1. Is 850w enough for 3080 and 5900X?

Yes, it suffices, but it isn't perfect. Under peak usage, an RTX 3080 can consume up to 370W, while a Ryzen 9 5900X can consume up to 150W.

2. Is a 850w power supply enough for 3080Ti?

Although 850W is sufficient, the CXM is not the type of power supply you should use with a 3080Ti. The RMx 850w, which is of superior quality, would be significantly more appropriate. Quality is crucial; a high-quality 850w is preferable to a poor 1000w.

3. What happens if your power supply is too high?

The device might be damaged by too much or too little voltage. Some devices may try to compensate for the absence of voltage by boosting current, but this can harm the device or, in the instance of a motor, cause it to overheat and fail to provide the required torque.

Final Thought
