undervolting on PSU level is indeed a point I missed before. Are there any DIY?
Or is efficiency directly degraded after modding?
we have a forum member that is well respected working on a plug in 'pot' type device.
plug in a plat psu at 12 volt and 92 % out comes an 87% 9 volt pcie jack.
since the power should reduce greatly that loss will be okay.
ie .52 drops to .32 .87 = .36
or you can buy this
http://megawatt.us/ which will go close to 9.5 volts but is 80% so .32 .8 = .4 per gh
this is all theory no one has demonstrated a s-5 running at 9-10 volts clocked to freq 225 or freq 250 to be stable.
