That's what the standard design does - you have one power regulator (the big black brick that says PULSE on it) that powers all chips in parallel and all chips get the same voltage.
If one chip dies the rest will continue working normally. If the chip that dies actually short-circuits the board the regulator will normally detect the short and just completely cut out power. So in that case the board will still not work, but at least it won't melt the rest of the chips. And with some luck you could insulate the bad chip and get the rest working.
Actually the big Pulse component is an inductor. The regulator is the small TI chip below it.
duh ... I over-edited my previous post ... it was supposed to say "next to the big black brick that says PULSE"
Actually it isn't visible on the last few screenshots as there is a copper heatsink on top of it. (it is visible on the pictures from the OP - e.g. https://megabigpower.com/images/h-card.jpg)
By the way - sometimes more heat is produced by the inductor (that Pulse one) than the actual regulator chip. So if you're going overboard with heatsinks anyways - do add one to it as well.
