Advice please (and apologies if this topic has been covered before - I couldn't find it). New mini-pc working fine, case has 450W power supply. The spec sheet warned that the consumption would be 315W and to "consider upgrading the power supply". None of the cases had a higher wattage. Can I / should I replace the power supply with a higher rating (say 600W), or more to the point is this necessary? Current build does not seem to be running hot and certainly is not giving problems
