Windows power plans are probably something you don't think about until you have to, especially on a desktop PC. These settings control a lot of your PC's behavior when it comes to gaming performance, file access, and network connectivity. Many users never bother to change the default power plan on their Windows PC. While these settings might seem relevant only for laptops, even desktop behavior is likely to be affected if you're running the "wrong" power plan for your needs. It doesn't take long to understand the differences between the pre-configured Windows power plans or create a custom plan for yourself.

You don't need "High Performance" for the best results

"Balanced" works well even on desktops

A common recommendation for Windows users, especially on desktops, is to switch to the "High Performance" power plan the moment you set up a new PC. This advice is linked to the fact that this particular plan doesn't let your CPU drop its clock speed during idle scenarios. Plus, it prevents other devices like your network adapter and USB peripherals from going into low-power states after a period of inactivity. This high-performance mode essentially prevents the minor latency you might experience when launching games or accessing files on your SSD or hard drive, because the system is always working at 100%.

That being said, the "High Performance" plan isn't necessary to ensure peak performance on your gaming PC. Even the "Balanced" plan will allow your CPU and storage drive to work as fast as needed when the workload demands it. The minor delay in ramping up the clock speed or RPM introduces an imperceptible effect on launch time or performance. The "High Performance" mode keeps your CPU running at its boost clock even when the system doesn't need it, keeping the temps and fan speeds higher than they need to be. Switching to "Balanced" will allow you to enjoy peak performance when you need it while ensuring low CPU temps and fan noise when you don't.

The "Balanced" mode works especially well for laptop users who want to conserve battery life without taking things to another extreme with the "Power saver" plan.

There's an "Ultimate Performance" plan as well

It pushes your hardware for very little in return

I didn't know about this plan until recently. I came across a Reddit post mentioning how to enable it in the Command Prompt, and compared it to the "High Performance" plan that I was already using. It turns out that the only real difference is that it's even more aggressive in preventing CPU idle states, hard drive spin-down, and peripheral power management, forcing almost all your components to work full throttle all the time. You might not see it in Windows settings, but you can enable the "Ultimate Performance" plan using a Command Prompt window. Windows 11 users will probably not see this option anymore, but Windows 10 still has it.

For almost everyone, the "Ultimate Performance" plan does very little in reality. The "Balanced" and "High Performance" plans are already enough to get the most out of your hardware, even in gaming and other intensive workloads. The "Ultimate Performance" plan is mostly relevant to workstation builds running heavy parallel workloads, not the typical desktop or laptop. It increases the energy consumption on your desktop and laptop, and will probably deplete your battery even faster without offering anything tangible in return. If you're on this extreme power plan on your Windows PC, you can safely switch to "Balanced" or "High Performance" without any hit to performance.

You can even create a custom power plan

Customize everything just the way you like it

The default power plans on Windows are good enough for most use cases, but if you want total control over your PC's behavior, you should consider a custom power plan for your exact needs. You can change settings like the processor idle timers, USB suspension timers, throttle states, display turn-off timer, and more. While most of these settings might not interest the average user, some users attempt to maximize their framerates and minimize latency by tweaking settings not found even in the "Change advanced power settings" dialog box.

A custom power plan can be useful for laptop users who want to use the "Power saver" plan for the best battery life, but still want to keep their network adapter and a few other devices active all the time. On desktops, you can create a plan that disables selective suspend for Bluetooth alone while keeping it enabled for your USB devices. You could also keep "Minimum processor state" high enough while allowing full power for the GPU, and set the cooling policy to "Active" for a custom gaming plan. On the other hand, you could enable 90% or 100% "Minimum processor state" and no power savings for any component for a custom workstation plan. Most people will be satisfied with the default power plans, but you can unlock otherwise hidden combinations of settings to achieve exactly the kind of power management you desire.

A change in your Windows power plan might be overdue

If you've been wondering why your CPU idle temps stay unusually high, the SSD feels slow to respond, or the network seems sluggish, it might be linked to using the wrong power plan. Switching between the various plans can change a lot of your PC's behavior that you might attribute to aging hardware or random Windows bugs. You can even create a custom power plan to dial in the exact behavior you want from your CPU, network adapter, and storage drive under various workloads.
