Is a 450W PSU Suitable for a GTX 1660 Super and Ryzen 5 350 System?

When configuring a new PC, the choice of power supply unit (PSU) is often a topic of discussion. A frequently asked question is whether a 450W PSU will be sufficient for a system equipped with a GTX 1660 Super graphics card and a Ryzen 5 350 processor. This article delves into the power requirements, providing a detailed analysis to help you make an informed decision.

Power Requirements

The primary components of your system, the GTX 1660 Super and Ryzen 5 350, have specific power consumption needs:

When you take into account additional components like the motherboard, RAM, storage, and other peripherals, the total power consumption typically ranges between 50-100W. Considering these figures, a 450W PSU seems adequate. However, it's important to ensure that the PSU can deliver the necessary power.

Total Estimate

Under load, the total power consumption of your system, with components in use, would likely be around 250-300W. A 450W PSU would provide sufficient headroom, allowing for a margin of safety.

PSU Quality

It's crucial to choose a reputable brand for your PSU to ensure stability and reliability. Opt for a PSU with at least an 80 Plus Bronze efficiency rating. This recommendation is made based on the fact that PSU efficiency tends to be higher when operating near their half-rated power capacity. A 450W PSU should provide about 400-450W on its 12V rail, ensuring reliable performance for your components.

Future Upgrades

If you plan to upgrade your GPU or add more components in the future, it's advisable to consider a higher wattage PSU. A 650W PSU would be a safer choice, providing ample headroom for future enhancements.

Conclusion

While a 450W PSU can adequately provide power for your system with a GTX 1660 Super and Ryzen 5 350, it's always best to verify the specific PSU ratings and reviews. A reputable 450W PSU with an 80 Plus Bronze rating would be a solid choice for your current setup. Keeping future upgrades in mind, a slightly higher wattage PSU may offer more reliability and peace of mind.
