You’re welcome. A power supply unit (PSU) is an essential component for your PC build, as it provides stable and reliable power to your system and its components. A decent budget PSU should have enough wattage to support your graphics card and other components, as well as some safety features to protect your system from power surges or failures. Based on my web searches, here are some of the best budget PSUs you could get to go with your build:

Corsair CX650M: This is a semi-modular PSU that can deliver up to 650 watts of continuous power with an 80 PLUS Bronze efficiency rating. It has a single +12V rail that can provide up to 54A of current, which is enough for most graphics cards under $200. It also has a 120mm fan that is quiet under low and medium loads. It comes with a 5-year warranty and various protection features, such as over-voltage, over-power, short circuit, and under-voltage protection.
EVGA 500B: This is a non-modular PSU that can deliver up to 500 watts of continuous power with an 80 PLUS Bronze efficiency rating. It has a single +12V rail that can provide up to 40A of current, which is sufficient for most graphics cards under $200. It also has a 120mm fan that is relatively quiet under normal operation. It comes with a 3-year warranty and various protection features, such as over-voltage, over-current, over-power, short circuit, and over-temperature protection.
Cooler Master MWE Gold 550: This is a fully-modular PSU that can deliver up to 550 watts of continuous power with an 80 PLUS Gold efficiency rating. It has a single +12V rail that can provide up to 45.8A of current, which is adequate for most graphics cards under $200. It also has a 120mm fan that uses a fluid dynamic bearing for silent operation and longer lifespan. It comes with a 5-year warranty and various protection features, such as over-voltage, over-current, over-power, short circuit, and over-temperature protection.
These are not necessarily the best or the only budget PSUs you could get, but they are some of the ones that I found based on your criteria. You may want to do more research and compare them based on your specific needs and preferences.
