A gaming PC can pull hundreds of watts while you play and still draw power when it appears to be idle. The best smart power monitoring plugs for gaming PCs show that usage in real time, record energy in kilowatt-hours, and add remote control without requiring you to reach behind a desk.
A smart power monitoring plug sits between a wall outlet and your equipment. It measures voltage, current, watts, and accumulated kWh through an app or display, while compatible models add schedules, scenes, voice control, and remote access; for a broader starting point, see our smart plug reviews.
We compared the specifications and review evidence for this lineup with gaming setups in mind: a desktop tower, one or more monitors, speakers, and accessories. I paid special attention to load ratings, measurement features, network requirements, platform support, and the limitations that matter when a high-draw GPU is connected.

1. Kasa Smart Plug Mini KP115 gives precise energy readings
Kasa Smart Plug Mini with Energy Monitoring, KP115
15 A
1800 watts
2.4GHz Wi-Fi
UL certified
Pros
- Precise voltage current power and energy readings
- Compact design keeps the adjacent outlet usable
- Local control capability
- Overheating protection and fireproof shell
Cons
- Requires 2.4GHz Wi-Fi
- No built-in display
I would start with the KP115 when the main goal is seeing what a gaming PC actually consumes. Its 15 A, 120-volt, 1800-watt specification gives a desktop setup plenty of rated headroom for ordinary gaming use, while the monitoring system reports voltage, current, power, and energy.
The compact body is practical behind a desk because it does not block the neighboring receptacle. Setup uses 2.4GHz Wi-Fi, and the product data lists UL certification, overheating protection, and a fireproof shell.
I like this format for comparing idle, gaming, and shutdown readings in one app. Reviewers praise the precise measurements, reliable operation, and local-control potential, although you need a phone or compatible interface because there is no integrated screen.
For a tower, monitor, and powered accessories, connect the devices you want to measure as a group, then watch the live watt figure during a demanding game. Do not treat the plug as a surge protector; use a suitable protected power solution when that protection is required.
Will it fit behind a gaming desk?
Yes, the compact 2.62 by 1.57 by 1.5 inch body is designed to preserve access to the adjacent outlet. That helps when a monitor, router, or desk lamp needs its own connection.
What should you monitor first?
Record the PC’s idle watts, then compare them with a game running and with the system shut down. The difference helps reveal standby draw and whether accessories should share the same measurement point.
2. Amazon Smart Plug keeps Alexa control simple
Amazon Smart Plug, Works with Alexa, Simple Setup, Endless Possibilities
Alexa control
No hub required
Auto-reconnection
Compact body
Pros
- Extremely easy Alexa setup
- Responsive voice commands
- Reliable reconnection after outages
- Compact design keeps the second outlet free
Cons
- Alexa ecosystem only
- No energy monitoring
The Amazon Smart Plug is the clearest choice for a gaming room already built around Alexa. It handles on and off commands through the Alexa app or compatible devices and does not require a separate smart-home hub.
Its compact shape leaves the second outlet open, which is useful behind a PC desk. The product data identifies Wi-Fi connectivity and automatic reconnection after power or Wi-Fi interruptions.
This is a control plug, not an electricity usage monitor. I would use it to power-cycle selected accessories or schedule a lamp, but pair it with a separate meter when the purpose is tracking gaming PC consumption.
Remote power control also has a safety boundary: cutting power to a running computer is not the same as shutting down through the operating system. Use it for equipment that can tolerate switched power, or configure the computer’s own settings before relying on remote routines.
Is it suitable for measuring PC energy?
No, the supplied product information lists no energy monitoring. Choose a plug with watt and kWh readings if measurement is central to the setup.
Who benefits most from this plug?
Alexa households that want straightforward voice and app control benefit most. Its reliable reconnection and compact housing reduce everyday friction.
3. EIGHTREE Smart Plug 4 Pack adds broad voice compatibility
EIGHTREE 15A Smart Plug Works with Alexa & Google Home, Smart Outlet 4 Pack
15 A rating
Alexa and Google Home
2.4GHz Wi-Fi
1100 watts listed
Pros
- Works with Alexa and Google Home
- Quick setup and stable connection
- Compact round design
- Remote control from anywhere
Cons
- 2.4GHz Wi-Fi only
- No power measurement in Smart Life
The EIGHTREE four-pack makes sense when a gaming station has several separately controlled devices. You can assign plugs to a monitor, speaker system, desk lighting, or charging area while keeping voice control in either Alexa or Google Home.
Although it carries a 15 A label, the listed wattage is 1100 watts, so I would use that lower figure as the practical planning limit. The round mini design is less intrusive than a large block in a crowded receptacle.
Setup is described as fast and hub-free, with a stable 2.4GHz Wi-Fi connection. That is a good fit for a normal home network, but weak signal near a desk can still cause the connectivity problems forum users commonly report.
The key limitation for this roundup is measurement. The review data says the Smart Life app does not provide built-in power measurement, so this model is better for switching and automation than for logging PC watts or kWh.
Can it handle a complete gaming setup?
Use the listed 1100-watt figure when planning the connected load. A tower with multiple displays should be checked as a combined system rather than judged from the PC label alone.
Is it useful for automation?
Yes, remote control and voice support suit routines for lights and accessories. It is less suitable when the main requirement is detailed electricity usage data.
4. MECHEER Watt Power Meter shows readings on its LCD
Watt Meter Power Meter Plug Home Electricity Usage Monitor 7 Modes Display
Watts volts amps and kWh
LCD backlight
Seven display modes
Adjustable 3680W overload
Pros
- Clear backlit display
- Measures watts volts amps and kWh
- Seven monitoring modes
- Data memory when unplugged
Cons
- Not a networked smart plug
- Display requires direct viewing
The MECHEER PM01-US is the specialist tool here for anyone who wants a direct reading without an app. It displays power, energy, voltage, current, frequency, power factor, and cost fields, giving a fuller snapshot than a basic switch.
Its LCD and adjustable backlight make it easy to inspect beside a desk. The listed overload setting is adjustable from 0 to 3680 watts, and the device can retain measurements when unplugged.
I would use this watt meter to establish a baseline for a gaming PC before choosing automations. Reviewers specifically praise the readable screen, accurate measurements, and seven display modes.
There is no Wi-Fi, voice control, or remote switching in the supplied data, so it cannot turn the computer on from another location. That is not a flaw if your aim is measurement at the outlet, but it rules out app-based history and routines.
Why use a display meter instead of an app?
A display meter works without network pairing and shows the reading at the socket. It is useful for a quick diagnostic check before moving to connected automation.
What does it reveal about a PC?
Watts show the immediate load, while kWh accumulates usage over time. Voltage, amps, and power factor add context when you compare game sessions or peripherals.
5. kuman Watt Meter stores useful power measurements
Upgraded Watt Meter, Home Electricity Usage Monitor, Plug-in Socket Power Meter, Power Watt Voltage Amps Meter Tester, Overload Protection
Power and energy readings
LCD display
Overload warning
Data memory
Pros
- Measures power voltage amperage and energy
- Overload protection with warning
- Stores data when unplugged
- Clear instructions and accurate readings
Cons
- Screen is difficult from the side
- Backlight turns off quickly
The kuman KW47-US serves the same diagnostic role as a kill a watt plug: connect it between the outlet and the gaming PC, then read the electrical data directly. It measures power, voltage, amperage, frequency, power factor, energy, and cost fields.
Its data-memory function is helpful when a short test ends and you want to preserve the result. Overload protection adds a warning, while the ABS housing and LCD keep the interface familiar.
Reviewers report that this type of meter helped identify phantom power waste and delivered accurate voltage and power readings. I would use it to compare shutdown draw with sleep-mode draw before deciding whether a smart plug is needed.
The screen is not ideal from an angle, and the backlight turns off after a few seconds. Since the unit is not connected, it cannot provide remote PC power control, schedules, or smart-home scenes.
Does it replace a Wi-Fi power plug?
It replaces the measurement function, not the connected features. Choose it when a local reading matters more than alerts, voice commands, or remote access.
How can it find phantom load?
Measure the PC while shut down, then unplug peripherals one at a time. A persistent reading identifies equipment that continues drawing power in standby.
6. Kasa Matter KP125MP2 connects energy tracking with broad platforms
Kasa Matter Smart Plug with Energy Monitoring, KP125MP2, 15A/1800W Max
Matter and Wi-Fi
15 A and 1800 watts
LAN control
Energy monitoring
Pros
- Matter-compatible integration
- Energy monitoring over time
- Smooth LAN control when internet is offline
- Compact flame-retardant design
Cons
- Monitoring is not yet available in SmartThings
- Platform features vary
The KP125MP2 is the connected option I would consider when a gaming room spans several smart-home platforms. Matter support brings compatibility with Siri, Alexa, Google, and SmartThings ecosystems, while the plug also records energy use.
The 15 A and 1800-watt specification suits a typical desktop power path, and LAN control can continue when the internet goes offline. The compact, flame-retardant design is helpful behind a workstation.
Its most important caveat is platform-specific behavior. The product data says energy monitoring does not yet work in SmartThings, so verify that your chosen controller exposes the readings you need.
For privacy-conscious users, local control is a meaningful advantage, especially because forum discussions show hesitation around cloud dependence and TP-Link security. A Matter label does not remove the need to check firmware, account, and network settings.
Does Matter make it better for gaming rooms?
Matter helps when household devices use different ecosystems. It does not itself measure PC load; the plug’s energy-monitoring feature performs that job.
When is LAN control useful?
LAN control is useful when local routines should keep working through an internet interruption. It also appeals to users who prefer reducing cloud dependence.
7. Govee Smart Plug 4 Pack combines monitoring with Bluetooth
Govee Smart Plug with Energy Monitoring, WiFi Bluetooth Outlet, 4 Pack
Real-time energy monitoring
Wi-Fi and Bluetooth
15 A and 1800 watts
Group control
Pros
- Real-time power current and voltage tracking
- Historical energy data
- Wi-Fi and Bluetooth connectivity
- Alexa and Google Assistant support
Cons
- Does not support 5GHz Wi-Fi
- Automation logic could be more flexible
The Govee four-pack fits a gaming room where you want separate readings for the tower, displays, lighting, and entertainment gear. Its monitoring system tracks power, current, and voltage in real time and keeps historical data in the app.
Wi-Fi and Bluetooth give the setup two connection paths, while scheduling, grouping, Alexa, and Google Assistant support cover common routines. The listed electrical capacity is 15 A and 1800 watts at 120 volts.
Reviewers praise the simple setup, reliable performance, and integration with the Govee ecosystem. I would group the PC and monitor only when I want total station readings; separate plugs provide better information about which device is responsible for a spike.
Like many products in this category, it uses 2.4GHz Wi-Fi rather than 5GHz. The review data also notes that the automation logic could be more versatile, so advanced Home Assistant users may want a more open local-control path.
Why choose four individual plugs?
Individual outlets let you compare a tower, monitor, speakers, and lighting instead of receiving one combined number. That makes troubleshooting and standby-load reduction more targeted.
Is Bluetooth important here?
Bluetooth can simplify initial access and provide another nearby connection method. The product still relies on its stated Wi-Fi requirements for connected routines.
8. Aqara Zigbee Smart Plug adds local-style hub integration
Aqara Zigbee Smart Plug with Energy Monitoring, Overload Protection
Zigbee connection
Energy monitoring
15 A support
Aqara hub required
Pros
- Energy monitoring
- Acts as a Zigbee signal repeater
- HomeKit integration
- Schedule timer and scene support
Cons
- Requires an Aqara hub
- Three-prong design excludes some two-prong devices
The Aqara plug is aimed at a Zigbee home rather than a plug-and-play Wi-Fi setup. It requires an Aqara hub, then adds energy monitoring, schedules, timers, scenes, smartphone control, and a repeater function for the Zigbee network.
Its 15 A, 120-volt specification is appropriate for many desktop systems when the total load remains within the device and circuit limits. The three-prong design should be checked against the equipment you intend to connect.
HomeKit support makes this a useful choice for Apple households that already use Aqara hardware. Reviewers also value its role as a signal repeater, which can improve the wider Zigbee mesh.
The hub requirement adds a setup step and another component near the router. Forum users often prefer Zigbee for local control, but they also point out that hub compatibility must be confirmed before buying.
Can it support a high-draw PC?
The listing specifies 15 A support, but the safe choice depends on the complete connected load and circuit. Check the computer’s measured draw rather than relying only on the power supply rating.
What does the repeater function add?
The plug can extend the Zigbee network as well as switch and monitor the connected device. That makes it more useful in a larger smart-home mesh than a standalone meter.
9. Emporia Energy Monitor keeps connected tracking straightforward
Emporia Energy Monitoring Smart Plug, WiFi Smart Outlet Plug Works with Alexa and Google Home – 15a WiFi Outlet with Timer, Mobile App, Home Energy Monitor, Scheduling – 2.4ghz WiFi Only (1 Pack)

Cons
- 10 A continuous load rating
- 2.4GHz Wi-Fi only
The Emporia smart plug focuses on accessible energy tracking and remote control. It works over 2.4GHz Wi-Fi and supports Alexa and Google Home, with scheduling and timer functions for repeatable routines.
The electrical limits need careful attention: the specifications list 10 A and 1200 watts at 120 volts. I would reserve it for a measured load that stays comfortably below those figures rather than a power-hungry tower with several accessories.
Its app-based design suits a home office or a modest gaming station where basic energy history matters. Reviewers appreciate the monitoring capability and scheduling, while the supplied review data calls out the lower continuous-load rating.
Use the timer to manage peripherals or a display, but avoid cutting power to a running computer. For a gaming PC, confirm the actual wall draw with a watt meter first, especially if the system uses a demanding graphics card.
Who should avoid this plug?
Users whose measured setup approaches 1200 watts should choose a product with a more suitable rating. A multi-monitor arrangement can raise the combined load faster than expected.
What is its strongest feature?
Its balance of energy monitoring, scheduling, timer control, and voice support makes everyday tracking simple. The 2.4GHz requirement is the main network constraint.
10. Tapo P110M 4 Pack brings Matter and energy statistics
Tapo Smart Plug, Matter Compatible, Energy Monitoring, P110M(4-Pack), 15A
Matter-certified
Energy statistics
15 A and 1800 watts
Overcharge prevention
Pros
- Matter-certified compatibility
- Energy tracking with statistics
- Bill-estimation feature
- Overcharge prevention and power management
Cons
- Larger body may block adjacent outlet
- Matter runs over Wi-Fi without Thread
The Tapo P110M four-pack is built for multiple rooms or multiple measurement points. Matter certification, energy statistics, voice control, remote access, and power-management features give it a broad smart-home role.
The listing specifies 15 A and 1800 watts, with 2.4GHz Wi-Fi connectivity. It can estimate an energy bill from its tracking data, which may help translate gaming sessions into a clearer household usage picture.
Reviewers praise the energy tracking, scheduling, and platform support. The physical package is larger than some mini plugs, so I would check neighboring outlet clearance before placing it behind a desk.
This product uses Matter over Wi-Fi rather than Thread, a distinction worth understanding when planning a mixed network. Overcharge prevention and power management are useful additions, but they do not replace checking the PC’s real draw and the circuit’s limits.
Is the four-pack useful for a gaming room?
Yes, separate plugs can track the tower, displays, and accessories independently. That makes seasonal or session-based comparisons more informative than one combined reading.
What is the main installation concern?
Measure the available outlet space because the larger body may block the adjacent connection. Confirm the 2.4GHz network and Matter controller before setup.
How to Choose a Smart Plug for a Gaming PC?
Choose a smart plug by matching its electrical rating, measurement method, network protocol, and control features to your exact gaming setup. The best device is not automatically the one with the most smart-home features; it is the one that safely measures or switches the load you actually have.
Start with the measured wattage and amp capacity
Gaming PC power consumption changes with the processor, graphics card, game, monitor count, and peripherals. GPUs can draw roughly 100 to 450 watts in the research context, but the complete setup can be higher, so measure at the wall and compare the result with the plug’s stated limit.
A 15 A, 120-volt device is commonly listed at 1800 watts, while the Emporia is listed at 10 A and 1200 watts and the EIGHTREE at 1100 watts. Treat the lowest applicable rating as the boundary, and remember that a power supply’s maximum label is not the same as measured consumption.
Decide whether you need live data or remote switching
Energy-monitoring models report watts and accumulated kWh, making them suitable for an electricity monitor plug or home energy monitor plug role. The Amazon and EIGHTREE products in this lineup focus on control and do not provide the same measurement data.
A standalone watt meter such as the MECHEER or kuman gives an immediate local reading without Wi-Fi. A connected plug adds history, schedules, scenes, voice control, and remote access, but its app and network become part of the measurement workflow.
Match Wi-Fi, Zigbee, Matter, and local-control needs
Most Wi-Fi products here require 2.4GHz, not 5GHz. A weak signal near a desk can cause interruptions, while Zigbee models require a compatible hub and Matter models depend on a Matter controller and the transport supported by the product.
Forum discussions show strong interest in local control, especially among Home Assistant users and privacy-conscious households. Matter and LAN features can help, but check exactly which readings and automations remain available locally; a certification label alone does not promise identical functions in every platform.
Use Wake-on-LAN for the computer, not a blind power cut
A wake on LAN smart plug is usually a pairing of two technologies rather than a special plug feature. Wake-on-LAN sends a network packet to a compatible computer, while the smart plug supplies remote switching; neither approach should abruptly remove power from a running system.
Enable the motherboard’s Wake-on-LAN setting, test the network behavior, and use the plug for accessories or a controlled power-cycle routine. For downloads and updates, the computer’s operating-system settings are safer than cutting the outlet while files are being written.
Plan for monitors and phantom load
Measure the tower alone first, then test displays, speakers, lighting, and chargers. A four-pack such as the Govee or Tapo can show the separate contribution of each group, while one plug gives a simpler total for the station.
PC standby power is the electricity consumed after the visible workload stops. A phantom load plug can reveal that residual draw, but the best response may be a software shutdown, display sleep setting, or a schedule for accessories rather than switching the entire computer.
Consider outlet shape, protection, and privacy
Compact plugs preserve the second receptacle, while larger models may block it. None of the supplied product data should be treated as a substitute for a properly rated surge protector, UPS, or circuit protection for sensitive gaming hardware.
Forum users also mention TP-Link privacy concerns and cloud dependence with some Tuya or Smart Life products. Review the account, firmware, platform, and local-control options that fit your comfort level before pairing a plug with your home network.
If you are still choosing the computer itself, our guides to prebuilt gaming PCs for 4K gaming and budget gaming PCs can help you estimate the rest of the setup.
Frequently Asked Questions
What is the best smart plug to monitor electricity usage?
The Kasa KP115 is the strongest overall monitoring choice in this lineup because it lists precise voltage, current, power, and energy readings in a compact 15 A, 1800-watt design. The MECHEER is better when you want a direct LCD reading without an app.
What is the best PC monitoring software for gaming?
The products here monitor electricity at the wall rather than frame rates, temperatures, or in-game performance. Use a smart plug app for watts and kWh, and use the computer’s own monitoring software for hardware and gaming metrics.
What is the best power extension for a gaming PC?
Choose a properly rated power solution that accommodates the tower, monitors, and accessories without exceeding its amp or watt limit. A smart plug adds measurement or control, but it does not replace a suitable surge protector or UPS when those are needed.
Which smart power plug is the best?
The Kasa KP115 is the best all-around pick here for gaming PC energy monitoring because it combines precise readings, compact construction, safety details, and a 15 A, 1800-watt specification. Choose a Matter, Zigbee, or display meter alternative when your network or workflow calls for it.
What are the disadvantages of smart plugs?
Smart plugs can require 2.4GHz Wi-Fi, a hub, or cloud accounts; some lack energy monitoring, some block the adjacent outlet, and platform features may differ. They also should not be used to abruptly cut power to a running computer, and their electrical rating must match the complete connected load.
Final Recommendation
The Kasa KP115 is my editor’s choice for most gaming PC owners who want clear energy data, a compact form, and a 15 A, 1800-watt specification. The MECHEER is the better diagnostic meter when you want a local screen, while the Kasa KP125MP2 and Tapo P110M suit Matter-based homes.
Measure the tower and every major accessory, confirm the plug’s rating, and choose the network style you can maintain. Recheck the setup as your hardware changes in 2026, then use the readings to reduce standby draw without interrupting a running computer.
