Running dual screens on a system with a 450W power supply and an Nvidia 9600 GT should be possible, although it will depend on the specific power draw of your system components while under load. Here's a breakdown to help you assess if it's feasible: 1. Power Supply: A 450W power supply is reasonable for a system with a single graphics card like the Nvidia 9600 GT and other standard components. Adding another monitor won't drastically increase the power consumption, as monitors are generally low power devices. 2. Nvidia 9600 GT: The Nvidia 9600 GT is an older graphics card but should still be capable of handling dual monitors without issues. The specifications provided seem adequate for dual-screen setup. - Memory Capacity: 512MB should be sufficient for running dual monitors. - Interface: PCIe 2.0 is compatible with most modern motherboards. 3. Compatibility: Make sure your system has the necessary outputs for dual monitors. The Nvidia 9600 GT typically has multiple display outputs like DVI, HDMI, and VGA. 4. System Load: Running dual monitors might slightly increase the power consumption, but with a 450W power supply, you should still have enough headroom unless your system has other power-hungry components. 5. Monitor Power Draw: Monitors, especially older CRT models like the Compaq FS 7550, are not power-hungry devices. They should not strain your power supply significantly. In conclusion, based on the specifications you provided, it is likely that you can run dual screens with your setup. However, it's always recommended to monitor your system's power consumption, especially under load, to ensure stability. It's also wise to consider any future upgrades or additional components that may increase power requirements.
