Yes it will, but moving to that voltage for most means moving it in your kitchen or laundry room.  But the old psu ver. 1 and 2 suck d!c4.  Only viable option is the apw3-12 until J4bberwok gets his working solution.  We want a psu that fits in the case not outside.  Mine will be sent back to Denver, this time just the psu so there's no funny business.  I will demand this new psu since they seem to replace warrantied psu's with used stock.
