I am attempting my first computer build and having problems. I have everything installed and I THOUGHT I had all the wiring/cabling done that I needed. But I can not get powered up. When I check the power supply with the EVGA supplied tester that covers up the MB end of the cable, it powers up and I feel the fan blowing. But when I actually connect it to the motherboard and flip the switch on, nothing happens. To make matters worse, I accidentally disconnected the wires leading from the front panel to the rest of the system and I'm not sure I got them all back where they need to be. I have an Enthoo Luxe case and the wiring seems to be slightly different than what I would expect. Can you please help me? Tell me where to start looking for issues, from the most basic things forward. Any and all help is appreciated.
