- can be undervolted to 10-11V to achieve even better efficiency - in the range of 900/360 (SP20 doesnt really get any better than 900/420). This requires uncommon 12-10V voltage regulators though and generally there's 5%+ losses in doing so

can you link to such experiments, where the gains of the S5 are higher than the losses of the DC2DC step down devices?

there is no such experiment posted.

once sidehack gets his build to work correctly it will be 95% so

10/12 is 83.33% divide by 95% = 87.71

so a 10 volt setting would use 87.71 percent of the normal watts. (not 83.33%)

as sidehack says he is close.

If he gets it to work this gear should allow newer designs to use it. like a psu it will move from generation to generation of miners.

It may influence asic design to be like the s-5 in string
