Gigabyte. The trio have the same capacity and efficiency rating.
The supplies do just fine when loading the 12V line, well within the parameters set by the ATX spec. Gigabyte's variance is a little higher than the other two.
Cross-loads are harder for a PSU to deal with because voltage is being concurrently applied to different rails at one time. Think of it as loading up your CPU, graphics and peripherals all in one go - a worst-case scenario.
Cross-load 1 puts almost all of the capacity down the throat of the minor lines while stressing the 12V line(s) with a couple of amps. The reverse is true of cross-load 2.
Nothing untoward here.
