The f14lab review demonstrates high load on 12v and low load on minor deviating the 12v rail by .367v, not great performance by any stretch of the imagination, and these results are consistent with other reviews.
OPP of the unit doesn't even work properly, in Computerbase DE's testing, when OPP kicked in the 12v rail was as low as 8.7v.
So what is certain, the GB Bronze platform flops during protection tests, and cross-load testing it flops (which is expected for a group regulated units). Whilst other performance is decent, the previous two issues make it an instant no-buy for me.
EDIT:
More Seasonic GB Bronze platforms failing: https://www.techpowerup.com/review/antec-hcg-620/7.html
This time, the 5v rail goes out of spec on high minor rail load. High 12v rail with low minor gives a near -0,4 voltage deviation. It also fails during transient response tests.
I'd hate to be the one to say that x reviews are invalid, but generally the reviews that feature protections testing tend to have more weight. Because a unit can perform fine, but lacking certain protections, or those protections not working is a deal-killer.
