I just finished building my PC waiting on the RAM still. Everything works fans for case and the AIO cooler. Motherboard LEDS work too. But when I go to plug in my keyboard, mouse, mouse pad it doesn't give power. I also can't turn off my PC with the power button on the case is it because of RAM? No display either which is due to RAM I think? Can only fully turn off the PC with the power switch from the PSU
