I recently switched my PC case and now it won't start at all. The only thing that happens is the motherboard LEDs light up. I believe I've connected all components to the motherboard correctly, but I'm not sure what's going wrong. Here are my specs:
- Case: Empire Gaming Darkwitcher
- Motherboard: Asus TUF Gaming Mark 2 X299
- CPU: Intel i7 7740X
- GPU: AMD R9 280
- RAM: Kingston HyperX FURY 16GB 2666MHz DDR4
- Cooling: Antec Kuhler H2O 920
- WiFi+Bluetooth: Ziyituod AX210S
- PSU: Antec High Current Gamer 900W
I've also uploaded some photos and a video of the inside of my PC here: https://imgur.com/a/4Bh4SoJ

The orange LED next to the standby LEDs suggests that there may be a power issue. Check your power connections and make sure everything is secured properly.
Have you double-checked if the front panel connectors are properly installed? It's a common issue when building or swapping cases—sometimes they can be connected wrong and cause the PC not to power on.
It sounds like it might be the power supply if you're only seeing the motherboard LEDs. Are any fans spinning? If not, the PSU might not be sending power to all the components.
