The power supply does not have enough wires to power the processor. There are 8 + 4 pins on the mother, and only 8 pins on the power supply. What to do?

Question

Computers

Be quiet system power 9 power supply 600W. Msi mpg z490 gaming plus mother. The computer turns on, but it's terribly stupid. The adapter from molex to 4 pin for the processor was bought and installed, after that it got a little worse.
Is there a possibility that the marriage of the processor or something like that? Or is it just not enough food? Even the bios is stupid and the system is loaded for a long time.

Answer 1

Don't do nonsense. Of course, you only made things worse with the adapter.
You have a processor at TDP = 65W, not only 8 pin is enough for him , but even 4 pin may be enough (as on very old PSUs).
8 + 4 is required for top -end overclocked processors, but not through an adapter, of course.
Conclusion: these adapters are useless, because with a low TDP everything works fine even without them (and it only gets worse with them), and with a high TDP they won’t help at all, with a high TDP you need a suitable PSU.

I would replace the PSU or modular

What is the rest of the iron? Calculate how much food it eats.
