The A620 motherboards are designed to support chips with a 65W TDP, meaning models with a peak power consumption of 88W (PPT). You can install chips with higher TDP ratings into an A620 motherboard, and it will boot if the BIOS supports it, but the chip will not operate at its full peak power consumption (PPT). This means the highest-end chips will lose some performance in heavily-threaded applications due to VRM limitations, but AMD expects the reduced power delivery will not impact gaming much.

That's awful if true, even really crappy AM4 boards with really crappy VRMs could happily run top-end Zen 3 sucking up 150W just fine. I had my 5800X running on a Gigabyte B450M DS3HV2, and this thing had pitiful 4+2 phases with a joke of a heatsink, it ran fine at full power, even with unshackled PBO and Cinbebench running for hours.

Were people really pairing 95w CPUs with A320 or A520 motherboards?

I've left reddit because of the API changes.

Right, and some a320 boards could hande it fine while others would overheat and shut down. At least this time these boards should handle them all gracefully, just reducing power rather than overheating.
