I'm about to begin building a new PC, but first I need to check if my CPU (Intel Core I5 12400 - stepping H0 (S-Spec SRL5Y)) is supported by my motherboard (MSI B660M Mortar Wifi DDR4). MSI support page says that stepping H0 is only supported with bios v12. Thus I need to check whether the factory installed bios will support my CPU. So I just want to install the CPU into the motherboard and check if it posts into the bios (without connecting any heatsink, peripherals, fans, memory etc). I'm guessing I need to connect the power supply cables of ATX_PWR1 and CPU_PWR1 /CPU_PWR2. But are there any other cables I need to connect ? I will connect the motherboard to a monitor with an HDMI cable (CPU has onboard GPU so should hopefully work). Thanks
