The +12V rail's OCP level is set rather low, while the minor rails have high OCP triggering points (as usual). The 5VSB rail should be set more conservatively; with close to 4.8A current output, its ripple suppression goes wild.

Over-power protection is set low as well, mostly because of the +12V rail's low OCP level. And OTP is set a little high, since this is a semi-passive PSU.

Unfortunately, the power-good signal is inaccurate.

    More RGB? *yawn* And is this usefully better in any way in terms of performance, etc. than the old 1275W XT Gold?
