No display comming when powering on the PSU
I got the new PSU and new motherboard. Connected J8 to the motherboard ON/OFF switch. Pluged in the m2 atx 20pin to the mother. I am using car battery to test whether every thing is fine. I connect the J3 and J1 to the +ve terminal of the battery and J4 to -ve terminal.
After 5 sec delay, I can see the light in the motherboard and the light in the mouse comes and goes in a fraction, there is no display comming nor the lights on the keyoard comes up.
As I am new to this not sure what has gone wrong, need assist on this.
