Ultimate Power Plan: What It Is & How to Use It

The Ultimate Power Plan is a hidden Windows power scheme designed to squeeze maximum performance from a PC by disabling power-saving features like sleep, USB suspension, and CPU throttling. You enable it through Command Prompt or PowerShell, then select it in the Power Options control panel. This article explains what it actually does, how to turn it on, and whether you should use it.

Formula

The calculator above computes average pace and speed from a finish time and distance. The formulas are:

Pace = Finish Time (minutes) ÷ Distance (km)

Speed = Distance (km) ÷ (Finish Time (min) ÷ 60)

Where:

• Finish Time (t) – total time taken, in minutes.
• Distance (d) – race or run distance, in kilometers.
• Pace – minutes per kilometer (min/km).
• Speed – kilometers per hour (km/h).

Worked Example

Using the default values: t = 50 minutes, d = 10 km.

Pace = 50 ÷ 10 = 5.00 min/km

Speed = 10 ÷ (50 ÷ 60) = 10 ÷ 0.8333 = 12.00 km/h

So a 10 km run in 50 minutes gives an average pace of 5:00 per kilometer and an average speed of 12 km/h.

Why the Ultimate Power Plan Exists

Windows includes several power plans: Balanced, High Performance, and Power Saver. The Ultimate Performance plan was introduced in Windows 10 (version 1803) for advanced users, especially those running heavy workloads like video editing, 3D rendering, or scientific computing. Microsoft designed it to remove micro-latencies in CPU and disk management, letting the hardware run at full speed without the OS stepping in to save power.

It is not available by default in the Power Options list. You have to enable it with a command, and it only appears on Windows 10 Pro, Enterprise, or Workstation editions – not on Home editions. In Windows 11, the same hidden plan exists, but Microsoft has not made it more accessible; the command still works.

How to Enable the Ultimate Power Plan

Enabling the plan takes less than a minute. You need administrator rights.

1. Press Win + X and choose Terminal (Admin) or Command Prompt (Admin).
2. Type the following command and press Enter:
   powercfg -duplicatescheme e9a42b02-d5df-448d-aa00-03f14749eb61
3. You will see a message like: “Power Scheme GUID: … (Ultimate Performance)�.
4. Open Control Panel → Power Options.
5. Select Ultimate Performance from the list.

If you want to remove it later, run powercfg -delete e9a42b02-d5df-448d-aa00-03f14749eb61 as admin.

What the Ultimate Power Plan Actually Changes

Compared to Balanced or High Performance, the Ultimate plan sets these policies:

• CPU minimum and maximum processor state – both forced to 100%, disabling dynamic frequency scaling.
• Disk timeout – set to 0, meaning the hard drive never spins down.
• USB selective suspend – disabled, so USB devices stay fully powered.
• PCI Express link state power management – turned off.
• Processor performance boost mode – set to “Aggressiveâ€� or higher.

The net effect is that the CPU stays at its maximum clock speed whenever the system is active, and components like SSDs and GPUs do not enter low-power idle states. This can reduce micro-stutters in real-time audio processing or high-refresh gaming, but it also means the system draws more power and generates more heat.

When You Should (and Shouldn’t) Use It

The Ultimate Power Plan is not a magic performance booster. For everyday tasks like web browsing, office work, or watching videos, you will see no difference – the CPU is already fast enough. It only matters when your workload is sustained and CPU-bound, such as:

• Video encoding or 3D rendering
• Large data simulations
• Real-time audio processing with low latency
• Competitive gaming where frame-time consistency matters

Do not use it on a laptop unless it is plugged in. The plan disables battery-saving features, so battery life will drop noticeably. Also, on a desktop with a weak cooling solution, the constant maximum clock speed can push temperatures higher. If your PC already runs hot, stick with Balanced or High Performance.

Common Problems and Fixes

Plan does not appear after command: Make sure you are on Windows 10 Pro/Enterprise/Workstation or Windows 11 Pro/Enterprise. It does not work on Home editions. Also, verify you ran the command as administrator.

Plan disappears after reboot: Some OEMs (like laptop manufacturers) hide the plan. Re-run the command, or check if your OEM power management software overrides it.

No performance improvement: If your workload is GPU-bound or network-bound, the CPU power plan won’t help. Also, check that your CPU is not thermally throttling – check temperatures with a monitoring tool.

Battery drains fast: This is expected. Switch back to Balanced when on battery.

Ultimate vs. High Performance vs. Balanced

Here is a quick comparison:

• Balanced: CPU state varies from 5% to 100% based on load. Best for most users – saves power, reduces heat, and still boosts when needed.
• High Performance: CPU min state fixed at 100%, but other power-saving features (like USB selective suspend) remain enabled. Good for desktop gaming.
• Ultimate Performance: Everything set to maximum – CPU, disk, USB, PCIe. Only for specialized workloads.

In practice, the difference between High Performance and Ultimate is small. You might see 1–3% improvement in benchmarks, but not in real-world tasks. The main benefit is reduced latency spikes, not higher average speed.

Frequently Asked Questions

Does the Ultimate Power Plan damage my PC?

No, it does not damage hardware. It simply prevents the OS from powering down components. However, it can increase heat and power draw, so ensure your cooling is adequate. If temperatures exceed safe limits (usually 90°C for CPUs), the CPU will throttle itself anyway.

Can I use it on Windows 11 Home?

No. The Ultimate Performance plan is only available on Pro, Enterprise, and Workstation editions. Home editions lack the necessary power settings. You can try third-party tools, but they are not recommended or supported by Microsoft.

Should I use it for gaming?

For most games, High Performance is sufficient. Ultimate can help if you experience micro-stutters in CPU-heavy games, but the difference is often negligible. Try it and compare frame times with a tool like MSI Afterburner.

How do I know if the Ultimate Power Plan is active?

Open Control Panel → Power Options. The active plan has a radio button selected. You can also run powercfg /getactivescheme in Command Prompt – it will show the GUID and name.

Can I customize the Ultimate Power Plan?

Yes, you can edit its settings just like any other plan. Click “Change plan settings� and adjust sleep, display, or advanced settings. However, the whole point is to use it as-is; changing settings may reduce its effectiveness.
