can I test power on my mother board with just the cpu and psu installed?

[mitchelhighers1358]

I installed my cpu and motherboard, connected It to the psu and turned it on to see if it got power. All I got was a quick flash on the motherboards rgb light and it turned off.

You need RAM too. Basic configuration is motherboard, CPU, RAM, and power supply.

Most will beep/display a code if no display adapter is present (if applicable); but, the act of getting teh code tells you the board and CPU are at least somewhat working...

Which motherboard do you use?

Like said, a LED, debug code can light up, hard drives will spin up, fans too, optical drive can open and close. But this won't tell you anything about a correctly working motherboard, CPU or power supply. At least RAM, CPU with cooler, motherboard and a Psu is necessary
