Can I Upgrade to an AMD RX 460 with a 320W PSU on an HP 6300 MT?

Upgrading your graphics processing unit (GPU) can significantly enhance the performance of your computer. This article aims to provide a comprehensive guide to upgrading to an AMD RX 460 on an HP 6300 MT with a 320W power supply unit (PSU).

Understanding Power Requirements

Before diving into the upgrade process, it is essential to understand the power requirements of the new GPU. The AMD RX 460 typically requires a TDP of around 75W. This makes it possible to operate using the PCIe slot without needing an additional power connector, which is a significant advantage in your situation.

Sizing Up the System Power Consumption

Upgrading to the AMD RX 460 involves not only the GPU but also the overall system power consumption. Here are some key points to consider:

Usage of the Entire System

Your HP 6300 MT's CPU and other components will also draw power, and you must account for their power consumption along with the RX 460. In some cases, you may find that your current 320W PSU is nearly or exceeds its capacity. This can lead to performance issues or instability.

Tools and Recommendations for Assessment

Gathering accurate power consumption data is critical. Here are some recommendations:

Use Power Supply Calculators

Tools such as power supply calculators can help estimate the total power draw of your entire system. This will give you a clear understanding of whether the RX 460 is feasible with your current PSU.

Closely Monitor Power Usage and Temperatures

If you decide to proceed with the upgrade, monitor your system's power usage and temperatures. Look out for any signs of instability or crashes, which might indicate that your PSU is struggling to handle the increased load.

Considerations for Operating within Power Limits

While the RX 460 could technically work within your setup, the limitations of your PSU might lead to performance issues or instability. If possible, it is recommended to upgrade your PSU in the future for better reliability and compatibility with higher-end components.

Alternative Solutions

There are two alternative options you can consider if you are concerned about power limitations:

Fitting a Modern PSU in a Mini Tower

One option is to purchase a cheap standard ATX case like a mini tower and fit a modern PSU with at least 500W. This will offer more power and reliability for your system.

Buying a Suitable Second-Hand Computer

Another option is to buy a second-hand computer that is already compatible with your needs and has a sufficient power supply.

Assessing the Safety of Your Current PSU

Some argue that while the 320W PSU is mentioned as a minimum, it is actually capable of handling the RX 460 with a margin. According to the 320W PSU rating, it can supply up to 16A on the 12V rail, which translates to 192W. This setup has been tested, and even if you were to run all components at 100% load, you would still have a decent gap to the 192W limit.

Conclusion: It is safe to use an AMD RX 460 in your current setup with a 320W PSU, particularly if you avoid cards that need a 6-pin PCIe power adapter, such as the RX560. Future Considerations: If you plan to run more demanding components in the future, consider upgrading your PSU to ensure compatibility and stability.

Final Thoughts

While the AMD RX 460 can potentially work with your HP 6300 MT and 320W PSU, careful consideration and monitoring are essential to ensure optimal performance and stability. Always assess the total system power consumption and upgrade your PSU if necessary to future-proof your system.
