What’s a reliable, affordable power supply for my Ryzen 5 5600 and RTX 9060 16GB?

I’d skip the PF600. It’s a budget unit with a poor reputation, so saving a little money there probably isn’t worth the risk. Look for a model rated B-tier or better on a reputable PSU tier list, preferably with a longer warranty. A good 650W unit should be a sensible target if the graphics card’s official requirements support it.

The MSI MAG A650BN would be a more reasonable direction than the PF600 if it’s well priced where you live. Just make sure it has the correct PCIe power connectors and enough headroom for your particular card. If you can afford it, choosing a better-reviewed 650W Gold model is preferable to buying the cheapest available unit.

Before buying anything, check the exact GPU model and its manufacturer-recommended power supply rating. Product names and power requirements can vary, and the official specification is more reliable than a general estimate. Seasonic has a solid reputation, and Corsair also has several dependable budget and midrange options.
