Im using a standard PSU over sized but thats what i had in hand EVGA 1300 with 8 Epower 450w juice box they have 4 PCIe connector each and run smoothly
Those box sells for 29$ each on Neweggs.canada
and 24$ on neweggs.usa
The main power supply is used to power the relay inside the juice box so it could be an El cheapo PSU with molex or just a custom wiring that brings 12v to the Juice box connector
Note: S1 @ stock clock 180ghs
Enjoy the info.
Thanks for the info. That might be just the thing for the S3 since they require 4 pci-e plugs. How are you getting all of them to turn on with just one psu?
