No de energia no Ryzen 7
No de energia no Ryzen 7
I bought the Ryzen 7 and MSI B450 Tomahawk recently. The packaging mentions Ryzen 3 ready, so I assume the board doesn’t need a BIOS update. My power supply is still functional after only a few days, and it’s set up on my makeshift test bench. I think the power switch is connected correctly, but nothing seems to work.
Board support isn't guaranteed just because it's physically attached. Manufacturers have released updates for older boards to include compatibility with newer CPUs. Still, updating the BIOS on older chipsets is necessary for full functionality. AMD provides a free solution: https://www.amd.com/en/support/kb/faq/pa-100. Your manual may indicate that updates are possible even without a supported CPU—check it. Page 40 of the manual covers this detail. For the BIOS flash button instructions, see page 29.
Avoid this page. Watch the video—they're performing without a CPU.
