Can you please tell me the minimum power supply required for operate a GA-H57-USB3 motherboard with core i3 (530) processor. This information is not provided on the Gigabyte website. I am trying to install it in an Antec fusion case with 350W power supply and although the processor fan starts, the system will not post and does not even beep. I have sent the board and processor back to the supplier and they claim all is working fine in their tests. The only other variable is the power supply. I have not installed any other devices on the motherboard, no dedicated graphics card, no PCI devices, no hard drive. Any ideas please?
Many thanks,
Michael
