    I don't know man. Once beaten, twice shy. Even with the fixes, this is not a PSU that I will use or recommend. To me, the worst part is how Gigabyte tried to shrug off responsibility for the explosive PSU that are potential fire hazard, and put off fixing the shortcomings of the PSU for almost a year.
