PSUsdon’t last forever, and the build quality and efficiency have gone up over time.

Compare the estimated load to the rating of your current PSU.
You won’t always end up increasing the load, by the way.
Either way, you’ll have a new value to compare.

When we swapped the GPUs in our calculation to a beefier model, our load calculation jumped to 675W.
If you’re thinking that 675W is starting to sound like space heater territory,you’re not wrong.
Now it’s time to talk about headroom and risk tolerance.

But with modern, high-quality PSUs withproper efficiency certification, that’s a bit extreme.
In our original calculation, we have a 750W PSU with a 445W load.
That load is approximately 59%, leaving us with a 41% headroom.
That’s a pretty substantial amount of wiggle room.
You might not, of course, and you could even slightly undervolt your card to fix that issue.
