Hi
Is this the AJC card?

http://access1.sun.com/certify/reports/25/ASUS/ASUS-MOTHERBOARD_P54NP4D_PCI-I_P-100.html

Add-in Board Vendor:    AJC
  Model :               POWER CARD 5V TO 3.3V
  Board Type:           Other
   Type:                Single I/O
   Located in slot num: 4
   Bus Type:            PCI

Is it possible to convert PC AT Power Supply Unit  to PC ATX using this card?
Who is AJC? What is their address?
Thx.
