PSU Monitoring Hardware

• Kill-A-Watt Meter: A device that measures power usage by connecting between the wall plug and the PSU's power cord.
• Current Clamp: A device used to measure the flow through the wires feeding each component.
• Passmark Inline PSU Tester: A device that enables diagnostics and troubleshooting for desktop PC power supplies. It can measure supply voltages, power consumption, ripple voltage, and timing for each voltage rail. It can be used in inline or standalone mode and can be connected to a PC via USB to monitor PSU statistics.

PSU power draw

To monitor PSU power draw, you can use a power supply calculator. This tool will help you determine the required watts and amps for your PC build by multiplying the total amperage (amps) drawn by all components by the total voltage (volts) they need.

There are various power supply calculators available online, such as Newegg's PSU calculator, which allows you to select the components you want, such as the CPU, GPU, and motherboard, and then estimates the power needs based on those components. It is highly accurate and can help you avoid issues like system instability.

Another option is to use a watt meter, which you can plug into the wall outlet before your PSU’s power cord to see exactly how much power is being drawn. You can then multiply that number by the efficiency of your PSU (usually indicated by a sticker on the PSU) and divide by 100 to get the actual power draw.

While there are software solutions that claim to monitor PSU power draw, these are generally inaccurate and not recommended.

PSU power consumption

There are several methods to monitor PSU power consumption, including software, hardware devices, and online tools.

Software

Measuring PSU power consumption through software is a convenient and often free method. However, it's important to note that software can only display power usage if the device contains appropriate sensors and associated 'flags'. CPUs and GPUs typically have these sensors, but most other devices do not. Examples of software that can be used to monitor PSU power consumption include HWMonitor, PC Wizard, Ryzen Master, and Power Gadget. While these programs can provide real-time power usage data, they may not always be accurate, especially for components without the necessary sensors.

Hardware Devices

For accurate readings of your PSU power consumption, dedicated hardware devices can be used. These devices are plugged into an outlet, and your PC is then plugged into the device, allowing it to measure the power drawn by your computer. Examples of such devices include the P4460 Kill A Watt EZ and the Belkin Conserve Insight F700-INSIGHT-PWR. The Belkin device also includes an easy-to-read LCD screen and two USB ports for device charging.

Online Tools

Online tools, such as the OuterVision Power Supply Calculator and the PSU Wattage Calculator from The Tech Buyer's Guru, can provide estimates of your PSU power consumption based on your PC's components. While these tools are convenient, they may not always give accurate readings.

Combination of Methods

For the most accurate assessment of your PSU power consumption, a combination of software and hardware methods is recommended. This can include using software to monitor individual component power usage, such as CPU and GPU power draw, while also utilising a dedicated power meter to measure the total power consumption of your PC.

By understanding and monitoring your PSU power consumption, you can make informed decisions to reduce your PC's power usage, optimise its performance, and prolong its lifespan.

PSU power meters

There are a few ways to monitor your PSU usage. One way is to use a power supply calculator, which will help you determine the required watts and amps for your PC build. You can find these calculators on websites like Newegg and OuterVision. These websites also offer tips on choosing the right PSU for your needs and offer product suggestions.

Another way to monitor your PSU usage is by using a watt meter. This device is plugged in between the wall plug and your PSU's power cord, and it will show exactly how much power is being drawn. You can then multiply this number by the efficiency of your PSU to get the total power consumption.

Additionally, some PSU units from manufacturers like Corsair have built-in features that allow you to monitor the voltages and other relevant data.

It is worth noting that there doesn't seem to be reliable software that can accurately monitor PSU usage. Any software that claims to do so is likely inadequate and unreliable.

PSU power-saving

If you're looking to save power and money on your electricity bill, investing in a high-efficiency power supply unit (PSU) could be a good idea. Here are some things to keep in mind:

80 Plus Certification

Look out for the 80 Plus certification when buying a new PSU. This means that the PSU is at least 80% efficient at 25%, 50%, 75%, and 100% of full load. The original concept has been revised, and now there are different levels of efficiency: Titanium, Platinum, Gold, Silver, and Bronze. These higher tiers have stricter efficiency requirements and generally come at a higher price.

Power Supply Efficiency

Power supply efficiency is the amount of power provided to your computer components divided by the amount of power drawn from the wall. So, for example, a 50% efficient PSU that needs to provide 50W of power will draw 100W from the electrical grid, losing the other 50W as heat. Most PSUs run at maximum efficiency at around 50% load.

Cost Savings

Whether you will save money by investing in a high-efficiency PSU depends on the average power draw of your PC and your local cost per kilowatt-hour. The higher the power draw, the more you will benefit from even small increases in efficiency. Similarly, the higher the cost per kilowatt-hour, the more you will save with a more efficient PSU.

Longevity and Reliability

More efficient PSUs tend to have better longevity and reliability. Less efficient PSUs generate more heat, which can cause more wear and tear and increase the failure rate. Extreme heat can also degrade other components in your PC, so a more efficient PSU can help extend the lifespan of your computer as a whole.

Standby Power Consumption

Even when your computer is shut down, the PSU continues to draw some power, known as standby or vampire power. Newer PSUs, especially those sold in Europe, draw less than 0.5W in this mode. If power conservation is important to you, look for a model with ErP Lot6 2013 support.
