For two 5V 90W LED strips, you would need a power supply that can provide a total of 180W (90W per strip). Since the LED strips operate at 5V, you would need a power supply that can deliver at least 36A (180W / 5V = 36A). It is important to choose a power supply that can handle the total power requirements of both LED strips to ensure they operate properly and safely. **

For two 5V 90W LED strips, you will need a power supply that can provide at least 180W of power in total. Make sure the power supply is rated for 5V output to match the LED strips' voltage requirement. Additionally, ensure that the power supply has enough current capacity to handle the combined load of both LED strips, typically around 36A (180W / 5V = 36A). It is recommended to use a power supply with a slightly higher wattage rating to ensure stable and reliable performance. **

The adapter for 3pin 5V to 4pin 12V is a cable that allows you to connect a 3-pin 5V fan to a 4-pin 12V motherboard header. This adapter typically has a 3-pin female connector on one end and a 4-pin male connector on the other end, allowing you to convert the voltage and still use the fan with the motherboard. It is important to note that using this adapter may result in the fan running at a lower speed due to the lower voltage, so it's important to check the fan's compatibility with the lower voltage. **

To upgrade the Dell Optiplex 790 for gaming, you can start by upgrading the RAM to at least 8GB or higher to improve performance.
