I have everything in my case right now, except for a CPU, and RAM, and I have everything plugged in properly (or so I believe) however when I hit the power button my front fan lights up for half a second then turns off and nothing else happens. Is this normal considering I don't have a CPU in? The reason I feel I did something wrong is because I have two 6-pin connectors coming from the PSU and another 2-pin connector and they aren't plugged into anything so I'm worried I missed something. I think the 6 pin connectors might be for a graphics card that needs power that doesn't come from the motherboard. (I have an RX 560) Thanks in advance
