sigh, seems sapphire decided to let us down with the 12vhpwr connector. And worse, nothing was added for load balancing, making this a possible dumpster fire. The asrock taichi apparently also has this connector, now I want to see if they did something to actually load balance this connector. For the people wanting a 9070(xt) from sapphire: their other models are apparently using the regular connectors. And from a few comparison videos here and there, they seem to be doing quite nicely in terms of cooling and power.
