Is too much PSU bad?
The first rule of thumb is that it’s better to have more power than not enough.
There is no truth to the myth that a large wattage power supply will force too much power into your devices causing overheating and burnout.
The power supply will only provide the needed wattage..
How do I know if I need a new PSU?

What is the lifespan of a PSU?
The psu tier list is a good resource. Power supplies can last a decent lifespan (4-5 years and sometimes longer). It all depends on the quality. The simple PSU would last 2-3 years.
Is 1000w PSU Overkill?
The PSU is the build below should work fine, unless you’re planning on adding another GPU or a bunch more storage. If you want to be really safe and keep alot of free wattage for additions or potential upgrades, and definitely if you’re planning to SLI in the future, just keep the 1000W.
Is 750w PSU too much?
No, an overkill power supply will not damage your PC. … PSU’s are generally most efficient at half load, so if your machine uses 350 watts max, getting a 650 or 750 watt psu would save energy, and a 1000 watt would waste a little. Beyond that, there’s no reason to go small other than size of the actual unit.
Can a blown power supply damage a motherboard?
Most power supply units and motherboards can adjust their voltages to accommodate small power surges. But if it’s a big one, it can fry your motherboard and all the components connected to it.
Can a power supply be too powerful?
