9 Solución de problemas
9.1. Power Supply Unit (PSU) Installation Difficulty
If you encounter difficulty installing the PSU, ensure that any removable metal side panels or brackets in the PSU shroud area are correctly positioned or removed as needed. Some designs may require specific orientation or temporary removal of parts to facilitate PSU placement.
9.2. PCI-E Bracket Removal
Some PCI-E slot covers may be designed to be broken off rather than screwed. If you find the brackets difficult to remove, carefully bend them back and forth until they detach. It is advisable to do this before installing the motherboard to avoid accidental damage.
9.3. Fan Control and RGB Synchronization
If the RGB fans are not functioning as expected or you wish to synchronize them with your motherboard's RGB software, ensure the fan controller is correctly connected to both the power supply and the motherboard's D-RGB header (if available and compatible). Refer to your motherboard manual for specific D-RGB header locations and software instructions.
