Is higher Watts better for PC?

Running for sustained periods at full capacity also creates stress to the electronic components, increasing the potential for failure. Therefore, it is better to run a higher wattage unit at half capacity than a lower wattage unit at full capacity.

Does a 750W PSU always use 750W?

No, that’s just the maximum rated supply.

Is 600W enough for a gaming PC?

A gaming PC should have enough watts to run everything smoothly and account for any future upgrades to the system. For most people, that means somewhere between 500 and 550 kilowatts. For others, it could mean as few as 450 or as many as 600.
