Cases & PSU/Power Supplies by piotke @ 2004-11-28

You notice that for the Yesico test setup another motherboard was used, however I connected both PSU’s to this system to verify that the results we got with MBM5 were correct and directly comparable.

  • 350 watt
  • +3.3 V - 20 A
  • +5 V - 30 A
  • +12 V - 16 A
  • +5 VSB - 3 A
